Caution ndash Failure to identify the correct disk drive may result in replacing thewrong disk drive and could cause a loss of data Be sure that you have identified thecorrect disk drive
Caution ndash To prevent any possibility of data loss it is strongly recommended thatyou back up the data prior to removing disk drives
Caution ndash Do not remove a defective module unless you have a replacement FRUmodule to immediately replace the defective module If you remove a module anddo not replace it you alter the air flow inside the chassis and could overheat thechassis as a result
Note ndash A newly installed disk drive automatically rebuilds with the correct paritydata and association with logical drive if a functioning global or spare drive hasremained in the chassis Therefore do not remove and replace all drives at one timeIf more than one drive fails in a logical drive (except RAID 1+0) then the logicaldrive fails data is lost and the logical drive must be rebuilt
2-4 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Remove the defective disk drive with the following steps
1 Unlock the locks with the provided key and gently pull the plastic front bezelaway from the front of the unit so that it drops down and is supported by the twohinged brackets on the sides
2 Turn the thumbscrew counterclockwise several full turns until the thumbscrewand drive module are loosened
3 Gently pull the release handle upward
4 Pull the drive module out until the drive connector has fully disconnected fromthe midplane
5 Wait 20 seconds for the drive to stop spinning and then remove it from the chassis

Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-5
214 Scanning the New Drive and Related Procedures
2141 Scanning the New Drive
After you have replaced a disk drive perform the following steps
1 Check to see if drive was automatically scanned onto the bus
a From the Main Menu select ldquoview and edit scsi Drivesrdquo
b Check that the drive status of the disk drive
The status field will specify NEW_DRV or USED_DRV until it is assigned as aGLOBAL or LOCAL spare with STAND-BY status
2 If the disk drive was not automatically scanned scan the replaced disk drive intothe configuration with the following steps
a From the Main Menu select ldquoview and edit scsi Drivesrdquo Select any disk drivein the list press Return
b Select ldquoScan scsi driverdquo and press Return Select the Channel number then theID number of the replaced disk drive and confirm Yes when prompted
c Verify that the message ldquoScanned SCSI drive successfullyrdquo is displayed
3 From the Main Menu select ldquoview and edit Logical drivesrdquo and use the followingtable to continue
TABLE 2-1 Decision Table for Selecting Disk Drive Procedure
If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units

19 The new RAID array requires new cabling and first-time configuration
For cabling and configuration instructions refer to Chapters 4 and 5 in theinstallation manual
Note ndash Each operating system has additional procedures or requirements for seeinga new device For instructions related to each operating system refer to theappropriate appendix from the set of appendices E through J in the Sun StorEdgeInstallation Operation and Service Manual for your array
Note ndash In some operating systems you will also have obsolete files or pathsassociated with the removed JBOD unit for example in Solaris operating systemsses files are created for each JBOD drive under deves Consult your operatingsystem documentation for information on how to remove or modify appropriatefiles and paths
20 After you create RAID logical drives on the new RAID array restore the data ontothe drives
Note ndash You must use a tool within Solaris or an external software package toperform the data restore function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have restore functions for data

61 Replacing a SCSI Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
The controller modules are hot-swappable
611 Saving the Configuration Settings to NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set Before replacing a controller module save theconfiguration settings to NVRAM If power is removed before you replace a IOcontroller module the settings can be restored from NVRAM
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down select ldquocontroller maintenancerdquo and thenselect ldquosave NVRAM to disksrdquo and press Return
3 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
612 Removing a SCSI Controller Module1 Keep the array powered on
2 Turn the thumbscrews on the left and right sides of the controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the controller module
613 Installing a SCSI Controller Module1 Keep the array powered on Gently slide the controller module into the unit until
it clicks and is seated in the backplane
6-2 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
2 Turn the thumbscrews on the left and right sides of the controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster
Chapter 6 SCSI Module FRUs 6-3
3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)
6-4 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
3 Ensure that all SCSI cables attached to the IO module are labeled clearly Thenremove all SCSI cables attached to the IO module
Caution ndash The IO module offers resistance when you remove it from the chassisbackplane When unseating the module from the chassis check that you do not bendbackwards the ERROR LED mounted on the module
4 Turn the thumbscrews on the left and right sides of an IO modulecounterclockwise until the thumbscrews are disengaged from the chassis
5 Hold the thumbscrews and using a slight downward pressure pull evenly on thescrews to disengage the IO module
623 Installing a SCSI IO Module1 With the power still off slide the IO module into the chassis far enough to
engage the thumbscrews
Caution ndash Be sure that the IO module is properly inserted into the guide rails
2 Turn the thumbscrews on the left and right sides of the IO module clockwise astight as possible without using a screwdriver Then push firmly with a singlefirm two-handed push which should move the module about 1 cm
3 Tighten the thumbscrews again Then push firmly with a single firm two-handedpush Tighten the thumbscrews again until finger-tight
Note ndash An improperly seated IO module commonly causes SCSI channel errors
4 Reinstall all SCSI cables in their original positions
5 Power on both power supply modules
Chapter 6 SCSI Module FRUs 6-5
63 Replacing the SCSI Terminator ModuleBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
631 Removing the SCSI Terminator Module1 Power off both power supply modules on the array
Although the terminator module is technically hot-swappable most users power offthe array because the procedure requires that you will be removing and reinsertingthree modules during the procedure
Caution ndash Connected hosts must be inactive during this replacement procedure
2 Remove all serial and Ethernet cables connected to the controller modules
3 Remove both controller modules
a Turn the thumbscrews on the left and right sides of each controller modulecounterclockwise until the thumbscrews are disengaged from the chassis

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-5
214 Scanning the New Drive and Related Procedures
2141 Scanning the New Drive
After you have replaced a disk drive perform the following steps
1 Check to see if drive was automatically scanned onto the bus
a From the Main Menu select ldquoview and edit scsi Drivesrdquo
b Check that the drive status of the disk drive
The status field will specify NEW_DRV or USED_DRV until it is assigned as aGLOBAL or LOCAL spare with STAND-BY status

a From the Main Menu select ldquoview and edit scsi Drivesrdquo Select any disk drivein the list press Return
b Select ldquoScan scsi driverdquo and press Return Select the Channel number then theID number of the replaced disk drive and confirm Yes when prompted
c Verify that the message ldquoScanned SCSI drive successfullyrdquo is displayed
3 From the Main Menu select ldquoview and edit Logical drivesrdquo and use the followingtable to continue
TABLE 2-1 Decision Table for Selecting Disk Drive Procedure
If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)
6-4 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
3 Ensure that all SCSI cables attached to the IO module are labeled clearly Thenremove all SCSI cables attached to the IO module
Caution ndash The IO module offers resistance when you remove it from the chassisbackplane When unseating the module from the chassis check that you do not bendbackwards the ERROR LED mounted on the module
4 Turn the thumbscrews on the left and right sides of an IO modulecounterclockwise until the thumbscrews are disengaged from the chassis
5 Hold the thumbscrews and using a slight downward pressure pull evenly on thescrews to disengage the IO module
623 Installing a SCSI IO Module1 With the power still off slide the IO module into the chassis far enough to
engage the thumbscrews
Caution ndash Be sure that the IO module is properly inserted into the guide rails
2 Turn the thumbscrews on the left and right sides of the IO module clockwise astight as possible without using a screwdriver Then push firmly with a singlefirm two-handed push which should move the module about 1 cm
3 Tighten the thumbscrews again Then push firmly with a single firm two-handedpush Tighten the thumbscrews again until finger-tight
Note ndash An improperly seated IO module commonly causes SCSI channel errors
4 Reinstall all SCSI cables in their original positions
5 Power on both power supply modules

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo

18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

5-1
Caution ndash Connected hosts must be inactive during this replacement procedure
511 Saving the Configuration Settings to NVRAMBefore replacing a controller module save the configuration settings to NVRAM Ifpower is removed before you replace an IO controller module the settings can berestored from NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down and select ldquocontroller maintenancerdquo
3 Select ldquosave NVRAM to disksrdquo and press Return
4 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
512 Removing an IO Controller Module1 Keep the array powered on and make sure that the connected hosts are inactive
Note ndash Most users who have multiple host connections between the two controllersuse multi-pathing software to manage them If multi-pathing software andconnectivity is not possible one alternative is to power off the array and discontinueall host IO until the replacement is completed and the array is powered on
2 Write down the cabling configuration for the controller-to-host connection andexpansion unit connections so that you can reconnect the cables correctly with thenew IO controller module See FIGURE 5-1

Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade

16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

12 Static Electricity and Other PrecautionsFollow these steps to prevent damaging the FRUs
Remove plastic vinyl and foam from the work area
Before handling a FRU discharge any static electricity by touching a groundsurface
Wear an antistatic wrist strip
Do not remove a FRU from its antistatic protective bag until you are ready toinstall it
When removing a FRU from the array immediately place it in an antistatic bagand in antistatic packaging
Handle a FRU only by its edges and avoid touching the circuitry
Do not slide a FRU over any surface
Limit body movement (which builds up static electricity) during FRU installation
Caution ndash To prevent any possibility of data loss it is strongly recommended thatyou back up the data prior to removing disk drives
Caution ndash Do not remove a defective module unless you have a replacement FRUmodule to immediately replace the defective module If you remove a module anddo not replace it you alter the air flow inside the chassis and could overheat thechassis as a result

Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-5
214 Scanning the New Drive and Related Procedures
2141 Scanning the New Drive
After you have replaced a disk drive perform the following steps
1 Check to see if drive was automatically scanned onto the bus
a From the Main Menu select ldquoview and edit scsi Drivesrdquo
b Check that the drive status of the disk drive
The status field will specify NEW_DRV or USED_DRV until it is assigned as aGLOBAL or LOCAL spare with STAND-BY status

a From the Main Menu select ldquoview and edit scsi Drivesrdquo Select any disk drivein the list press Return
b Select ldquoScan scsi driverdquo and press Return Select the Channel number then theID number of the replaced disk drive and confirm Yes when prompted
c Verify that the message ldquoScanned SCSI drive successfullyrdquo is displayed
3 From the Main Menu select ldquoview and edit Logical drivesrdquo and use the followingtable to continue
TABLE 2-1 Decision Table for Selecting Disk Drive Procedure
If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units

