CHAPTER 1

System Components

The MSA2000 Family 2012sa Modular Smart Array and MSA2000 Drive Enclosure

are high-performance storage solutions that combine outstanding performance with

high reliability, availability, flexibility, and manageability.

Supported configurations include a controller enclosure with or without attached

drive enclosures. A controller enclosure can contain two controllers that interact and

provide failover capability for the data path. The controller enclosure can use SATA

or SAS disk drive modules.

This chapter provides information about the system components, and includes the

following topics:

n “System Management Software” on page 12

n “Hardware Components and LEDs” on page 13


System Management Software

Embedded management software includes a web-browser interface and the

command-line interface described below.

HP StorageWorks MSA2000 Family Storage Management Utility (SMU)

SMU is the primary interface for configuring and managing the system. A web

server resides in each controller module. SMU enables you to manage the system

from a web browser that is properly configured and that can access a controller

module through an Ethernet connection.

Information about using SMU is in its online help and in the reference guide.

Command-Line Interface (CLI)

The embedded CLI enables you to configure and manage the system using

individual commands or command scripts through an out-of-band RS-232 or

Ethernet connection.

Information about using the CLI is in the CLI reference guide.

Table 1-5 Controller LEDs (Back) (Continued)



Controller

module

Cache status Green Blink A Compact Flash flush or cache self-refresh

is in progress. Indicates cache activity.

• If the LED is blinking evenly, a cache

flush is in progress. When a controller

module loses power and write cache is

dirty (contains data that has not been

written to disk), the super-capacitor pack

provides backup power to flush (copy)

data from write cache to Compact Flash

memory. When cache flush is complete,

the cache transitions into self-refresh

mode.

• If the LED is blinking slowly, a cache

flush is in progress. In self-refresh mode,

if primary power is restored before the

backup power is depleted (3–30 minutes,

depending on various factors), the system

boots, finds data preserved in cache, and

writes it to disk. This means the system

can be operational within 30 seconds, and

before the typical host I/O timeout of 60

seconds at which point system failure

would cause host-application failure. If

primary power is restored after the backup

power is depleted, the system boots and

restores data to cache from Compact

Flash, which can take about 90 seconds.

Note: The cache flush and self-refresh

mechanism is an important data protection

feature; essentially four copies of user data

are preserved: one in each controller’s cache

and one in each controller’s Compact Flash.

Controller

module

Host activity Green Off The host ports have no I/O activity.

Blink At least one host port has I/O activity.

Controller

module

Ethernet link status Green Off The Ethernet port is not connected or the

link is down.

On The Ethernet link is up.

Required Tools

The installation procedures in this chapter require the following tools:

n #2 Phillips screwdriver

n Antistatic protection devices


Safety Precautions

For your protection, observe the following safety precautions when setting up your

equipment:

n Install the system in accordance with the local safety codes and regulations at the

facility site. Follow all cautions and instructions marked on the equipment.

n Ensure that the voltage and frequency of your power source match the voltage

and frequency inscribed on the equipment’s electrical rating label.

n Never push objects of any kind through openings in the equipment. Dangerous

voltages may be present. Conductive foreign objects could produce a short circuit

that could cause fire, electric shock, or damage to your equipment.

Note – Do not make mechanical or electrical modifications to the product. The

vendor is not responsible for the safety or regulatory compliance of a modified

product.

Caution – Two people are needed to lift and move the enclosure. Use care to avoid

injury. An enclosure with all drives installed can weigh 65 pounds (29.5 kilograms).

Caution – Electrostatic discharge can damage sensitive components. Be sure you

are properly grounded before touching a static-sensitive component or assembly.

Installing Enclosures Into a Rack

This section describes how to install the enclosures into a standard 19-inch rack

cabinet with a 28 to 36-inch (71.12 to 91.44-cm) depth.

Tip – To help you correctly identify the screws, keep all hardware items in plastic

bags until you are ready to use them.

Preparing the Rack

Before installing enclosures in a rack cabinet, ensure the rack is installed according

to its installation instructions and that the installation complies with local safety

codes.

1. Stabilize the rack as described in its documentation.

2. If the rack has casters, make sure the casters are locked to prevent the rack from

rolling.

3. Remove or open the top front panel and the vented back panel.

Assembling and Installing the Rackmount Bracket Kit

Note – If the rackmount bracket kit you are installing includes assembly

instructions, use them in place of the instructions in this guide.


Figure 2-1 provides a visual overview of the rackmount kit assembly components

and corresponds to the steps that follow.

Use the following procedure and refer to Figure 2-1 to install each enclosure into

the rack.

Note – If the rackmount bracket kit you are installing includes assembly

instructions, use them in place of the instructions in this guide.

When positioning an enclosure in the rack, do not block the air vents at the front or

back of the enclosure.

Caution – If you only have one person to perform the installation, remove the

power and cooling modules and drive modules from an enclosure before

installation, and use the optional nylon front support brackets. If possible, position

the enclosure on top of another device or shelf in the rack to hold the enclosure as

you attach the front brackets.

1. Considering your system configuration and weight distribution in the rack,

determine where you will install each enclosure in the rack.

2. Confirm that you have cables of adequate length to connect to hosts and to power

outlets.

3. (Square-cut European-style racks only) Insert the cage nuts in the corresponding

holes on the front and rear of the rack.

4. (Optional-one person installation) Screw the front support nylon brackets into

position on the rack face using #10-32 x 5/8 screws (two per bracket).

These brackets enable one person to easily position and support the front of the

enclosure in the rack during installation.