61 Replacing a SCSI Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
The controller modules are hot-swappable
611 Saving the Configuration Settings to NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set Before replacing a controller module save theconfiguration settings to NVRAM If power is removed before you replace a IOcontroller module the settings can be restored from NVRAM
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down select ldquocontroller maintenancerdquo and thenselect ldquosave NVRAM to disksrdquo and press Return
3 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
612 Removing a SCSI Controller Module1 Keep the array powered on
2 Turn the thumbscrews on the left and right sides of the controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the controller module
613 Installing a SCSI Controller Module1 Keep the array powered on Gently slide the controller module into the unit until
it clicks and is seated in the backplane
6-2 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
2 Turn the thumbscrews on the left and right sides of the controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster
Chapter 6 SCSI Module FRUs 6-3
3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)
6-4 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
3 Ensure that all SCSI cables attached to the IO module are labeled clearly Thenremove all SCSI cables attached to the IO module
Caution ndash The IO module offers resistance when you remove it from the chassisbackplane When unseating the module from the chassis check that you do not bendbackwards the ERROR LED mounted on the module
4 Turn the thumbscrews on the left and right sides of an IO modulecounterclockwise until the thumbscrews are disengaged from the chassis
5 Hold the thumbscrews and using a slight downward pressure pull evenly on thescrews to disengage the IO module
623 Installing a SCSI IO Module1 With the power still off slide the IO module into the chassis far enough to
engage the thumbscrews
Caution ndash Be sure that the IO module is properly inserted into the guide rails
2 Turn the thumbscrews on the left and right sides of the IO module clockwise astight as possible without using a screwdriver Then push firmly with a singlefirm two-handed push which should move the module about 1 cm
3 Tighten the thumbscrews again Then push firmly with a single firm two-handedpush Tighten the thumbscrews again until finger-tight
Note ndash An improperly seated IO module commonly causes SCSI channel errors
4 Reinstall all SCSI cables in their original positions
5 Power on both power supply modules
Chapter 6 SCSI Module FRUs 6-5
63 Replacing the SCSI Terminator ModuleBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
631 Removing the SCSI Terminator Module1 Power off both power supply modules on the array
Although the terminator module is technically hot-swappable most users power offthe array because the procedure requires that you will be removing and reinsertingthree modules during the procedure
Caution ndash Connected hosts must be inactive during this replacement procedure
2 Remove all serial and Ethernet cables connected to the controller modules
3 Remove both controller modules
a Turn the thumbscrews on the left and right sides of each controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the controller module
4 Hold the terminator module by the front edges and pull it out of the chassis

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

5-1
Caution ndash Connected hosts must be inactive during this replacement procedure
511 Saving the Configuration Settings to NVRAMBefore replacing a controller module save the configuration settings to NVRAM Ifpower is removed before you replace an IO controller module the settings can berestored from NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down and select ldquocontroller maintenancerdquo
3 Select ldquosave NVRAM to disksrdquo and press Return
4 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
512 Removing an IO Controller Module1 Keep the array powered on and make sure that the connected hosts are inactive
Note ndash Most users who have multiple host connections between the two controllersuse multi-pathing software to manage them If multi-pathing software andconnectivity is not possible one alternative is to power off the array and discontinueall host IO until the replacement is completed and the array is powered on
2 Write down the cabling configuration for the controller-to-host connection andexpansion unit connections so that you can reconnect the cables correctly with thenew IO controller module See FIGURE 5-1
3 Remove all cables from the IO controller module

513 Installing an IO Controller Module1 Keep the array powered on Gently slide the IO controller module into the unit
until it clicks and is seated in the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray and that you keep the power on If you power off and then replace themodule you will have to continue with additional steps Refer to ldquoIO ControllerReplacement for a Single-Controller or Powered-Off Arrayrdquo on page 5-5
2 Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade

6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

12 Static Electricity and Other PrecautionsFollow these steps to prevent damaging the FRUs
Remove plastic vinyl and foam from the work area
Before handling a FRU discharge any static electricity by touching a groundsurface
Wear an antistatic wrist strip
Do not remove a FRU from its antistatic protective bag until you are ready toinstall it
When removing a FRU from the array immediately place it in an antistatic bagand in antistatic packaging
Handle a FRU only by its edges and avoid touching the circuitry
Do not slide a FRU over any surface
Limit body movement (which builds up static electricity) during FRU installation
Caution ndash To prevent any possibility of data loss it is strongly recommended thatyou back up the data prior to removing disk drives
Caution ndash Do not remove a defective module unless you have a replacement FRUmodule to immediately replace the defective module If you remove a module anddo not replace it you alter the air flow inside the chassis and could overheat thechassis as a result

212 Removing a Defective Disk Drive
Caution ndash Failure to identify the correct disk drive may result in replacing thewrong disk drive and could cause a loss of data Be sure that you have identified thecorrect disk drive
Caution ndash To prevent any possibility of data loss it is strongly recommended thatyou back up the data prior to removing disk drives
Caution ndash Do not remove a defective module unless you have a replacement FRUmodule to immediately replace the defective module If you remove a module anddo not replace it you alter the air flow inside the chassis and could overheat thechassis as a result
Note ndash A newly installed disk drive automatically rebuilds with the correct paritydata and association with logical drive if a functioning global or spare drive hasremained in the chassis Therefore do not remove and replace all drives at one timeIf more than one drive fails in a logical drive (except RAID 1+0) then the logicaldrive fails data is lost and the logical drive must be rebuilt

c Verify that the message ldquoScanned SCSI drive successfullyrdquo is displayed
3 From the Main Menu select ldquoview and edit Logical drivesrdquo and use the followingtable to continue
TABLE 2-1 Decision Table for Selecting Disk Drive Procedure
If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module

6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly

10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo

a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

2141 Scanning the New Drive
After you have replaced a disk drive perform the following steps
1 Check to see if drive was automatically scanned onto the bus
a From the Main Menu select ldquoview and edit scsi Drivesrdquo
b Check that the drive status of the disk drive
The status field will specify NEW_DRV or USED_DRV until it is assigned as aGLOBAL or LOCAL spare with STAND-BY status

If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps

d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

12 Static Electricity and Other PrecautionsFollow these steps to prevent damaging the FRUs
Remove plastic vinyl and foam from the work area
Before handling a FRU discharge any static electricity by touching a groundsurface
Wear an antistatic wrist strip
Do not remove a FRU from its antistatic protective bag until you are ready toinstall it
When removing a FRU from the array immediately place it in an antistatic bagand in antistatic packaging
Handle a FRU only by its edges and avoid touching the circuitry
Do not slide a FRU over any surface
Limit body movement (which builds up static electricity) during FRU installation
Caution ndash To prevent any possibility of data loss it is strongly recommended thatyou back up the data prior to removing disk drives
Caution ndash Do not remove a defective module unless you have a replacement FRUmodule to immediately replace the defective module If you remove a module anddo not replace it you alter the air flow inside the chassis and could overheat thechassis as a result

If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

212 Removing a Defective Disk Drive
Caution ndash Failure to identify the correct disk drive may result in replacing thewrong disk drive and could cause a loss of data Be sure that you have identified thecorrect disk drive
Caution ndash To prevent any possibility of data loss it is strongly recommended thatyou back up the data prior to removing disk drives
Caution ndash Do not remove a defective module unless you have a replacement FRUmodule to immediately replace the defective module If you remove a module anddo not replace it you alter the air flow inside the chassis and could overheat thechassis as a result
Note ndash A newly installed disk drive automatically rebuilds with the correct paritydata and association with logical drive if a functioning global or spare drive hasremained in the chassis Therefore do not remove and replace all drives at one timeIf more than one drive fails in a logical drive (except RAID 1+0) then the logicaldrive fails data is lost and the logical drive must be rebuilt

Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-5
214 Scanning the New Drive and Related Procedures
2141 Scanning the New Drive
After you have replaced a disk drive perform the following steps
1 Check to see if drive was automatically scanned onto the bus
a From the Main Menu select ldquoview and edit scsi Drivesrdquo
b Check that the drive status of the disk drive
The status field will specify NEW_DRV or USED_DRV until it is assigned as aGLOBAL or LOCAL spare with STAND-BY status

a From the Main Menu select ldquoview and edit scsi Drivesrdquo Select any disk drivein the list press Return
b Select ldquoScan scsi driverdquo and press Return Select the Channel number then theID number of the replaced disk drive and confirm Yes when prompted
c Verify that the message ldquoScanned SCSI drive successfullyrdquo is displayed
3 From the Main Menu select ldquoview and edit Logical drivesrdquo and use the followingtable to continue
TABLE 2-1 Decision Table for Selecting Disk Drive Procedure
If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

51 Replacing an IO Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4 The IOcontroller modules are hot-serviceable Hot-serviceable means that the module canbe replaced while the array and hosts are powered on but the connected hosts mustbe inactive
5-1
Caution ndash Connected hosts must be inactive during this replacement procedure
511 Saving the Configuration Settings to NVRAMBefore replacing a controller module save the configuration settings to NVRAM Ifpower is removed before you replace an IO controller module the settings can berestored from NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down and select ldquocontroller maintenancerdquo
3 Select ldquosave NVRAM to disksrdquo and press Return
4 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
512 Removing an IO Controller Module1 Keep the array powered on and make sure that the connected hosts are inactive
Note ndash Most users who have multiple host connections between the two controllersuse multi-pathing software to manage them If multi-pathing software andconnectivity is not possible one alternative is to power off the array and discontinueall host IO until the replacement is completed and the array is powered on
2 Write down the cabling configuration for the controller-to-host connection andexpansion unit connections so that you can reconnect the cables correctly with thenew IO controller module See FIGURE 5-1
3 Remove all cables from the IO controller module
4 Turn the thumbscrews on the left and right sides of the IO controller modulecounterclockwise until the thumbscrews are disengaged from the chassis

513 Installing an IO Controller Module1 Keep the array powered on Gently slide the IO controller module into the unit
until it clicks and is seated in the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray and that you keep the power on If you power off and then replace themodule you will have to continue with additional steps Refer to ldquoIO ControllerReplacement for a Single-Controller or Powered-Off Arrayrdquo on page 5-5
2 Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

515 IO Controller Replacement for a Single-Controller or Powered-Off ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo then select ldquoController Parametersrdquo and press Return

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

212 Removing a Defective Disk Drive
Caution ndash Failure to identify the correct disk drive may result in replacing thewrong disk drive and could cause a loss of data Be sure that you have identified thecorrect disk drive
Caution ndash To prevent any possibility of data loss it is strongly recommended thatyou back up the data prior to removing disk drives
Caution ndash Do not remove a defective module unless you have a replacement FRUmodule to immediately replace the defective module If you remove a module anddo not replace it you alter the air flow inside the chassis and could overheat thechassis as a result
Note ndash A newly installed disk drive automatically rebuilds with the correct paritydata and association with logical drive if a functioning global or spare drive hasremained in the chassis Therefore do not remove and replace all drives at one timeIf more than one drive fails in a logical drive (except RAID 1+0) then the logicaldrive fails data is lost and the logical drive must be rebuilt

a From the Main Menu select ldquoview and edit scsi Drivesrdquo Select any disk drivein the list press Return
b Select ldquoScan scsi driverdquo and press Return Select the Channel number then theID number of the replaced disk drive and confirm Yes when prompted
c Verify that the message ldquoScanned SCSI drive successfullyrdquo is displayed
3 From the Main Menu select ldquoview and edit Logical drivesrdquo and use the followingtable to continue
TABLE 2-1 Decision Table for Selecting Disk Drive Procedure
If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units

Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
2 Turn the thumbscrews on the left and right sides of the controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo

a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

212 Removing a Defective Disk Drive
Caution ndash Failure to identify the correct disk drive may result in replacing thewrong disk drive and could cause a loss of data Be sure that you have identified thecorrect disk drive
Caution ndash To prevent any possibility of data loss it is strongly recommended thatyou back up the data prior to removing disk drives
Caution ndash Do not remove a defective module unless you have a replacement FRUmodule to immediately replace the defective module If you remove a module anddo not replace it you alter the air flow inside the chassis and could overheat thechassis as a result
Note ndash A newly installed disk drive automatically rebuilds with the correct paritydata and association with logical drive if a functioning global or spare drive hasremained in the chassis Therefore do not remove and replace all drives at one timeIf more than one drive fails in a logical drive (except RAID 1+0) then the logicaldrive fails data is lost and the logical drive must be rebuilt

3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo

b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-5
214 Scanning the New Drive and Related Procedures
2141 Scanning the New Drive
After you have replaced a disk drive perform the following steps
1 Check to see if drive was automatically scanned onto the bus
a From the Main Menu select ldquoview and edit scsi Drivesrdquo
b Check that the drive status of the disk drive
The status field will specify NEW_DRV or USED_DRV until it is assigned as aGLOBAL or LOCAL spare with STAND-BY status
2 If the disk drive was not automatically scanned scan the replaced disk drive intothe configuration with the following steps
a From the Main Menu select ldquoview and edit scsi Drivesrdquo Select any disk drivein the list press Return
b Select ldquoScan scsi driverdquo and press Return Select the Channel number then theID number of the replaced disk drive and confirm Yes when prompted
c Verify that the message ldquoScanned SCSI drive successfullyrdquo is displayed
3 From the Main Menu select ldquoview and edit Logical drivesrdquo and use the followingtable to continue
TABLE 2-1 Decision Table for Selecting Disk Drive Procedure
If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

5-1
Caution ndash Connected hosts must be inactive during this replacement procedure
511 Saving the Configuration Settings to NVRAMBefore replacing a controller module save the configuration settings to NVRAM Ifpower is removed before you replace an IO controller module the settings can berestored from NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down and select ldquocontroller maintenancerdquo
3 Select ldquosave NVRAM to disksrdquo and press Return
4 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
512 Removing an IO Controller Module1 Keep the array powered on and make sure that the connected hosts are inactive
Note ndash Most users who have multiple host connections between the two controllersuse multi-pathing software to manage them If multi-pathing software andconnectivity is not possible one alternative is to power off the array and discontinueall host IO until the replacement is completed and the array is powered on
2 Write down the cabling configuration for the controller-to-host connection andexpansion unit connections so that you can reconnect the cables correctly with thenew IO controller module See FIGURE 5-1
3 Remove all cables from the IO controller module
4 Turn the thumbscrews on the left and right sides of the IO controller modulecounterclockwise until the thumbscrews are disengaged from the chassis

513 Installing an IO Controller Module1 Keep the array powered on Gently slide the IO controller module into the unit
until it clicks and is seated in the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray and that you keep the power on If you power off and then replace themodule you will have to continue with additional steps Refer to ldquoIO ControllerReplacement for a Single-Controller or Powered-Off Arrayrdquo on page 5-5
2 Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

515 IO Controller Replacement for a Single-Controller or Powered-Off ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo then select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained thisfeature is especially important in a Sun Cluster environment to maintain thesame disk device names in a cluster
3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
52 Replacing IO Expansion ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
All IO expansion modules are hot-serviceable Hot-serviceable means that themodule can be replaced while the array and hosts are powered on but the connectedhosts must be inactive
Chapter 5 FC Module FRUs 5-5
Caution ndash When you replace an IO expansion module the connected hosts mustbe inactive during the replacement procedure

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

214 Scanning the New Drive and Related Procedures
2141 Scanning the New Drive
After you have replaced a disk drive perform the following steps
1 Check to see if drive was automatically scanned onto the bus
a From the Main Menu select ldquoview and edit scsi Drivesrdquo
b Check that the drive status of the disk drive
The status field will specify NEW_DRV or USED_DRV until it is assigned as aGLOBAL or LOCAL spare with STAND-BY status
2 If the disk drive was not automatically scanned scan the replaced disk drive intothe configuration with the following steps
a From the Main Menu select ldquoview and edit scsi Drivesrdquo Select any disk drivein the list press Return
b Select ldquoScan scsi driverdquo and press Return Select the Channel number then theID number of the replaced disk drive and confirm Yes when prompted
c Verify that the message ldquoScanned SCSI drive successfullyrdquo is displayed
3 From the Main Menu select ldquoview and edit Logical drivesrdquo and use the followingtable to continue
TABLE 2-1 Decision Table for Selecting Disk Drive Procedure
If this drive status occurs Perform this task
If the target logical drive status is GOOD the sparedisk has successfully protected it and is nowintegrated into the logical drive and thereplacement disk drive is available to be assigned
Go to ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
If the target logical drive status is FATAL FAIL andtwo or more disk drives have failed
All data in the logical drive is lost Rebuild the logicaldrive and restore backup data
The logical drive status of DRV ABSENT orINCOMPLETE only occur at chassis powerupDRV ABSENT indicates that one drive is badINCOMPLETE indicates that two or more drivesare bad
Go to ldquoChecking and Performing the Correct PowerupSequencerdquo on page 2-7
If the target logical drive status is DRV FAILED If this occurs after a new drive has replaced the defectivedrive indicates a bad midplane Replace the chassis
If the target logical drive status is REBUILDING Go to ldquoIf the Logical Drive Status is REBUILDINGrdquo onpage 2-8
2-6 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

2142 Checking and Performing the Correct Powerup Sequence
Review the power-up sequence which you most recently used with the array If youare uncertain about the powerup sequence used repeat the power-up sequence inthe following order and see if it changes the logical drive status to GOOD
1 Power up the arrays and associated server as follows
Expansion unit(s) first RAID array next Host server(s) last (if they had been powered down for maintenance purposes)
2 Check the logical drive status in the ldquoview and edit Logical driverdquo window If thestatus is GOOD no further steps are needed
3 If the logical drive status is INCOMPLETE two or more disk drives have faileddata is lost and you have to rebuild a new logical drive
4 If the logical drive status is DRV ABSENT replace the defective disk drive andassign it as a global spare See ldquoAssigning a Disk Drive as a Sparerdquo on page 2-8
5 If the logical drive status is DRV ABSENT and the drive replacement is delayedtry to recover the defective drive so that it is operational during the wait periodand you can make a full backup of the data
a On the firmware main menu select ldquoview and edit Configuration parametersrdquoand press Return
b Select ldquoDrive-side SCSI Parametersrdquo and press Return
c Select ldquoDisk Access Delay Timerdquo and press Return
d Change the value to 60 seconds and press Return
e Select Yes to confirm the setting
f Reboot the array
g Check the logical drive status in the ldquoview and edit Logical driverdquo window
If the status is GOOD the drive has recovered and the logical drive is no longer ina critical state The original defective disk drive should work correctly for a timebut should still be replaced
If the status is DRV ABSENT or DRV FAILED replace the drive as quickly aspossible
h Back up the logical drive data onto another storage medium
Chapter 2 Disk Drive Air Management Sled and Tabletop Cover FRUs 2-7
2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units

61 Replacing a SCSI Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
The controller modules are hot-swappable
611 Saving the Configuration Settings to NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set Before replacing a controller module save theconfiguration settings to NVRAM If power is removed before you replace a IOcontroller module the settings can be restored from NVRAM
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down select ldquocontroller maintenancerdquo and thenselect ldquosave NVRAM to disksrdquo and press Return
3 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
612 Removing a SCSI Controller Module1 Keep the array powered on
2 Turn the thumbscrews on the left and right sides of the controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the controller module
613 Installing a SCSI Controller Module1 Keep the array powered on Gently slide the controller module into the unit until
it clicks and is seated in the backplane
6-2 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
2 Turn the thumbscrews on the left and right sides of the controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster

3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)
6-4 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
3 Ensure that all SCSI cables attached to the IO module are labeled clearly Thenremove all SCSI cables attached to the IO module
Caution ndash The IO module offers resistance when you remove it from the chassisbackplane When unseating the module from the chassis check that you do not bendbackwards the ERROR LED mounted on the module
4 Turn the thumbscrews on the left and right sides of an IO modulecounterclockwise until the thumbscrews are disengaged from the chassis
5 Hold the thumbscrews and using a slight downward pressure pull evenly on thescrews to disengage the IO module
623 Installing a SCSI IO Module1 With the power still off slide the IO module into the chassis far enough to
engage the thumbscrews
Caution ndash Be sure that the IO module is properly inserted into the guide rails
2 Turn the thumbscrews on the left and right sides of the IO module clockwise astight as possible without using a screwdriver Then push firmly with a singlefirm two-handed push which should move the module about 1 cm
3 Tighten the thumbscrews again Then push firmly with a single firm two-handedpush Tighten the thumbscrews again until finger-tight
Note ndash An improperly seated IO module commonly causes SCSI channel errors
4 Reinstall all SCSI cables in their original positions
5 Power on both power supply modules
Chapter 6 SCSI Module FRUs 6-5
63 Replacing the SCSI Terminator ModuleBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
631 Removing the SCSI Terminator Module1 Power off both power supply modules on the array
Although the terminator module is technically hot-swappable most users power offthe array because the procedure requires that you will be removing and reinsertingthree modules during the procedure
Caution ndash Connected hosts must be inactive during this replacement procedure
2 Remove all serial and Ethernet cables connected to the controller modules
3 Remove both controller modules
a Turn the thumbscrews on the left and right sides of each controller modulecounterclockwise until the thumbscrews are disengaged from the chassis

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

2143 Assigning a Disk Drive as a Spare
1 From the Main Menu select ldquoview and edit scsi Drivesrdquo
2 Select the replaced disk drive and press Return (its LG_DRV membership shouldbe NONE or an empty field)
3 Select ldquoAdd global spare driverdquo Select the target logical drive then confirm Yeswhen prompted
4 Disable Periodic Drive Check Time
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoDrive-side SCSI Parametersrdquo
Set the option Periodic Drive Check Time to Disabled then confirm Yes Thisprocedure is now complete
2144 If the Logical Drive Status is REBUILDING
The rebuilding process refers to the rebuilding of the logical drive in which the datafrom the defective disk drive is moved onto the global spare
When you see the REBUILDING status perform one of the two followingprocedures
Wait until the rebuild process is completed then replace the defective disk driveThe benefit is that the logical drive is fully restored before you replace thedefective drive This eliminates the possibility of lost data if the wrong drive isremoved
or
Replace the defective drive and make it a global spare while the rebuildingprocess continues
This procedure installs the new drive and assigns it as a global spare so thatautomatic rebuild of a logical drive will occur if a drive fails on any other logicaldrive on the array
Note ndash If a disk drive fails on another logical drive prior to the assignment of a newglobal spare you will have to manually rebuild the logical drive