5. Attach the side brackets to each side of the enclosure using #8-32 x 3/16 flathead

screws (four to eight on each side). The right and left side brackets are identical.

Note – To allow adjustment of the brackets, do not tighten the screws completely

until the enclosure is mounted in the rack.

a. Use the alignment marks (Figure 2-2) stamped into the side brackets to position

the brackets and screws. The alignment marks show depth in inches.

Determine the depth you require and align the rear-most alignment mark on the

side bracket with the rear-most threaded holes on the enclosure. Make sure that

the alignment mark corresponding to the depth you want lines up with both the

top and bottom holes.


Figure 2-2 Side Bracket With Alignment Marks

b. On one side, insert the first two screws through the side bracket slots above and

below the alignment mark into the rear-most threaded holes in the enclosure.

For example, to mount the enclosure in a 28-inch deep rack, position the side

bracket so that the 28-inch alignment mark is aligned with the rear-most threaded

holes in the enclosure.

c. Insert up to six more screws through the side bracket slots into the other threaded

holes in the side of the enclosure.

d. Repeat Step b and Step c to attach the other side bracket to the enclosure.

6. Attach the rear brackets to the rear vertical posts of the rack using #‘10-32 x 5/8

screws (two per bracket).

7. Lift the enclosure and slide the side brackets into the rear brackets, which are

attached to the rear posts.

Adjust the depth of the side brackets so that the slots nearest the ends of the side

brackets align with the four PEM nuts in the rear brackets.

8. Attach each side bracket to a rear bracket using #8-32 x 1/4 screws (four per

bracket).

9. Ensure that the enclosure is level, and then, secure the mounting ears on the front of

the enclosure to the rack face using #10-32 x 5/8 screws (two per ear).

10. Tighten the screws on the side brackets.

11. If you removed modules from the enclosure, reinsert them.

12. If you attached the optional front support nylon brackets to the rack face, remove

those brackets.

Note – When you finish installing an enclosure, you may have unused screws left

in your rack kit; extra screws are provided in case any are misplaced.


Attaching the Ear Caps

The plastic ear caps are snap-on parts that require some care when attaching or

removing them. After the enclosure has been installed in the rack cabinet, attach the

ear caps, which are located in a plastic bag included in the controller and drive

enclosure packages.

1. Remove the ear caps from the plastic package.

2. As you attach each ear cap, hold it so that its indent is closest to the chassis.

Figure 2-3 Attaching Ear Caps

3. Apply gentle pressure to snap the caps onto the chassis’ ears.

Connecting Controller and Drive Enclosures

Use the supplied SAS cables to connect a controller enclosure to up to three drive

enclosures. Figure 2-4 and Figure 2-5 show the recommended fault-tolerant cabling

patterns. In an enclosure, the upper module is designated A and the lower module is

designated B.

When connecting multiple drive enclosures, use reverse cabling to ensure the

highest level of fault tolerance. For example, Figure 2-5 shows controller A

connected to expansion module 1A, and the chain of connections continuing down.

Controller B is connected to the lower module (B) of the last drive enclosure in the

chain, with connections moving in the opposite direction.

Fault-tolerant cabling is recommended because it enables the controllers to access

remaining drive enclosures if any one drive enclosure fails. However, the system

also supports non-fault-tolerant cabling using the supplied SAS cables.

Figure 2-6 shows non-fault-tolerant cabling between a controller and up to three

drive enclosures.

Note – For clarity, the schematic illustrations of the controllers shown in this

section show only relevant details such as expansion ports. For detailed illustrations

showing all components, see “Hardware Components and LEDs” on page 13.

Connecting AC Power

Use this procedure to connect AC power to the enclosures.

1. Verify that both power switches are off.

2. Using the AC power cords, for each enclosure, connect one power-and-cooling

module to one power source in the rack, and the other power-and cooling-module to

a separate power source in the rack.

3. Connect the primary power cords from the rack to separate external power sources.

Power on the system as described in the following section.


Testing the Enclosure Connections

Use this procedure to power on the newly installed system.

1. Press the power switches at the back of each drive enclosure to the On position.

This ensures that the disks in the enclosures have enough time to completely spin up

before being scanned by the RAID modules in the controller enclosure.

While enclosures power up, their LEDs blink. After the LEDs stop blinking, if no

LEDs on the front and back of the enclosure are amber, the power-on sequence is

complete and no faults have been detected.

For a description of LED behavior and status, see “Hardware Components and

LEDs” on page 13.

2. Press the power switches at the back of the controller enclosure to the On position.

Depending on the number and type of drives in the system, it can take several

minutes for the system to power up.

If the enclosure’s power-on sequence succeeds as described in Step 1, the system is

ready to use.

General Practice for Powering the System Off and On

The system rarely needs to be powered off. You remove power only when you plan

to physically move the system to another location.

Use this procedure when you need to power off the system.

1. Stop all I/O from hosts to the system.

2. Use SMU to shut down both controllers.

Wait until SMU indicates that processing is complete.

3. Press the power switches at the back of the controller enclosure to the Off position.

4. Press the power switches at the back of each drive enclosure to the Off position.


When powering on the system, make sure to power up the enclosures and associated

data host in the following order:

1. Drive enclosures first

2. Controller enclosure next

3. Data hosts last (if they are powered down for maintenance purposes)

Obtaining IP Values for Your Storage System

To obtain the IP values for your system:

1. Look in the DCHP server’s address for the two IP addresses assigned to an “HP

StorageWorks MSA2000 Family” storage device.