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units

6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits

18 If you are creating a dual-controller RAID array perform the following steps withthe firmware application to ensure compatibility
5-18 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a To check the controller firmware version of each module perform these steps
Remove one IO controller module so that only one IO controller moduleremains in the array
Maintain a serial port connection to a terminal or workstation as described in step10
In the firmware application select ldquoview system Informationrdquo and record theFirmware Version
Insert the second IO controller module remove the first module and selectldquoview system Informationrdquo to record the Firmware Version of the second module
To check that you have the latest firmware go to
httpsunsolvesuncom
and select Patch Portal and then browse in the Sun Alert Patch Report or checkthe Sun StorEdge 3510 FC Release Notes for firmware patch information
b Check the number on each IO controller module faceplate where there is afour-digit number such as 0350 or 0450
Both IO controller modules must have the same first two digits which representa SESPLD firmware level in the module If the two modules have two differentnumbers for example 03 and 04 you must upgrade one IO controller module tothe higher level or both modules to the latest SESPLD level For moreinformation refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
c If the firmware versions of the two IO controller modules do not matchdownload the latest firmware to each IO controller module to ensure that theyhave the latest firmware and the same firmware
To download new versions of controller firmware disk drive firmware orSESPLD firmware use one of the following tools and check the Sun StorEdge3510 Release Notes or Sun Solve for the latest firmware patch

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly

10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo

a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array

11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo

a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly

10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo

a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD

5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly

6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo

17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade

61 Replacing a SCSI Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
The controller modules are hot-swappable
611 Saving the Configuration Settings to NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set Before replacing a controller module save theconfiguration settings to NVRAM If power is removed before you replace a IOcontroller module the settings can be restored from NVRAM
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down select ldquocontroller maintenancerdquo and thenselect ldquosave NVRAM to disksrdquo and press Return
3 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
612 Removing a SCSI Controller Module1 Keep the array powered on
2 Turn the thumbscrews on the left and right sides of the controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the controller module
613 Installing a SCSI Controller Module1 Keep the array powered on Gently slide the controller module into the unit until
it clicks and is seated in the backplane
6-2 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
2 Turn the thumbscrews on the left and right sides of the controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)

3 Ensure that all SCSI cables attached to the IO module are labeled clearly Thenremove all SCSI cables attached to the IO module
Caution ndash The IO module offers resistance when you remove it from the chassisbackplane When unseating the module from the chassis check that you do not bendbackwards the ERROR LED mounted on the module
4 Turn the thumbscrews on the left and right sides of an IO modulecounterclockwise until the thumbscrews are disengaged from the chassis
5 Hold the thumbscrews and using a slight downward pressure pull evenly on thescrews to disengage the IO module
623 Installing a SCSI IO Module1 With the power still off slide the IO module into the chassis far enough to
engage the thumbscrews
Caution ndash Be sure that the IO module is properly inserted into the guide rails
2 Turn the thumbscrews on the left and right sides of the IO module clockwise astight as possible without using a screwdriver Then push firmly with a singlefirm two-handed push which should move the module about 1 cm
3 Tighten the thumbscrews again Then push firmly with a single firm two-handedpush Tighten the thumbscrews again until finger-tight
Note ndash An improperly seated IO module commonly causes SCSI channel errors
4 Reinstall all SCSI cables in their original positions
5 Power on both power supply modules

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo

a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits

614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)

d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI

19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

51 Replacing an IO Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4 The IOcontroller modules are hot-serviceable Hot-serviceable means that the module canbe replaced while the array and hosts are powered on but the connected hosts mustbe inactive
5-1
Caution ndash Connected hosts must be inactive during this replacement procedure
511 Saving the Configuration Settings to NVRAMBefore replacing a controller module save the configuration settings to NVRAM Ifpower is removed before you replace an IO controller module the settings can berestored from NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down and select ldquocontroller maintenancerdquo
3 Select ldquosave NVRAM to disksrdquo and press Return
4 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
512 Removing an IO Controller Module1 Keep the array powered on and make sure that the connected hosts are inactive
Note ndash Most users who have multiple host connections between the two controllersuse multi-pathing software to manage them If multi-pathing software andconnectivity is not possible one alternative is to power off the array and discontinueall host IO until the replacement is completed and the array is powered on
2 Write down the cabling configuration for the controller-to-host connection andexpansion unit connections so that you can reconnect the cables correctly with thenew IO controller module See FIGURE 5-1
3 Remove all cables from the IO controller module
4 Turn the thumbscrews on the left and right sides of the IO controller modulecounterclockwise until the thumbscrews are disengaged from the chassis

Chapter 5 FC Module FRUs 5-3
513 Installing an IO Controller Module1 Keep the array powered on Gently slide the IO controller module into the unit
until it clicks and is seated in the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray and that you keep the power on If you power off and then replace themodule you will have to continue with additional steps Refer to ldquoIO ControllerReplacement for a Single-Controller or Powered-Off Arrayrdquo on page 5-5
2 Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

515 IO Controller Replacement for a Single-Controller or Powered-Off ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo then select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained thisfeature is especially important in a Sun Cluster environment to maintain thesame disk device names in a cluster
3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
52 Replacing IO Expansion ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
All IO expansion modules are hot-serviceable Hot-serviceable means that themodule can be replaced while the array and hosts are powered on but the connectedhosts must be inactive
Chapter 5 FC Module FRUs 5-5

Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

51 Replacing an IO Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4 The IOcontroller modules are hot-serviceable Hot-serviceable means that the module canbe replaced while the array and hosts are powered on but the connected hosts mustbe inactive
5-1
Caution ndash Connected hosts must be inactive during this replacement procedure
511 Saving the Configuration Settings to NVRAMBefore replacing a controller module save the configuration settings to NVRAM Ifpower is removed before you replace an IO controller module the settings can berestored from NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down and select ldquocontroller maintenancerdquo
3 Select ldquosave NVRAM to disksrdquo and press Return
4 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
512 Removing an IO Controller Module1 Keep the array powered on and make sure that the connected hosts are inactive
Note ndash Most users who have multiple host connections between the two controllersuse multi-pathing software to manage them If multi-pathing software andconnectivity is not possible one alternative is to power off the array and discontinueall host IO until the replacement is completed and the array is powered on
2 Write down the cabling configuration for the controller-to-host connection andexpansion unit connections so that you can reconnect the cables correctly with thenew IO controller module See FIGURE 5-1
3 Remove all cables from the IO controller module
4 Turn the thumbscrews on the left and right sides of the IO controller modulecounterclockwise until the thumbscrews are disengaged from the chassis

513 Installing an IO Controller Module1 Keep the array powered on Gently slide the IO controller module into the unit
until it clicks and is seated in the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray and that you keep the power on If you power off and then replace themodule you will have to continue with additional steps Refer to ldquoIO ControllerReplacement for a Single-Controller or Powered-Off Arrayrdquo on page 5-5
2 Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

515 IO Controller Replacement for a Single-Controller or Powered-Off ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo then select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained thisfeature is especially important in a Sun Cluster environment to maintain thesame disk device names in a cluster
3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
52 Replacing IO Expansion ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
All IO expansion modules are hot-serviceable Hot-serviceable means that themodule can be replaced while the array and hosts are powered on but the connectedhosts must be inactive
Chapter 5 FC Module FRUs 5-5
Caution ndash When you replace an IO expansion module the connected hosts mustbe inactive during the replacement procedure
521 Removing the IO Expansion Module1 Keep the array powered on and be sure that the connected hosts are inactive
during this procedure
2 Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the IO expansion module
522 Installing the IO Expansion Module1 Keep the array powered on and be sure that the connected hosts are inactive
during this procedure
2 Slide the IO expansion module into the chassis until the module is firmly seatedin the backplane and the modulersquos front panel is flush with the chassis
Caution ndash Be sure that the IO expansion module is properly inserted into theguide rails of the array
3 Turn the thumbscrews on the left and right sides of the IO expansion moduleclockwise until the thumbscrews are finger-tight to secure the module
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
If you power on the expansion unit hear an audible alarm and see a blinking amberEvent light on the front of your array the new controller has a different version ofSES or PLD firmware than the other IO controller in your array To solve thismismatch refer to ldquoSES Firmware Update Sometimes Required with IO ControllerModule Replacementsrdquo on page 5-7

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo

b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

51 Replacing an IO Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4 The IOcontroller modules are hot-serviceable Hot-serviceable means that the module canbe replaced while the array and hosts are powered on but the connected hosts mustbe inactive
5-1
Caution ndash Connected hosts must be inactive during this replacement procedure
511 Saving the Configuration Settings to NVRAMBefore replacing a controller module save the configuration settings to NVRAM Ifpower is removed before you replace an IO controller module the settings can berestored from NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down and select ldquocontroller maintenancerdquo
3 Select ldquosave NVRAM to disksrdquo and press Return
4 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
512 Removing an IO Controller Module1 Keep the array powered on and make sure that the connected hosts are inactive
Note ndash Most users who have multiple host connections between the two controllersuse multi-pathing software to manage them If multi-pathing software andconnectivity is not possible one alternative is to power off the array and discontinueall host IO until the replacement is completed and the array is powered on
2 Write down the cabling configuration for the controller-to-host connection andexpansion unit connections so that you can reconnect the cables correctly with thenew IO controller module See FIGURE 5-1
3 Remove all cables from the IO controller module

513 Installing an IO Controller Module1 Keep the array powered on Gently slide the IO controller module into the unit
until it clicks and is seated in the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray and that you keep the power on If you power off and then replace themodule you will have to continue with additional steps Refer to ldquoIO ControllerReplacement for a Single-Controller or Powered-Off Arrayrdquo on page 5-5
2 Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

For cabling and configuration instructions refer to Chapters 4 and 5 in theinstallation manual
Note ndash Each operating system has additional procedures or requirements for seeinga new device For instructions related to each operating system refer to theappropriate appendix from the set of appendices E through J in the Sun StorEdgeInstallation Operation and Service Manual for your array
Note ndash In some operating systems you will also have obsolete files or pathsassociated with the removed JBOD unit for example in Solaris operating systemsses files are created for each JBOD drive under deves Consult your operatingsystem documentation for information on how to remove or modify appropriatefiles and paths
20 After you create RAID logical drives on the new RAID array restore the data ontothe drives
Note ndash You must use a tool within Solaris or an external software package toperform the data restore function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have restore functions for data

61 Replacing a SCSI Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
The controller modules are hot-swappable
611 Saving the Configuration Settings to NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set Before replacing a controller module save theconfiguration settings to NVRAM If power is removed before you replace a IOcontroller module the settings can be restored from NVRAM
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down select ldquocontroller maintenancerdquo and thenselect ldquosave NVRAM to disksrdquo and press Return
3 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
612 Removing a SCSI Controller Module1 Keep the array powered on
2 Turn the thumbscrews on the left and right sides of the controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the controller module
613 Installing a SCSI Controller Module1 Keep the array powered on Gently slide the controller module into the unit until
it clicks and is seated in the backplane
6-2 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
2 Turn the thumbscrews on the left and right sides of the controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster

3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)
6-4 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
3 Ensure that all SCSI cables attached to the IO module are labeled clearly Thenremove all SCSI cables attached to the IO module
Caution ndash The IO module offers resistance when you remove it from the chassisbackplane When unseating the module from the chassis check that you do not bendbackwards the ERROR LED mounted on the module
4 Turn the thumbscrews on the left and right sides of an IO modulecounterclockwise until the thumbscrews are disengaged from the chassis
5 Hold the thumbscrews and using a slight downward pressure pull evenly on thescrews to disengage the IO module
623 Installing a SCSI IO Module1 With the power still off slide the IO module into the chassis far enough to
engage the thumbscrews
Caution ndash Be sure that the IO module is properly inserted into the guide rails
2 Turn the thumbscrews on the left and right sides of the IO module clockwise astight as possible without using a screwdriver Then push firmly with a singlefirm two-handed push which should move the module about 1 cm
3 Tighten the thumbscrews again Then push firmly with a single firm two-handedpush Tighten the thumbscrews again until finger-tight
Note ndash An improperly seated IO module commonly causes SCSI channel errors
4 Reinstall all SCSI cables in their original positions
5 Power on both power supply modules
Chapter 6 SCSI Module FRUs 6-5
63 Replacing the SCSI Terminator ModuleBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
631 Removing the SCSI Terminator Module1 Power off both power supply modules on the array
Although the terminator module is technically hot-swappable most users power offthe array because the procedure requires that you will be removing and reinsertingthree modules during the procedure
Caution ndash Connected hosts must be inactive during this replacement procedure

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI

d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

5-1
Caution ndash Connected hosts must be inactive during this replacement procedure
511 Saving the Configuration Settings to NVRAMBefore replacing a controller module save the configuration settings to NVRAM Ifpower is removed before you replace an IO controller module the settings can berestored from NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down and select ldquocontroller maintenancerdquo
3 Select ldquosave NVRAM to disksrdquo and press Return
4 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
512 Removing an IO Controller Module1 Keep the array powered on and make sure that the connected hosts are inactive
Note ndash Most users who have multiple host connections between the two controllersuse multi-pathing software to manage them If multi-pathing software andconnectivity is not possible one alternative is to power off the array and discontinueall host IO until the replacement is completed and the array is powered on
2 Write down the cabling configuration for the controller-to-host connection andexpansion unit connections so that you can reconnect the cables correctly with thenew IO controller module See FIGURE 5-1

513 Installing an IO Controller Module1 Keep the array powered on Gently slide the IO controller module into the unit
until it clicks and is seated in the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray and that you keep the power on If you power off and then replace themodule you will have to continue with additional steps Refer to ldquoIO ControllerReplacement for a Single-Controller or Powered-Off Arrayrdquo on page 5-5
2 Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

515 IO Controller Replacement for a Single-Controller or Powered-Off ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo then select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained thisfeature is especially important in a Sun Cluster environment to maintain thesame disk device names in a cluster
3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
52 Replacing IO Expansion ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
All IO expansion modules are hot-serviceable Hot-serviceable means that themodule can be replaced while the array and hosts are powered on but the connectedhosts must be inactive
Chapter 5 FC Module FRUs 5-5
Caution ndash When you replace an IO expansion module the connected hosts mustbe inactive during the replacement procedure
521 Removing the IO Expansion Module1 Keep the array powered on and be sure that the connected hosts are inactive
during this procedure
2 Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the IO expansion module
522 Installing the IO Expansion Module1 Keep the array powered on and be sure that the connected hosts are inactive
during this procedure
2 Slide the IO expansion module into the chassis until the module is firmly seatedin the backplane and the modulersquos front panel is flush with the chassis

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

ldquoConverting an FC JBOD to an FC RAID Arrayrdquo on page 5-12
51 Replacing an IO Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4 The IOcontroller modules are hot-serviceable Hot-serviceable means that the module canbe replaced while the array and hosts are powered on but the connected hosts mustbe inactive
5-1
Caution ndash Connected hosts must be inactive during this replacement procedure
511 Saving the Configuration Settings to NVRAMBefore replacing a controller module save the configuration settings to NVRAM Ifpower is removed before you replace an IO controller module the settings can berestored from NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down and select ldquocontroller maintenancerdquo
3 Select ldquosave NVRAM to disksrdquo and press Return
4 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
512 Removing an IO Controller Module1 Keep the array powered on and make sure that the connected hosts are inactive
Note ndash Most users who have multiple host connections between the two controllersuse multi-pathing software to manage them If multi-pathing software andconnectivity is not possible one alternative is to power off the array and discontinueall host IO until the replacement is completed and the array is powered on
2 Write down the cabling configuration for the controller-to-host connection andexpansion unit connections so that you can reconnect the cables correctly with thenew IO controller module See FIGURE 5-1
3 Remove all cables from the IO controller module

513 Installing an IO Controller Module1 Keep the array powered on Gently slide the IO controller module into the unit
until it clicks and is seated in the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray and that you keep the power on If you power off and then replace themodule you will have to continue with additional steps Refer to ldquoIO ControllerReplacement for a Single-Controller or Powered-Off Arrayrdquo on page 5-5
2 Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

612 Removing a SCSI Controller Module1 Keep the array powered on
2 Turn the thumbscrews on the left and right sides of the controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the controller module
613 Installing a SCSI Controller Module1 Keep the array powered on Gently slide the controller module into the unit until
it clicks and is seated in the backplane
6-2 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
2 Turn the thumbscrews on the left and right sides of the controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units

18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

ldquoInstalling Small Form-Factor Pluggable Transceiversrdquo on page 5-8
ldquoInstalling a RAIDExpansion Chassis FRUrdquo on page 5-9
ldquoConverting an FC JBOD to an FC RAID Arrayrdquo on page 5-12
51 Replacing an IO Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4 The IOcontroller modules are hot-serviceable Hot-serviceable means that the module canbe replaced while the array and hosts are powered on but the connected hosts mustbe inactive
5-1
Caution ndash Connected hosts must be inactive during this replacement procedure
511 Saving the Configuration Settings to NVRAMBefore replacing a controller module save the configuration settings to NVRAM Ifpower is removed before you replace an IO controller module the settings can berestored from NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down and select ldquocontroller maintenancerdquo
3 Select ldquosave NVRAM to disksrdquo and press Return
4 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
512 Removing an IO Controller Module1 Keep the array powered on and make sure that the connected hosts are inactive
Note ndash Most users who have multiple host connections between the two controllersuse multi-pathing software to manage them If multi-pathing software andconnectivity is not possible one alternative is to power off the array and discontinueall host IO until the replacement is completed and the array is powered on
2 Write down the cabling configuration for the controller-to-host connection andexpansion unit connections so that you can reconnect the cables correctly with thenew IO controller module See FIGURE 5-1
3 Remove all cables from the IO controller module
4 Turn the thumbscrews on the left and right sides of the IO controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
5 Hold the thumbscrews and pull out the IO controller module

Chapter 5 FC Module FRUs 5-3
513 Installing an IO Controller Module1 Keep the array powered on Gently slide the IO controller module into the unit
until it clicks and is seated in the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray and that you keep the power on If you power off and then replace themodule you will have to continue with additional steps Refer to ldquoIO ControllerReplacement for a Single-Controller or Powered-Off Arrayrdquo on page 5-5
2 Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo
5-4 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
515 IO Controller Replacement for a Single-Controller or Powered-Off ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo then select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained thisfeature is especially important in a Sun Cluster environment to maintain thesame disk device names in a cluster
3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
52 Replacing IO Expansion ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
All IO expansion modules are hot-serviceable Hot-serviceable means that themodule can be replaced while the array and hosts are powered on but the connectedhosts must be inactive
Chapter 5 FC Module FRUs 5-5
Caution ndash When you replace an IO expansion module the connected hosts mustbe inactive during the replacement procedure
521 Removing the IO Expansion Module1 Keep the array powered on and be sure that the connected hosts are inactive
during this procedure
2 Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the IO expansion module
522 Installing the IO Expansion Module1 Keep the array powered on and be sure that the connected hosts are inactive
during this procedure
2 Slide the IO expansion module into the chassis until the module is firmly seatedin the backplane and the modulersquos front panel is flush with the chassis
Caution ndash Be sure that the IO expansion module is properly inserted into theguide rails of the array
3 Turn the thumbscrews on the left and right sides of the IO expansion moduleclockwise until the thumbscrews are finger-tight to secure the module
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
If you power on the expansion unit hear an audible alarm and see a blinking amberEvent light on the front of your array the new controller has a different version ofSES or PLD firmware than the other IO controller in your array To solve thismismatch refer to ldquoSES Firmware Update Sometimes Required with IO ControllerModule Replacementsrdquo on page 5-7
Note ndash The beep code that identifies an SES or PLD firmware match is the repeatingMorse code letter ldquoRrdquo dot dash dot

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5
FIGURE 5-2 Six SFP Ports on an IO Controller Module
Each Fibre Channel IO expansion module has two SFP ports These ports arelabeled Loop A or Loop B

56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure

18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

ldquoConverting an FC JBOD to an FC RAID Arrayrdquo on page 5-12
51 Replacing an IO Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4 The IOcontroller modules are hot-serviceable Hot-serviceable means that the module canbe replaced while the array and hosts are powered on but the connected hosts mustbe inactive
5-1
Caution ndash Connected hosts must be inactive during this replacement procedure
511 Saving the Configuration Settings to NVRAMBefore replacing a controller module save the configuration settings to NVRAM Ifpower is removed before you replace an IO controller module the settings can berestored from NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down and select ldquocontroller maintenancerdquo
3 Select ldquosave NVRAM to disksrdquo and press Return
4 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
512 Removing an IO Controller Module1 Keep the array powered on and make sure that the connected hosts are inactive
Note ndash Most users who have multiple host connections between the two controllersuse multi-pathing software to manage them If multi-pathing software andconnectivity is not possible one alternative is to power off the array and discontinueall host IO until the replacement is completed and the array is powered on
2 Write down the cabling configuration for the controller-to-host connection andexpansion unit connections so that you can reconnect the cables correctly with thenew IO controller module See FIGURE 5-1
3 Remove all cables from the IO controller module
4 Turn the thumbscrews on the left and right sides of the IO controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
5 Hold the thumbscrews and pull out the IO controller module