2. Use a network management utility to discover “HP StorageWorks MSA2000

Family” storage devices on the local LAN through SNMP.

3. Use a ping broadcast to try to identify the device through the host’s ARP table.

If you do not have a DHCP server, you will need to obtain the IP addresses from

your network administrator, and set them using the CLI during initial configuration

(see “Setting Management Port IP Addresses Using the CLI” on page 42).

Correcting Enclosure IDs

When installing a system with drive enclosures attached, the enclosure IDs might

not agree with the physical cabling order. This is because the controller might have

been previously attached to some of the same enclosures and it attempts to preserve

the previous enclosure IDs if possible. To correct this condition, see “Correcting

Enclosure IDs” on page 55.

CHAPTER 3

Connecting Hosts

This chapter describes how to connect data and management hosts to controller

enclosures. It contains the following sections:

n “Host System Requirements” on page 39

n “Connecting the Enclosure to Data Hosts” on page 40

n “Connecting Remote Management Hosts” on page 40

Host System Requirements

Data hosts connected to MSA2000 Family 2012sa Modular Smart Arrays must meet

the following requirements:

n To configure an HBA that is directly attached to controller enclosure host ports,

set the HBA parameters as specified in the MSA QuickSpecs. QuickSpecs can be

found from your HP MSA products page at http://www.hp.com/go/msa.

Select MSA SAN Arrays, and then select your product. The link for QuickSpecs

will be on the right.

n Depending on your system configuration, data host operating systems may

require that multipathing is supported.

If fault tolerance is required, then multipathing software may be required. Host-

based multipath software should be used in any configuration where two logical

paths between the host and nay storage volume may exist at the same time. This

would include most configurations where there are multiple connections to the

host or multiple connections between a switch and the storage.

To obtain the MSA2000 Family MPIO DSM, go to the HP MSA products page at

http://www.hp.com/go/msa. Select MSA SAN Arrays, select your product,

and go to Related products.

n To prevent Microsoft® Windows® data hosts from displaying the Found New

Hardware Wizard when the storage system is discovered, install the MSA2000

Family SCSI Enclosure Services driver. For more information, see “Installing the

MSA2000 Family SES Driver for Microsoft Windows Hosts” on page 40.


Installing the MSA2000 Family SES Driver for Microsoft Windows Hosts

Installing the MSA2000 Family SCSI Enclosure Services (SES) driver prevents

Microsoft Windows hosts from displaying the Found New Hardware Wizard when

the storage system is discovered.

1. Download MSA2000 Family SCSI Enclosure Services (SES) driver package

msa2000-ses-version.zip from the http://www.hp.com/go/msa. Select MSA

SAN Arrays, select your product, and go to Related products.

2. Extract the package contents to a temporary folder on the host.

3. In that folder, double-click Setup.exe to install the driver.

4. Click Finish.

The driver is installed.

5. Optionally, delete the extracted files and the SES driver package.

Connecting the Enclosure to Data Hosts

Cable connections vary depending on configuration. For a complete list of

supported configurations, go to the MSA2000 product site at

http://www.hp.com/go/msa for the latest MSA2000 Configuration Options

guide. This document is updated whenever newly supported configurations are

added.

Connecting Remote Management Hosts

The management host directly manages systems out-of-band over an Ethernet

network. This section describes how to connect the Ethernet cables to the

management host.

1. Connect an Ethernet cable to the Ethernet management port on each controller.

2. Connect the other end of each Ethernet cable to a network that your management

host can access (preferably on the same subnet).

41

CHAPTER 4

Configuring a System for the First Time

This chapter describes how to perform first-time configuration on the storage

system using HP StorageWorks MSA2000 Family Storage Management Utility

(SMU), which is the primary interface for configuring and managing the system. It

also describes how to perform basic storage configuration to verify that your system

is working.

This chapter includes the following topics:

n “Setting Management Port IP Addresses Using the CLI” on page 42

n “Configuring Your Web Browser for SMU” on page 46

n “Logging in to SMU from a Local Management Host” on page 46

n “Updating Firmware” on page 47

n “Setting the Date and Time” on page 47

n “Creating Virtual Disks” on page 48

n “Mapping a Volume to a Host” on page 50

n “Testing the Configuration” on page 50

n “Logging Out of SMU” on page 51

For information about additional configuration and management tasks, including

changing the manage user’s password, refer to SMU’s online help or the reference

guide.


Setting Management Port IP Addresses Using the CLI

Note – If you used DHCP to set the IP addresses, you do not have to set them using

the CLI as described in this section.

Ethernet Management ports on controller module A and controller module B are

configured with the following default values:

n Management Port IP Address: 10.0.0.2 (controller A), 10.0.0.3 (controller B)

n IP Subnet Mask: 255.255.255.0

n Gateway IP Address: 10.0.0.1

If the default IP addresses are not compatible with your network, you must set an IP

address for each management port using the command-line interface (CLI)

embedded in each controller module. The CLI enables you to access the system

using RS-232 communication and terminal emulation software.

Use the CLI commands described in the steps below to set the IP address for the

Ethernet management port on each controller module.

Once new IP addresses are set, you can change them as needed using SMU.

Note – Changing IP settings can cause management hosts to lose access to the

storage system.

1. From your network administrator obtain an IP address, subnet mask, and gateway

address for controller A and controller B.

2. Use the provided micro-DB9 serial cable to connect controller A to a serial port on

a host computer.

Chapter 4 Configuring a System for the First Time 43

Your package contents include a micro-DB9-to-DB9 serial cable. If necessary, use a

DB9-to-DB25 adapter (not included) for connecting the serial cable to a DB25

serial port on the host computer.

3. Start and configure a terminal emulator, such as HyperTerminal or VT-100, using

the display settings in Table 4-1 and the connection settings in Table 4-2.

4. In the terminal emulator, connect to controller A.

5. Press Enter to display the CLI prompt (#).

6. At the prompt, type the following command to set the values you obtained in Step 1

for each Ethernet management port, first for controller A and then for controller B:

where:

n address is the IP address of the controller

n netmask is the subnet mask

n gateway is the IP address of the subnet router

n a|b specifies the controller whose network parameters you are setting

For example:

7. Type the following command to verify the new IP addresses:

set network-parameters ip address netmask netmask gateway gateway controller a|b

# set network-parameters ip 192.168.0.10 netmask 255.255.255.0 gateway 192.168.0.1 controller a

# set network-parameters ip 192.168.0.11 netmask 255.255.255.0 gateway 192.168.0.1 controller b

show network-parameters


As shown in the following example, network parameters, including the IP address,

gateway address, and subnet mask are displayed for each controller.

8. In the host computer's command window, type the following command to verify

Ethernet connectivity, first for controller A and then for controller B:

If you cannot access your system three minutes after changing the IP address,

your network might require you to restart the management controller using the CLI.

When you restart a management controller, communication with it is temporarily

lost until it successfully restarts.

Type the following command to restart the management controller on both

controllers:

9. After you have verified Ethernet connectivity, disconnect the serial cable and exit

the emulator.

Network Parameters Controller A

Configuring Your Web Browser for SMU

Before using SMU to perform remaining steps, ensure that your web browser is

properly configured according to the following guidelines:

n Use one of the following browsers:

n Microsoft Internet Explorer 5.5 or later

n Mozilla Firefox 1.0.7 or later

n Because SMU uses popup windows to indicate the progress of user-requested

tasks, disable any browser features or tools that block popup windows.

n For optimal performance, set your browser to use stored (cached) web pages.

Note – Changing your browser cache setting might affect other sites you visit with

your browser.

n To optimize display, use a color monitor and set its color quality to the highest

setting.

n For Internet Explorer, to ensure you can navigate beyond SMU login page, set

the local-intranet security option to medium or medium-low.

Logging in to SMU from a Local Management Host

To log in to SMU from a local management host:

1. In your web browser’s address field, type the IP address of one of the controller

enclosure’s Ethernet management ports and press Enter.

The SMU Login page is displayed. If the Login page does not display, verify that

you have entered the correct IP address.

2. On the login page, type the default management user name manage and default

password !manage

3. Click Log In.

The Status Summary page is displayed.


Updating Firmware

After installing the hardware and powering up the enclosure for the first time, be

sure to verify that the controllers and drive enclosures have the latest firmware.

SMU enables you to view the software, hardware, and other version information for

each controller and the enclosures.

To view controller version information, select Monitor > Status > Advanced

Settings > Controller Versions. To view drive enclosure information, select Manage

> Update Software > Enclosure Firmware > Show Enclosures.

Selecting an Appropriate Time to Perform the Online Upgrade

To ensure the success of an line upgrade, selecting the appropriate time is essential.

Selecting a period of low I/O activity will ensure the upgrade completes as quickly

as possible, and will avoid disruptions to host and applications due to timeouts.

Attempting to upgrade a storage system that is in the middle of processing a large

I/O intensive batch job will likely cause hosts to lost connectivity with the storage

system. Consequently, finding an appropriate time for the upgrade is very important.

For software and firmware updates, go to http://www.hp.com/go/msa. Select

MSA SAN Arrays, select your product, and go to Support.

For detailed steps on updating the firmware, see the reference guide.

Setting the Date and Time

You can set the date and time manually or configure the system to use Network

Time Protocol (NTP) to obtain them from a network-attached server. When NTP is

enabled, and if an NTP server is available, the system time and date can be obtained

from the NTP server. This allows multiple storage devices, hosts, log files, and so

forth to be synchronized.

NTP server time is provided in Universal Time (UT), which provides several

options:

n If you want to synchronize the times and logs between storage devices installed

in multiple time zones, set all the storage devices to use UT.

n If you want to use the local time for the device, select the appropriate time zone.

n If a time server can provide local time rather than UT, configure the storage

devices to use that time server, with no further time adjustment.


If no NTP server is present, the date and time are maintained as if NTP had not been

enabled.

To manually set the system date and time:

1. Select Manage > General Config > Set Date/Time.

2. In the Set System Date panel, select the current month, day, and year.

3. In the Set System Time panel, type time values using a 24-hour clock (where hour 8

represents 8 a.m. and hour 20 represents 8 p.m.) and select the proper time zone.

4. Click Change Date/Time.

To obtain the date and time from an NTP server:

1. Select Manage > General Config > Set Date/Time.

2. In the Obtain Time With NTP panel, set Network Time Protocol to Enable and

optionally type the IP address of an NTP server.

If no IP server address is set, the system listens for time messages sent by an NTP

server in broadcast mode.

3. In the Set System Time panel, select the proper time zone.

4. Click Change Date/Time.

You might have to refresh the page to display updated values from the NTP server.

Creating Virtual Disks

Two or more disk drives can be logically combined to form a virtual disk. The

combined storage capacity can then be partitioned into volumes. SMU provides both

manual and automatic methods for creating virtual disks, as described in its online

help and in the reference guide.