Chapter 5 FC Module FRUs 5-3
513 Installing an IO Controller Module1 Keep the array powered on Gently slide the IO controller module into the unit
until it clicks and is seated in the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray and that you keep the power on If you power off and then replace themodule you will have to continue with additional steps Refer to ldquoIO ControllerReplacement for a Single-Controller or Powered-Off Arrayrdquo on page 5-5
2 Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
3 Reconnect the original cables to the new IO controller module
Caution ndash You must connect the hosts to the correct host channels on the IOcontroller module or your configuration will not work correctly
514 Converting a Dual-Controller Array to a SingleController ArrayIf you convert a dual-controller unit into a single-controller unit the SSCS softwaredoes not automatically recognize the change and reports that the SES and batteryboard from the removed controller are failed or not present
If you are running SSCS software and want to avoid this message follow the steps inthe chapter titled ldquoMaintaining the Arrayrdquo in the Sun StorEdge 3000 FamilyConfiguration Service Userrsquos Guide The section containing the instructions is entitledldquoConverting a Dual Controller Array to a Single Controller Arrayrdquo

a From the Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo then select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained thisfeature is especially important in a Sun Cluster environment to maintain thesame disk device names in a cluster
3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
52 Replacing IO Expansion ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
All IO expansion modules are hot-serviceable Hot-serviceable means that themodule can be replaced while the array and hosts are powered on but the connectedhosts must be inactive
Chapter 5 FC Module FRUs 5-5
Caution ndash When you replace an IO expansion module the connected hosts mustbe inactive during the replacement procedure
521 Removing the IO Expansion Module1 Keep the array powered on and be sure that the connected hosts are inactive
during this procedure
2 Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the IO expansion module
522 Installing the IO Expansion Module1 Keep the array powered on and be sure that the connected hosts are inactive
during this procedure
2 Slide the IO expansion module into the chassis until the module is firmly seatedin the backplane and the modulersquos front panel is flush with the chassis
Caution ndash Be sure that the IO expansion module is properly inserted into theguide rails of the array
3 Turn the thumbscrews on the left and right sides of the IO expansion moduleclockwise until the thumbscrews are finger-tight to secure the module
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
If you power on the expansion unit hear an audible alarm and see a blinking amberEvent light on the front of your array the new controller has a different version ofSES or PLD firmware than the other IO controller in your array To solve thismismatch refer to ldquoSES Firmware Update Sometimes Required with IO ControllerModule Replacementsrdquo on page 5-7
Note ndash The beep code that identifies an SES or PLD firmware match is the repeatingMorse code letter ldquoRrdquo dot dash dot

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo

b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units

Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

18 If you are creating a dual-controller RAID array perform the following steps withthe firmware application to ensure compatibility
5-18 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a To check the controller firmware version of each module perform these steps
Remove one IO controller module so that only one IO controller moduleremains in the array
Maintain a serial port connection to a terminal or workstation as described in step10
In the firmware application select ldquoview system Informationrdquo and record theFirmware Version
Insert the second IO controller module remove the first module and selectldquoview system Informationrdquo to record the Firmware Version of the second module
To check that you have the latest firmware go to
httpsunsolvesuncom
and select Patch Portal and then browse in the Sun Alert Patch Report or checkthe Sun StorEdge 3510 FC Release Notes for firmware patch information
b Check the number on each IO controller module faceplate where there is afour-digit number such as 0350 or 0450
Both IO controller modules must have the same first two digits which representa SESPLD firmware level in the module If the two modules have two differentnumbers for example 03 and 04 you must upgrade one IO controller module tothe higher level or both modules to the latest SESPLD level For moreinformation refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
c If the firmware versions of the two IO controller modules do not matchdownload the latest firmware to each IO controller module to ensure that theyhave the latest firmware and the same firmware
To download new versions of controller firmware disk drive firmware orSESPLD firmware use one of the following tools and check the Sun StorEdge3510 Release Notes or Sun Solve for the latest firmware patch

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array

b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

513 Installing an IO Controller Module1 Keep the array powered on Gently slide the IO controller module into the unit
until it clicks and is seated in the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray and that you keep the power on If you power off and then replace themodule you will have to continue with additional steps Refer to ldquoIO ControllerReplacement for a Single-Controller or Powered-Off Arrayrdquo on page 5-5
2 Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
If you power on your array hear an audible alarm and see a blinking amber Eventlight on the front of your array the new controller has a different version of SESfirmware or its associated PLD code than the other IO controller in your array Tosolve this mismatch refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

515 IO Controller Replacement for a Single-Controller or Powered-Off ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo then select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained thisfeature is especially important in a Sun Cluster environment to maintain thesame disk device names in a cluster
3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
52 Replacing IO Expansion ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
All IO expansion modules are hot-serviceable Hot-serviceable means that themodule can be replaced while the array and hosts are powered on but the connectedhosts must be inactive
Chapter 5 FC Module FRUs 5-5
Caution ndash When you replace an IO expansion module the connected hosts mustbe inactive during the replacement procedure
521 Removing the IO Expansion Module1 Keep the array powered on and be sure that the connected hosts are inactive
during this procedure
2 Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the IO expansion module
522 Installing the IO Expansion Module1 Keep the array powered on and be sure that the connected hosts are inactive
during this procedure
2 Slide the IO expansion module into the chassis until the module is firmly seatedin the backplane and the modulersquos front panel is flush with the chassis
Caution ndash Be sure that the IO expansion module is properly inserted into theguide rails of the array
3 Turn the thumbscrews on the left and right sides of the IO expansion moduleclockwise until the thumbscrews are finger-tight to secure the module
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
If you power on the expansion unit hear an audible alarm and see a blinking amberEvent light on the front of your array the new controller has a different version ofSES or PLD firmware than the other IO controller in your array To solve thismismatch refer to ldquoSES Firmware Update Sometimes Required with IO ControllerModule Replacementsrdquo on page 5-7
Note ndash The beep code that identifies an SES or PLD firmware match is the repeatingMorse code letter ldquoRrdquo dot dash dot

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5

Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly

6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo

a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade

661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

53 SES Firmware Update SometimesRequired with IO Controller ModuleReplacementsPeriodically firmware upgrades are made available as patches that you candownload from SunSolvetrade Online located at
httpsunsolvesuncom
The Sun StorEdge 3510 FC array patch contains the most current version of thecontroller SES and PLD firmware
SunSolve has extensive search capabilities that can help you find this patch as wellas regular patch reports and alerts to let you know when firmware upgrades andrelated patches become available In addition SunSolve provides reports about bugsthat have been fixed in patch updates
Each patch includes an associated Readme text file that provides detailedinstructions about how to download and install that patch But generally speakingall firmware downloads follow the same steps
Locating the patch on SunSolve that contains the firmware upgrade you want
Downloading the patch to a location on your network
Using your array software (SSCS or sscli(1M) or array firmware in some casesto ldquoflashrdquo the firmware to the device it updates
Refer to the Release Notes for your array for latest patch available for your array atthe time of release
If you power on the expansion unit or array hear an audible alarm and see ablinking amber Event light on the front of the arrayunit the new IO expansionmodule or controller module has a different version of SES firmware or PLDfirmware from that of the other IO module in the unitarray To resolve this issueyou need to download new SES firmware This can be done using Sun StorEdgeConfiguration Service software or the command line interface (CLI) for your array
If you have not installed this software you need to install it from the CD that waspackaged with your array
Use the CLI commands show ses and show events to see what error condition iscausing the alarms If the error message indicates a PLD firmware mismatch it maybe because your SES firmware has not yet been upgraded Upgrading your SESfirmware usually resolves any apparent PLD mismatch
Chapter 5 FC Module FRUs 5-7
Refer to the Sun StorEdge 3000 Family Configuration Service Users Guide for yourarray to see instructions for ldquoflashingrdquo the upgraded firmware to the appropriatedevice or refer to the sccli(1M) man page for instructions on performing the sameoperation using the CLI
Caution ndash Follow the upgrade instructions in the patch README file with greatcare to download and install firmware correctly If the wrong firmware is installedor the firmware is installed on the wrong device your controller may be renderedinoperable Always be sure to upgrade your SES firmware first before trying todetermine if you need a PLD upgrade
54 Installing Small Form-Factor PluggableTransceiversFibre Channel arrays use small form-factor (SFP) transceivers to attach the array tohosts and expansion units
Each Fibre Channel IO controller module has six SFP ports as shown in the lowerrow of ports in FIGURE 5-2 These ports are labeled FC0 through FC5
FIGURE 5-2 Six SFP Ports on an IO Controller Module
Each Fibre Channel IO expansion module has two SFP ports These ports arelabeled Loop A or Loop B

19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo

a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD

6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

7 Insert additional SFPs into the new IO controller module as needed
8 Install an IO controller module into the top slot with the following steps
a Gently slide the IO controller module into the unit until it clicks and is seatedin the backplane
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
b Turn the thumbscrews on the left and right sides of the IO controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
9 Repeat steps 4 and 5 to remove the IO module in the lower slot and repeat step 6to install a second IO controller module if you want to create a dual-controllerRAID array
10 Power on the array
11 Print or locate chapters 4 and 5 of the Sun StorEdge Installation Operation and ServiceManual for the array to use for the remainder of this procedure
12 Connect the new RAID array to a terminal emulation program or workstationthrough its serial port
For information on how to connect to the serial port refer to section 47 Configuringa COM Port to Connect to a RAID Array in the installation manual
On a Solaris system use the tip command to access the array locally

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

61 Replacing a SCSI Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
The controller modules are hot-swappable
611 Saving the Configuration Settings to NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set Before replacing a controller module save theconfiguration settings to NVRAM If power is removed before you replace a IOcontroller module the settings can be restored from NVRAM
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down select ldquocontroller maintenancerdquo and thenselect ldquosave NVRAM to disksrdquo and press Return
3 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
612 Removing a SCSI Controller Module1 Keep the array powered on
2 Turn the thumbscrews on the left and right sides of the controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the controller module
613 Installing a SCSI Controller Module1 Keep the array powered on Gently slide the controller module into the unit until
it clicks and is seated in the backplane
6-2 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
2 Turn the thumbscrews on the left and right sides of the controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)

3 Ensure that all SCSI cables attached to the IO module are labeled clearly Thenremove all SCSI cables attached to the IO module
Caution ndash The IO module offers resistance when you remove it from the chassisbackplane When unseating the module from the chassis check that you do not bendbackwards the ERROR LED mounted on the module
4 Turn the thumbscrews on the left and right sides of an IO modulecounterclockwise until the thumbscrews are disengaged from the chassis
5 Hold the thumbscrews and using a slight downward pressure pull evenly on thescrews to disengage the IO module
623 Installing a SCSI IO Module1 With the power still off slide the IO module into the chassis far enough to
engage the thumbscrews
Caution ndash Be sure that the IO module is properly inserted into the guide rails
2 Turn the thumbscrews on the left and right sides of the IO module clockwise astight as possible without using a screwdriver Then push firmly with a singlefirm two-handed push which should move the module about 1 cm
3 Tighten the thumbscrews again Then push firmly with a single firm two-handedpush Tighten the thumbscrews again until finger-tight
Note ndash An improperly seated IO module commonly causes SCSI channel errors
4 Reinstall all SCSI cables in their original positions
5 Power on both power supply modules

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo

17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

56 Converting an FC JBOD to an FC RAIDArrayYou can convert an FC JBOD (or expansion unit) to a single- or dual-controller FCRAID array by performing the following procedure
Components required for this conversion are
An FC JBOD An FC IO controller module (two modules for a dual-controller array) Additional SFPs as needed A serial null modem cable for initial configuration of the RAID array Ethernet cable(s) for network access (one for each IO controller module) Sun StorEdge Operation Installation and Service Manual for the array Sun StorEdge Configuration Service Userrsquos Guide (if Configuration Service is used to
manage and monitor Sun StorEdge 3000 Family products)
5-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