As an example, the following steps use the manual method to create two virtual

disks with the following characteristics:

n RAID 5, in which parity is distributed across all disk drives in the virtual disk

n Five disk drives per virtual disk

n One spare disk drive dedicated to each virtual disk

n One volume per virtual disk, where the volume is not visible to data hosts


To create both virtual disks:

1. Select Manage > Virtual Disk Config > Create A Vdisk.

2. Select Manual Virtual Disk Creation.

3. Type a name for the virtual disk.

The name is case-sensitive and can include 17 characters. Allowed characters

include letters, numbers, hyphens, underscores, and spaces.

4. Select RAID 5 – Parity RAID, Parity Distributed.

5. Click Create New Virtual Disk.

6. Select five drives of the same size and type (all SAS or all SATA).

7. For the dedicated spare drive option, select Yes and click Continue.

You can add a maximum of four available drives to a redundant virtual disk (RAID

1, 3, 5, 6, 10, and 50) for use as spares. If a drive in the virtual disk fails, one of

these vdisk spares is automatically used to reconstruct the virtual disk. A spare drive

must have sufficient capacity to replace the smallest drive in the virtual disk. Vdisk

spares are also called dedicated spares.

The controller automatically uses the vdisk spare for reconstruction of the critical

virtual disk to which it belongs. The virtual disk remains in Critical status until the

parity or mirror data is completely written to the spare, at which time the virtual

disk returns to Fault Tolerant status. For RAID 50 virtual disks, if more than one

sub-vdisk becomes critical, reconstruction and use of vdisk spares occur in the order

sub-vdisks are numbered.

Although using a vdisk spare is the most secure way to provide spares for your

virtual disks, it is also expensive to keep a spare assigned to each virtual disk. An

alternative method is to enable dynamic spares or to assign one or more unused

drives as global spares.

8. Select a drive to be the spare and click Continue.

9. For the number of volumes, select 1.

Notice that by default the volume will not be presented to (accessible by) hosts.

10. Click Create Virtual Disk.

A page is displayed that shows the progress of initializing the virtual disk.

11. Click the link to create another virtual disk.

12. Repeat Step 2 to Step 10 to create a second virtual disk with a different name.


Mapping a Volume to a Host

To enable a data host to access a volume you created, you must map the volume to

the host. The port World Wide Name (WWN) of each host connected to the system

is automatically added to the system’s global host port list.

Before mapping a data host to a volume you must identify the data host’s port

WWN and a LUN that the host is not using.

To map a data host to a volume:

1. Select Manage > Volume Management > Volume Mapping > Map Hosts To Volume.

Notice that your first virtual disk and its volume are selected, and the volume’s host

mapping values are set to None.

2. In the Add or Modify a Mapping panel:

a. Select the host WWN value that you identified before beginning.

b. Type the LUN.

c. Leave the access type set as read-write.

d. Select all ports.

e. Click Map It.

The host has read-write access to the volume through any controller host port.

Testing the Configuration

To determine that your system is ready for use, test the configuration as follows:

1. In SMU, select Monitor > Vdisk Status and view the configuration information for

each virtual disk.

The virtual disk status is Critical during initialization but you can perform I/O to the

volume.

2. From the data host:

a. Create a file system on the volume.

b. Verify that you can access the mapped volume and the volume size shown on the

data host matches the size shown in SMU.

c. Verify that you can write data to the volume.


If the above tests succeed, your system is ready for use.

3. Optionally, unmount the volume and delete the vdisks created for test.

Logging Out of SMU

If you do not log out of SMU when you have finished using it, other manage users

cannot log in to the same controller module and your IP address stays logged in for

30 minutes (the default auto-logout timeout setting).

To log out of SMU:

1. Click Log Off at the bottom of the menu.

The Log Off page is displayed.

2. Click Log Off.

CHAPTER 5

Troubleshooting

Fault Isolation Methodology

The MSA2000 Family storage system provides many ways to isolate faults within

the system. This section presents the basic methodology used to locate faults and the

associated FRUs.

The basic fault isolation steps are:

n Gather fault information, including by using system LEDs

n Determine where in the system the fault is occurring

n Review event logs

n If required, isolate the fault to a data path component

Gather Fault Information

When a fault occurs, it is important to gather as much information as possible.

Doing so will help you determine the correct action needed to remedy the fault.

Begin by reviewing the reported fault. Is the fault related to an internal data path or

an external data path? Is the fault related to a hardware component such as a drive

module, controller module, or power-and-cooling module? By isolating the fault to

one of the components within the storage system, you will be able to determine the

necessary action more rapidly.

Determine Where the Fault Is Occurring

Once you have an understanding of the reported fault, review the enclosure LEDs.

The enclosure LEDs are designed to alert users of any system faults and might be

what alerted the user to a fault in the first place.


When a fault occurs, the Fault ID status LED on an enclosure’s right ear (see

Figure 1-1) illuminates. Check the LEDs on the back of the enclosure to narrow the

fault to a FRU, connection, or both. The LEDs also help you identify the location of

a FRU reporting a fault.

Use SMU to verify any faults found while viewing the LEDs. SMU is also a good

tool to use in determining where the fault is occurring if the LEDs cannot be viewed

due to the location of the system. SMU provides you with a visual representation of

the system and where the fault is occurring. It can also provide more detailed

information about FRUs, data, and faults.

Review the Event Logs

The event logs record all system events. It is very important to review the logs, not

only to identify the fault, but also to search for events that might have caused the

fault to occur. For example, a host could lose connectivity to a virtual disk if a user

changes channel settings without taking the storage resources assigned to it into

consideration. In addition, the type of fault can help you isolate the problem to

hardware or software.

Isolate the Fault

Occasionally it might become necessary to isolate a fault. This is particularly true

with data paths due to the number of components the data path consists of. For

example, if a host-side data error occurs, it could be caused by any of the

components in the data path: controller module, cable, or data host.

Chapter 5 Troubleshooting 55

If the Enclosure Does Not Initialize

It may take up to two minutes for the enclosures to initialize. If the enclosure does

not initialize:

n Perform a rescan.

n Power cycle the system.

n Make sure the power cord is properly connected and check the power source that

it is connected to.

n Check the event log for errors.

Correcting Enclosure IDs

When installing a system with drive enclosures attached, the enclosure IDs might

not agree with the physical cabling order. This is because the controller might have

been previously attached to some of the same enclosures and it attempts to preserve

the previous enclosure IDs if possible. To correct this condition, make sure that both

controllers are up and perform a rescan using SMU or the CLI. This will reorder the

enclosures, but can take up to two minutes for the enclosure IDs to be corrected.

To perform a rescan using the CLI, type the following command:

To rescan using SMU:

1. Select Manage > General Config > Enclosure Management > Reorder Enclosure

IDs.

2. In the Reorder Enclosure IDs panel, click Rescan.

Isolating a Host-Side Connection Fault

During normal operation, when a controller module host port is connected to a data

host, the port’s host link status LED and host link activity LED are green. If there is

I/O activity, the host activity LED blinks green. If data hosts are having trouble

accessing the storage system, and you cannot locate a specific fault or cannot access

the event logs, use the following procedure. This procedure requires scheduled

downtime.

Note – Do not perform more than one step at a time. Changing more than one

variable at a time can complicate the troubleshooting process.

1. Halt all I/O to the storage system.

2. Check the host activity LED.

If there is activity, halt all applications that access the storage system.

3. Reseat the SAS cable.

Is the host link status LED on?

n Yes – Monitor the status to ensure that there is no intermittent error present. If

the fault occurs again, clean the connections to ensure that a dirty connector is

not interfering with the data path.

n No – Proceed to the next step.

4. Move the SAS cable to a port with a known good link status.

This step isolates the problem to the external data path (host cable and host-side

devices) or to the controller module port.


n Yes – You now know that the host cable and host-side devices are functioning

properly. Return the cable to the original port. If the link status LED remains off,

you have isolated the fault to the controller module’s port. Replace the controller

module.


5. Replace the HBA with a known good HBA, or move the host side cable to a known

good HBA.



n Yes – You have isolated the fault to the HBA. Replace the HBA.

n No – It is likely that the controller module needs to be replaced.

6. Move the cable back to its original port.


n No – The controller module’s port has failed. Replace the controller module.

n Yes – Monitor the connection for a period of time. It may be an intermittent

problem, which can occur with damaged cables and HBAs.

Isolating a Controller Module Expansion Port Connection Fault

During normal operation, when a controller module’s expansion port is connected to

a drive enclosure, the expansion port status LED is green. If the connected port’s

expansion port LED is off, the link is down. Use the following procedure to isolate

the fault.

This procedure requires scheduled downtime.

Note – Do not perform more than one step at a time. Changing more than one

variable at a time can complicate the troubleshooting process.

1. Halt all I/O to the storage system.

2. Check the host activity LED.

If there is activity, halt all applications that access the storage system.

3. Reseat the expansion cable.

Is the expansion port status LED on?

n Yes – Monitor the status to ensure there is no intermittent error present. If the

fault occurs again, clean the connections to ensure that a dirty connector is not

interfering with the data path.

n No – Proceed to Step 4.


4. Move the expansion cable to a port on the RAID enclosure with a known good link

status.

This step isolates the problem to the expansion cable or to the controller module’s

expansion port.


n Yes – You now know that the expansion cable is good. Return cable to the

original port. If the expansion port status LED remains off, you have isolated

the fault to the controller module’s expansion port. Replace the controller

module.


5. Move the expansion cable back to the original port on the controller enclosure.

6. Move the expansion cable on the drive enclosure to a known good expansion port

on the drive enclosure.


n Yes – You have isolated the problem to the drive enclosure’s port. Replace the

expansion module.

n No – Proceed to Step 7.

7. Replace the cable with a known good cable, ensuring the cable is attached to the

original ports used by the previous cable.


n Yes – Replace the original cable. The fault has been isolated.

n No – It is likely that the controller module needs to be replaced


Resolving Voltage and Temperature Warnings

1. Check that all of the fans are working by making sure each power-and-cooling

module’s DC Voltage/Fan Fault/Service Required LED is off or by using SMU to

check the Status Summary page (select Monitor > Status > Status Summary).

2. Make sure that all modules are fully seated in their slots and that their latches are

locked.

3. Make sure that no slots are left open for more than two minutes.

If you need to replace a module, leave the old module in place until you have the

replacement or use a blank module to fill the slot. Leaving a slot open negatively

affects the airflow and can cause the enclosure to overheat.

4. Try replacing each power-and-cooling module one at a time.

5. Replace the controller modules, one at a time.

Sensor Locations

The storage system monitors conditions at different points within each enclosure to

alert you to problems. Power, cooling fan, temperature, and voltage sensors are

located at key points in the enclosure. In each controller module and expansion

module, the enclosure management processor (EMP) monitors the status of these

sensors to perform SCSI enclosure services (SES) functions. Various SMU pages

display the sensor information, for example Monitor > Status > Module Status.

The following sections describe each element and its sensors.