Note ndash If you do not have the required cables consult your sales representative toobtain them
1 If you have data on the JBOD drives be sure to back up the data onto the networkor onto another array prior to the conversion of the JBOD to a RAID array
Caution ndash The data on the drives of a JBOD will not be accessible after the JBOD isconverted to a RAID array Therefore it is essential that you back up the JBOD dataonto another storage device prior to converting the JBOD to a RAID array
Note ndash You must use a tool within Solaris or an external software package toperform the data backup function The firmware software and CLI provided withthe Sun StorEdge 3510 FC array do not have backup functions for data
2 If you use Sun StorEdge Configuration Service (SSCS) to monitor your arrays andJBODs stop the sscs daemon and close the console
Note ndash When you disconnect the JBOD from the host the JBOD drives will appearas failed drives in SSCS To remove the failed drive entries you need to stop thedaemon remove the JBOD and restart the daemon
3 To convert the JBOD to a RAID array power off the JBOD
4 Remove all cables connected to the JBOD IO expansion module(s) which will bereplaced by IO controller module(s)
5 Remove the top IO expansion module with the following steps
a Turn the thumbscrews on the left and right sides of an IO expansion modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the IO expansion module
c To remove an SFP make sure no cable is connected to it and then slide it outfrom the port
Each IO expansion module has one SFP which can be re-used and inserted intothe new IO controller module
Chapter 5 FC Module FRUs 5-13
6 Insert the SFP from step 5c into the new IO controller module
Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits
Host port FC0 Drive port FC2 Host port FC4
Host port FC1 Drive port FC3 Host port FC5

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array

a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

Slide the single-end of the SFP into an empty port so that it connects firmly with thechassis
See FIGURE 5-5 and FIGURE 5-6 for recommended SFP locations in IO controllermodules
Note ndash IO controller module FRUs do not have any SFPs the SFPs must beordered separately The IO controller module X-Option includes two SFPs anEthernet cable and a serial cable
In a dual-controller array the recommended configuration is SFPs plugged into thefollowing ports namely into one port out of two ports in each pair of host and driveports
The upper IO controller module with SFPs in the FC0 FC2 and FC4 ports
The lower IO controller module with SFPs in the FC1 FC3 and FC5 ports
This configuration provides connections to all four host channels as well as to bothdrive channels
FIGURE 5-5 Recommended Dual-Controller SFP Placement
In a single-controller array SFPs are usually plugged into FC0 FC1 FC4 and FC5No SFPs are plugged into the drive channels This configuration is appropriate forconnecting to up to four hosts or fibre switches with no connection to expansionunits

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo

a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13

Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

18 If you are creating a dual-controller RAID array perform the following steps withthe firmware application to ensure compatibility
5-18 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a To check the controller firmware version of each module perform these steps
Remove one IO controller module so that only one IO controller moduleremains in the array
Maintain a serial port connection to a terminal or workstation as described in step10
In the firmware application select ldquoview system Informationrdquo and record theFirmware Version
Insert the second IO controller module remove the first module and selectldquoview system Informationrdquo to record the Firmware Version of the second module
To check that you have the latest firmware go to
httpsunsolvesuncom
and select Patch Portal and then browse in the Sun Alert Patch Report or checkthe Sun StorEdge 3510 FC Release Notes for firmware patch information
b Check the number on each IO controller module faceplate where there is afour-digit number such as 0350 or 0450
Both IO controller modules must have the same first two digits which representa SESPLD firmware level in the module If the two modules have two differentnumbers for example 03 and 04 you must upgrade one IO controller module tothe higher level or both modules to the latest SESPLD level For moreinformation refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
c If the firmware versions of the two IO controller modules do not matchdownload the latest firmware to each IO controller module to ensure that theyhave the latest firmware and the same firmware
To download new versions of controller firmware disk drive firmware orSESPLD firmware use one of the following tools and check the Sun StorEdge3510 Release Notes or Sun Solve for the latest firmware patch

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate

19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required

Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

a To check the controller firmware version of each module perform these steps
Remove one IO controller module so that only one IO controller moduleremains in the array
Maintain a serial port connection to a terminal or workstation as described in step10
In the firmware application select ldquoview system Informationrdquo and record theFirmware Version
Insert the second IO controller module remove the first module and selectldquoview system Informationrdquo to record the Firmware Version of the second module
To check that you have the latest firmware go to
httpsunsolvesuncom
and select Patch Portal and then browse in the Sun Alert Patch Report or checkthe Sun StorEdge 3510 FC Release Notes for firmware patch information
b Check the number on each IO controller module faceplate where there is afour-digit number such as 0350 or 0450
Both IO controller modules must have the same first two digits which representa SESPLD firmware level in the module If the two modules have two differentnumbers for example 03 and 04 you must upgrade one IO controller module tothe higher level or both modules to the latest SESPLD level For moreinformation refer to ldquoSES Firmware Update Sometimes Required with IOController Module Replacementsrdquo on page 5-7
c If the firmware versions of the two IO controller modules do not matchdownload the latest firmware to each IO controller module to ensure that theyhave the latest firmware and the same firmware
To download new versions of controller firmware disk drive firmware orSESPLD firmware use one of the following tools and check the Sun StorEdge3510 Release Notes or Sun Solve for the latest firmware patch

Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
2 Turn the thumbscrews on the left and right sides of the controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)

d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

6-1
61 Replacing a SCSI Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
The controller modules are hot-swappable
611 Saving the Configuration Settings to NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set Before replacing a controller module save theconfiguration settings to NVRAM If power is removed before you replace a IOcontroller module the settings can be restored from NVRAM
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down select ldquocontroller maintenancerdquo and thenselect ldquosave NVRAM to disksrdquo and press Return
3 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
612 Removing a SCSI Controller Module1 Keep the array powered on
2 Turn the thumbscrews on the left and right sides of the controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the controller module
613 Installing a SCSI Controller Module1 Keep the array powered on Gently slide the controller module into the unit until
it clicks and is seated in the backplane
6-2 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
2 Turn the thumbscrews on the left and right sides of the controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster

3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)
6-4 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
3 Ensure that all SCSI cables attached to the IO module are labeled clearly Thenremove all SCSI cables attached to the IO module
Caution ndash The IO module offers resistance when you remove it from the chassisbackplane When unseating the module from the chassis check that you do not bendbackwards the ERROR LED mounted on the module
4 Turn the thumbscrews on the left and right sides of an IO modulecounterclockwise until the thumbscrews are disengaged from the chassis
5 Hold the thumbscrews and using a slight downward pressure pull evenly on thescrews to disengage the IO module
623 Installing a SCSI IO Module1 With the power still off slide the IO module into the chassis far enough to
engage the thumbscrews
Caution ndash Be sure that the IO module is properly inserted into the guide rails
2 Turn the thumbscrews on the left and right sides of the IO module clockwise astight as possible without using a screwdriver Then push firmly with a singlefirm two-handed push which should move the module about 1 cm
3 Tighten the thumbscrews again Then push firmly with a single firm two-handedpush Tighten the thumbscrews again until finger-tight
Note ndash An improperly seated IO module commonly causes SCSI channel errors
4 Reinstall all SCSI cables in their original positions
5 Power on both power supply modules
Chapter 6 SCSI Module FRUs 6-5
63 Replacing the SCSI Terminator ModuleBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
631 Removing the SCSI Terminator Module1 Power off both power supply modules on the array
Although the terminator module is technically hot-swappable most users power offthe array because the procedure requires that you will be removing and reinsertingthree modules during the procedure
Caution ndash Connected hosts must be inactive during this replacement procedure
2 Remove all serial and Ethernet cables connected to the controller modules
3 Remove both controller modules
a Turn the thumbscrews on the left and right sides of each controller modulecounterclockwise until the thumbscrews are disengaged from the chassis

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

61 Replacing a SCSI Controller ModuleBe sure to follow the ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
The controller modules are hot-swappable
611 Saving the Configuration Settings to NVRAM
Caution ndash If you power off the array and replace a controller module thereplacement controller could become the primary controller and overwrite anyconfiguration settings previously set Before replacing a controller module save theconfiguration settings to NVRAM If power is removed before you replace a IOcontroller module the settings can be restored from NVRAM
1 From the firmware application Main Menu choose ldquosystem Functionsrdquo
2 Use the arrow keys to scroll down select ldquocontroller maintenancerdquo and thenselect ldquosave NVRAM to disksrdquo and press Return
3 Choose Yes to confirm A message informs you that NVRAM information hasbeen successfully saved
612 Removing a SCSI Controller Module1 Keep the array powered on
2 Turn the thumbscrews on the left and right sides of the controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
3 Hold the thumbscrews and pull out the controller module
613 Installing a SCSI Controller Module1 Keep the array powered on Gently slide the controller module into the unit until
it clicks and is seated in the backplane
6-2 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash Be sure that the module is properly inserted into the guide rails of thearray
2 Turn the thumbscrews on the left and right sides of the controller moduleclockwise until they are finger-tight to secure the module and to make themodulersquos front panel flush with the chassis
Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
The new controller automatically becomes the secondary controller
614 Replacing a Single-Controller Array or PoweredOff ArrayIf the array was powered off during the controller replacement or if you replaced acontroller in a single-controller configuration perform the following importantsteps
1 Restore configuration settings from NVRAM if the new controller replaced an oldcontroller
a From the firmware Main Menu select ldquosystem Functionsrdquo select ldquoControllermaintenancerdquo and press Return
b Select ldquoRestore NVRAM from disksrdquo and press Return Press Yes to confirm
2 Set the parameter called the ldquoController Unique Identifierrdquo to the correct value
a From the firmware Main Menu select ldquoview and edit Configurationparametersrdquo select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return Type the value 0 (to automatically read the chassisserial number from the midplane) or type the hex value for the original serialnumber of the chassis (used when the midplane has been replaced)
The Controller Unique Identifier is used to create Ethernet addresses andworldwide names The value 0 is immediately replaced with the hex value of thechassis serial number A nonzero value should be specified only if the chassis hasbeen replaced but the original chassis serial number must be retained this featureis especially important in a Sun Cluster environment to maintain the same diskdevice names in a cluster
Chapter 6 SCSI Module FRUs 6-3
3 To implement the revised configuration settings from step 1 or step 2 selectldquosystem Functionsrdquo from the Main Menu select ldquoReset controllerrdquo and pressReturn
62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module
Caution ndash Connected hosts must be inactive during this replacement procedure
1 Power off both power supply modules on the array
2 Write down the bus configuration (dual-bus or single-bus configuration)
6-4 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
3 Ensure that all SCSI cables attached to the IO module are labeled clearly Thenremove all SCSI cables attached to the IO module
Caution ndash The IO module offers resistance when you remove it from the chassisbackplane When unseating the module from the chassis check that you do not bendbackwards the ERROR LED mounted on the module
4 Turn the thumbscrews on the left and right sides of an IO modulecounterclockwise until the thumbscrews are disengaged from the chassis
5 Hold the thumbscrews and using a slight downward pressure pull evenly on thescrews to disengage the IO module
623 Installing a SCSI IO Module1 With the power still off slide the IO module into the chassis far enough to
engage the thumbscrews
Caution ndash Be sure that the IO module is properly inserted into the guide rails
2 Turn the thumbscrews on the left and right sides of the IO module clockwise astight as possible without using a screwdriver Then push firmly with a singlefirm two-handed push which should move the module about 1 cm
3 Tighten the thumbscrews again Then push firmly with a single firm two-handedpush Tighten the thumbscrews again until finger-tight
Note ndash An improperly seated IO module commonly causes SCSI channel errors
4 Reinstall all SCSI cables in their original positions
5 Power on both power supply modules
Chapter 6 SCSI Module FRUs 6-5
63 Replacing the SCSI Terminator ModuleBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
631 Removing the SCSI Terminator Module1 Power off both power supply modules on the array
Although the terminator module is technically hot-swappable most users power offthe array because the procedure requires that you will be removing and reinsertingthree modules during the procedure
Caution ndash Connected hosts must be inactive during this replacement procedure
2 Remove all serial and Ethernet cables connected to the controller modules
3 Remove both controller modules
a Turn the thumbscrews on the left and right sides of each controller modulecounterclockwise until the thumbscrews are disengaged from the chassis
b Hold the thumbscrews and pull out the controller module
4 Hold the terminator module by the front edges and pull it out of the chassis