Power Supply Sensors

Each enclosure has two fully redundant power-and-cooling modules with load-

sharing capabilities. The power supply sensors described in the following table

monitor the voltage, temperature, and fans in each power-and-cooling module. If the

power supply sensors report a voltage that is under or over the threshold, check the

input voltage.

Cooling Fan Sensors

Each power-and-cooling module includes two fans. The normal range for fan speed

is 4000 to 6000 RPM. When a fan’s speed drops below 4000 RPM, the EMP

considers it a failure and posts an alarm in the storage system’s event log. The

following table lists the description, location, and alarm condition for each fan. If

the fan speed remains under the 4000 RPM threshold, the internal enclosure

temperature may continue to rise. Replace the power-and-cooling module reporting

the fault.

During a shutdown, the cooling fans do not shut off. This allows the enclosure to

continue cooling.

Power supply 2 Power-and-cooling module 1 Voltage, temperature, or fan fault

Table 5-2 Cooling Fan Sensor Descriptions

Description Location Event/Fault ID LED Condition

Fan 0 Power-and-cooling module 0 < 4000 RPM





Temperature Sensors

Extreme high and low temperatures can cause significant damage if they go

unnoticed. Each controller module has six temperature sensors. Of these, if the CPU

or FPGA temperature reaches a shutdown value, the controller module is

automatically shut down. Each power-and-cooling module has one temperature

sensor.

When a temperature fault is reported, it must be remedied as quickly as possible to

avoid system damage. This can be done by warming or cooling the installation

location.

When a power supply sensor goes out of range, the Fault/ID LED illuminates amber

and an event is logged to the event log.

APPENDIX A

Environmental Requirements and Specifications

Safety Requirements

Install the system in accordance with the local safety codes and regulations at the

facility site. Follow all cautions and instructions marked on the equipment.

Site Requirements and GuidelinesThe following sections provide requirements and guidelines that you must address

when preparing your site for the installation.

When selecting an installation site for the system, choose a location not subject to

excessive heat, direct sunlight, dust, or chemical exposure. These conditions greatly

reduce the system’s longevity and might void your warranty.

Site Wiring and AC Power Requirements

The following are required for all installations:

n All AC mains and supply conductors to power distribution boxes for the rack-

mounted system must be enclosed in a metal conduit or raceway when specified

by local, national, or other applicable government codes and regulations.

n Ensure that the voltage and frequency of your power source match the voltage

and frequency inscribed on the equipment’s electrical rating label.

n To ensure redundancy, provide two separate power sources for the enclosures.

These power sources must be independent of each other, and each must be

controlled by a separate circuit breaker at the power distribution point.

n The system requires voltages within minimum fluctuation. The customer-

supplied facilities’ voltage must maintain a voltage with not more than

±5 percent fluctuation. The customer facilities must also provide suitable surge

protection.


n Site wiring must include an earth ground connection to the AC power source.

The supply conductors and power distribution boxes (or equivalent metal

enclosure) must be grounded at both ends.

n Power circuits and associated circuit breakers must provide sufficient power and

overload protection. To prevent possible damage to the AC power distribution

boxes and other components in the rack, use an external, independent power

source that is isolated from large switching loads (such as air conditioning

motors, elevator motors, and factory loads).

Weight and Placement Guidelines

Refer to “Physical Requirements” on page 74 for detailed size and weight

specifications.

n The weight of an enclosure depends on the number and type of modules installed,

as shown in Table A-2.

n Ideally, use two people to lift an enclosure. However, one person can safely lift

an enclosure if its weight is reduced by removing the power and cooling modules

and drive modules.

n Do not place enclosures in a vertical position. Always install and operate the

enclosures in a horizontal orientation.

n When installing enclosures in a rack, make sure that any surfaces over which you

might move the rack can support the weight. To prevent accidents when moving

equipment, especially on sloped loading docks and up ramps to raised floors,

ensure you have a sufficient number of helpers. Remove obstacles such as cables

and other objects from the floor.

n To prevent the rack from tipping and to minimize personnel injury in the event of

a seismic occurrence, securely anchor the rack to a wall or other rigid structure

that is attached to both the floor and to the ceiling of the room.

Appendix A Environmental Requirements and Specifications 73

Electrical Guidelinesn These enclosures work with single-phase power systems having an earth ground

connection. To reduce the risk of electric shock, do not plug an enclosure into

any other type of power system. Contact your facilities manager or a qualified

electrician if you are not sure what type of power is supplied to your building.

n Enclosures are shipped with a grounding-type (three-wire) power cord. To reduce

the risk of electric shock, always plug the cord into a grounded power outlet.

n Do not use household extension cords with the enclosures. Not all power cords

have the same current ratings. Household extension cords do not have overload

protection and are not meant for use with computer systems.

Ventilation Requirements

Refer to “Environmental Requirements” on page 75 for detailed environmental

requirements.

n Do not block or cover ventilation openings at the front and rear of an enclosure.

Never place an enclosure near a radiator or heating vent. Failure to follow these

guidelines can cause overheating and affect the reliability and warranty of your

enclosure.

n Leave a minimum of 6 inches (15 cm) at the front and back of each enclosure to

ensure adequate airflow for cooling. No cooling clearance is required on the

sides, top, or bottom of enclosures.

n Leave enough space in front and in back of an enclosure to allow access to

enclosure components for servicing. Removing a component requires a clearance

of at least 15 inches (37 cm) in front of and behind the enclosure.