Note ndash To ensure that a thumbscrew is finger-tight tighten it with a screwdriverand then loosen the thumbscrew counterclockwise a quarter-turn
65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)

661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration

62 Replacing SCSI IO ModulesBe sure to follow ldquoStatic Electricity and Other Precautionsrdquo on page 1-4
Caution ndash The SCSI IO modules are hot-serviceable only if you disable thePeriodic Drive Check Time parameter through the firmware application this is notthe preferred procedure Hot-serviceable means that the module can be replaced whilethe array and hosts are powered on but the connected hosts must be inactive
621 Installing Gaskets If NeededPrior to installing the IO module check to see if there is a 14-inch thin gasket onthe top inside edge of the IO module slot on the chassis
If the gasket in on that edge do not use the gasket provided with the IO moduleFRU
If there is no gasket on the top inside edge of the IO module slot install theenclosed gasket as follows
1 Remove the plastic white backing on the back of the gasket
2 Attach the adhesive side of the gasket to the top inside edge of the IO modulefaceplate This will look identical to gasket already on the bottom inside edge ofthe IO module faceplate
622 Removing the SCSI IO Module

65 Installing a RAIDExpansion ChassisFRUThe Sun StorEdge 3310 SCSI array box FRU includes a chassis its drive midplaneand its backplane This product is ordered to replace a box that has been damaged orwhose midplane or backplane has been damaged
To make a fully functional array you need to add the following parts from thereplaced array
Drive modules
Two power supplyfan modules
Two EMU modules
One or two JBOD IO modules (for an expansion unit or JBOD)
One or two RAID IO modules (for a RAID array)
One or two RAID controllers (for a RAID array)
One terminator module
To install the individual modules use the replacement instructions provided in thisguide
Chapter 6 SCSI Module FRUs 6-9
To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly

6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet

19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

To configure the array refer to the installation manual for your array located onyour Sun StorEdge 3000 Family Documentation CD
To replace the chassis frame of an existing RAID array or expansion unit performthe following steps
1 Connect to the firmware application via the serial interface (tip for SolarisLinux)or via telnet
Caution ndash Connected hosts must be inactive during this replacement procedure
2 If the defective array is a RAID array
From the Main Menu select ldquoview and edit Configuration parametersrdquo then selectldquoController Parametersrdquo
Write down the Controller Unique Identifier (hex) - value
3 Power off both power supply modules on the defective array
4 Ensure all SCSI cables attached to the IO module are labeled clearly
5 Write down the defective arrays cabling configuration
6 Remove all SCSI cables attached to the IO module
7 If the defective array is a RAID array remove all serial and Ethernet cablesconnected to the RAID controllers
8 Label each disk drive with its disk slot position in the array
9 Remove the RAID controllers (if applicable) terminator board (if applicable) IOmodule(s) EMUs power supply modules and disk drives from the defectivearray
10 Remove the defective chassis
11 Obtain the replacement chassis
12 Re-install all previously removed modules in their original positions into thereplacement array
13 Re-install all SCSI serial Ethernet and power cables in their original positions
14 Power on both power supply modules on the replacement array
15 If the replacement array is an expansion unit or JBOD refer to your installationmanual to configure it
16 If the replacement chassis is a RAID array proceed with the following steps
6-10 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
a Connect to the array console menu interface via the serial interface (tip forSolarisLinux) or via telnet
b From the Main Menu select ldquoview and edit Configuration parametersrdquo thenldquoController Parametersrdquo
c Select Controller Unique Identifier (hex)
17 If this array is being used by clustered hosts or for any other reason its attachedhosts require that their Device IDs remaining consistent perform these steps
a Set Controller Unique Identifier (hex) to the value you wrote down in step 2
b Reset the RAID Controllers From the Main Menu select ldquosystem Functionsrdquothen ldquoReset controllerrdquo Confirm Yes when prompted
c Proceed with step 19
18 If this array is NOT being used by clustered hosts perform these steps
a On the firmware main menu select ldquoview and edit Configuration parametersrdquothen select ldquoController Parametersrdquo and press Return
b From the Controller Parameters menu select ldquoController Unique Identifierlthexgtrdquo and press Return
c Type in the value 0 (to automatically read the chassis serial number from themidplane)
Chapter 6 SCSI Module FRUs 6-11
The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)
6-12 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

The value 0 is immediately replaced with the hex value of the chassis serialnumber
d To implement the revised parameter value select ldquosystem Functionsrdquo on theMain Menu select ldquoReset Controllerrdquo and press Return
19 Connect the array to hosts according to the configuration identified in steps 4and 5 The chassis replacement is now complete
66 Special JBOD Usage With ExternalTerminatorsThe external terminator is necessary only during certain maintenance tasksperformed with a Sun StorEdge 3310 SCSI JBOD dual bus configuration which isconnected directly to multiple servers in a clustering environment (most often theSun Cluster environment) With many maintenance tasks you remove a failed oroutdated part and replace it immediately this is standard procedure
However if you have an unusual situation and need to remove a host connectionfrom the JBOD for a prolonged period you might need to preserve the other hostconnections and activity on the JBOD
The Sun SCSI LVDMSE external terminator is part number XTA-3310-SC-TERM(595-6750-01)

661 External Terminators for Special Dual-Bus JBODMaintenanceIf you have JBOD IO modules part number 370-5396-0250 or higher use thisinformation
Note ndash This new IO module supports both single-initiator and multi-initiator dual-bus configurations The older IO module supports only single-initiator dual-busconfigurations
If you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher see ldquoOlder JBOD Dual-Bus Configurationsrdquo on page 6-14
To preserve all original SCSI IDs and correct termination on a dual-bus JBOD in acluster environment insert an external terminator in all cases where a SCSI portbecomes empty that was not empty in the original configuration This maintains theSCSI drive IDs for the active host connections For an example of two removedcables and two inserted terminators see FIGURE 6-3
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI drive IDs are 8 to 13
FIGURE 6-3 Two Terminators for Two Cables Which Have Been Removed in a Dual-BusConfiguration
Chapter 6 SCSI Module FRUs 6-13
Caution ndash SCSI IDs are based on the cabling of the array when the array is poweredup If you are removing host connections from a dual-host dual-bus multi-initiatorconfiguration use terminators to preserve the existing SCSI ID assignments (as wellas the termination on the bottom SCSI ports)
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 Insert the external terminator into the empty SCSI port on the array
The external terminator preserves the original SCSI IDs
4 Resume host IO activity on the remaining host(s)
662 Older JBOD Dual-Bus ConfigurationsIf you have earlier IO modules and do not have JBOD IO modules part number370-5396-0250 or higher use the information in this section
Note ndash The older IO modules only supported single-initiator dual-busconfigurations
In a dual-bus configuration the SCSI IDs change according to the termination on theSCSI ports If your original configuration has both SCSI ports connected on a busconnected to host(s) the SCSI IDs are 0 to 5 If only the bottom port is connected toa host the SCSI IDs are 8 to 15 To preserve all original SCSI IDs and correcttermination on a dual bus JBOD in a cluster environment insert an externalterminator in all cases where a top SCSI port is empty but was not empty in theoriginal configuration
Note ndash As a general rule external terminators are necessary in JBOD configurations(for JBOD configuration information refer to the Sun StorEdge 3310 SCSI InstallationOperation and Service Manual) The two bottom SCSI ports on the JBOD are typicallyterminated with an HBA host connection or a SCSI jumper cable The upper IOSCSI connectors are autoterminated Single-bus JBOD cabling does not require anexternal terminator at any time only the dual-bus JBOD cabling in the clusterenvironment has the one condition where external terminators are required
6-14 Sun StorEdge 3000 Family FRU Installation Guide bull October 2003
Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration

67 Installing a Filler Panel on a SCSI ArrayThe filler panel FRU is a single metal panel used to cover an empty controllermodule slot on the rear of a Sun StorEdge 3310 SCSI array Most often this occurswhen you wish to remove a controller module and change a dual-controller array toa single-controller array The filler panel protects the interior of the array
To install a filler panel perform the following steps
1 Remove the controller module according to ldquoRemoving a SCSI ControllerModulerdquo on page 6-2
2 Position the filler panel so that it covers the empty slot and the thumbscrewsoverlay the thumbscrew holes
3 Turn the thumbscrews on the left and right sides of the filler panel clockwiseuntil the thumbscrews are finger-tight to secure the panel on the array

Caution ndash In a cluster configuration adding a separate host connection that was notoriginally planned for the array will cause a change in SCSI IDs and therefore losesaccess to data stored under the original SCSI IDs
To keep other host connections operational while one host connection is temporarilyremoved perform the following steps
1 Stop all host IO activity on the host bus where the removal of a cable will occur
2 Disconnect the array from the host SCSI cable of the server that requires themaintenance work from the array
3 In a dual bus configuration if two hosts are connected to one bus and the hostcable to the bottom port of the array is disconnected move the cable of the topport to the bottom port
The moved cable provides termination to the bottom port
4 Insert the external terminator into the empty top SCSI port on the array
The external terminator preserves the original SCSI IDs which are 0 to 5 on each busthat has two host connections established
5 Resume host IO activity on the remaining host(s)
You can have situations in which one or two SCSI cables are temporarily removed froma standard SCSI array configuration
FIGURE 6-4 Example of a SCSI Array Configuration
In each of the four scenarios in FIGURE 6-5 and FIGURE 6-6 a single cable was removedfrom the original configuration shown in FIGURE 6-4 In each of these scenarios oneexternal terminator was required
Note ndash The bottom input ports support only host SCSI connections and do notsupport external terminators