Cabling Requirementsn Keep power and interface cables clear of foot traffic. Route cables in locations

that protect the cables from damage.

n Route interface cables away from motors and other sources of magnetic or radio

frequency interference.

n Stay within the cable length limitations.


Management Host Requirements

A local management host with at least one serial port connection is recommended

for the initial installation and configuration of a controller enclosure. After you

configure one or both of the controller modules with an Internet Protocol (IP)

address, you then use a remote management host on an Ethernet network to

configure, manage, and monitor.

Note – Connections to this device must be made with shielded cables with metallic

RFI/EMI connector hoods in order to maintain compliance with FCC Rules and

Regulations.

Physical Requirements

The floor space at the installation site must be strong enough to support the

combined weight of the rack, controller enclosures, expansion enclosures, and any

additional equipment. The site also requires sufficient space for installation,

operation, and servicing the enclosures, and also requires sufficient ventilation to

allow a free flow of air to all enclosures.

Table A-1 and Table A-2 list enclosure dimensions and weights. Weights are based

on an enclosure having 12 drive modules, two controller or expansion modules, and

two power-and-cooling modules installed.

Electrical Requirements

Site Wiring and Power Requirements

Each enclosure has two power and cooling modules for redundancy. If full

redundancy is required, use a separate power source for each module. The AC

power supply unit in each power and cooling module is auto-ranging and is

automatically configured to an input voltage range from 88–264 VAC with an input

frequency of 47–63 Hz. The power and cooling modules meet standard voltage

requirements for both U.S. and international operation. The power and cooling

modules use standard industrial wiring with line-to-neutral or line-to-line power

connections.

Power Cord Requirements

Each enclosure is shipped with two AC power cords that are appropriate for use in

a typical outlet in the destination country. Each power cord connects one of the

power and cooling modules to an independent, external power source. To ensure

power redundancy, connect the two power cords to two separate circuits; for

example, to one commercial circuit and one uninterruptible power source (UPS).

Regulatory Compliance and Safety

Regulatory Compliance

Federal Communications Commission Notice

Part 15 of the Federal Communications Commission (FCC) Rules and Regulations

has established Radio Frequency (RF) emission limits to provide an interference-

free radio frequency spectrum. Many electronic devices, including computers,

generate RF energy incidental to their intended function and are, therefore, covered

by these rules. These rules place computers and related peripheral devices into two

classes, A and B, depending upon their intended installation. Class A devices are

those that may reasonably be expected to be installed in a business or commercial

environment. Class B devices are those that may reasonably be expected to be

installed in a residential environment (i.e., personal computers). The FCC requires

devices in both classes to bear a label indicating the interference potential of the

device as well as additional operating instructions for the user.

The rating label on the device shows which class (A or B) the equipment falls into.

Class B devices have an FCC logo or FCC ID on the label. Class A devices do not

have an FCC logo or FCC ID on the label. Once the class of the device is

n Do not attempt to recharge the battery.

n Do not expose to temperatures higher than 60°C.

n Do not disassemble, crush, puncture, short external contacts, or dispose of in fire

or water.

n Replace only with the HP spare part designated for this product.

For more information about battery replacement or proper disposal, contact an HP

authorized reseller or service provider.

Taiwan Battery Recycling Notice

Batteries, battery packs, and accumulators should not be disposed of together with the

general household waste. To forward them to recycling or proper disposal, please use the

public collection system or return them to HP, an authorized HP Partner, or their agents.

The Taiwan EPA requires dry battery manufacturing or importing firms

in accordance with Article 15 of the Waste Disposal Act to indicate the recovery marks on the batteries used in sales, giveaway or promotion.

Contact a qualified Taiwanese recycler for proper battery disposal.


Power Cords

The power cord set must meet the requirements for use in the country where the

product was purchased. If the product is to be used in another country, purchase a

power cord that is approved for use in that country.

The power cord must be rated for the product and for the voltage and current

marked on the product electrical ratings label. The voltage and current rating of the

cord should be greater than the voltage and current rating marked on the product. In

addition, the diameter of the wire must be a minimum of 1.00 mm2 or 18 AWG, and

the length of the cord must be between 1.8 m (6 ft) and 3.6 m (12 ft). If you have

questions about the type of power cord to use, contact an HP authorized service

provider.

Japanese Power Cord Notice

Electrostatic Discharge

To prevent damage to the system, be aware of the precautions you need to follow

when setting up the system or handling parts. A discharge of static electricity from

a finger or other conductor may damage system boards or other static-sensitive

devices. This type of damage may reduce the life expectancy of the device.

Preventing Electrostatic Damage

To prevent electrostatic damage, observe the following precautions:

n Avoid hand contact by transporting and storing products in static-safe containers.

n Keep electrostatic-sensitive parts in their containers until they arrive at static-free

workstations.


n Place parts on a grounded surface before removing them from their containers.

n Avoid touching pins, leads, or circuitry.

n Always be properly grounded when touching a static-sensitive component or

assembly (see “Grounding Methods” on page 86).

Grounding Methods

There are several methods for grounding. Use one or more of the following methods

when handling or installing electrostatic-sensitive parts:

n Use a wrist strap connected by a ground cord to a grounded workstation or

computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm

(±10 percent) resistance in the ground cords. To provide proper ground, wear the

strap snug against the skin.

n Use heel straps, toe straps, or boot straps at standing workstations. Wear the

straps on both feet when standing on conductive floors or dissipating floor mats.

n Use conductive field service tools.

n Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an

HP authorized reseller install the part.

Note – For more information on static electricity, or assistance with product

installation, contact your HP authorized reseller.
