About EMC Navisphere server software

The EMC server-based software listed below is available on the serversupport CD that shipped with your storage system.

For information on the server software supported with yourCLARiiON® storage system and the minimum FLARE® versionrequired, refer to Software for your storage system, page 6 .

Navisphere Storage System Initialization Utility

Navisphere Host Agent

Navisphere Server Utility

Admsnap Utility

Navisphere Command Line Interface (CLI)

About the Navisphere Storage System Initialization Utility

For Fibre Channel storage systems, use the Navisphere® Initializationutility to discover storage systems and set network parameters (IPaddress, subnet mask, and default gateway). In addition, for iSCSIstorage systems with iSCSI data ports attached to Windows servers, usethe utility to set network parameters for these ports.

For CX series storage systems, an authorized service provider must install andrun the initialization utility.

You can run the initialization utility from the server support CD or youcan install it on a server or other host such as a Navisphere off-arraymanagement station. The only requirement is that the host be connectedto the same network subnet as the storage-system management ports.

About the Navisphere Host Agent

The host agent registers the server’s host bus adapter (HBA) with theattached storage system when the host agent service starts. This actionsends the initiator records for each HBA to the storage system. Initiatorrecords are used to control access to storage-system data.

The agent can then retrieve information from the storage systemautomatically at startup or when requested by Manager or CLI.

EMC CLARiiON Server Support Products for HP-UX Servers Installation Guide 3

The host agent can also:

Send operating system drive mapping information to the attachedCLARiiON® storage systems.

Monitor storage-system events and notify personnel by email, page,or modem when any designated event occurs.

Retrieve LUN world wide name (WWN) and capacity informationfrom Symmetrix® storage systems.

About the Navisphere Server Utility

The server utility allows you to perform the following functions:

Update server information to the storage system — Lets you sendthe server name and IP address to the storage system and, if neededlater on, allows you to update or view this data.

Verify server high availability (HA) — Lets you determine if theserver is configured for high availability (HA) by verifying thatthe server has at least one connection path to each storage-systemSP, and that PowerPath® or some other failover software, such asVMware native, DMP, PV Links, or HP native failover for 11iV3is running. The utility does not detect any other native failoversoftware, such as Sun StorEdge Traffic Manager or Linux nativemultipath (MPIO).

This feature is not available on iSCSI servers.

Use the snapshot feature — On storage systems with NavisphereExpress, you can start and stop a snapshot on the source server(server assigned to the source virtual disk or source LUN), or youcan allow or remove access to the snapshot by the secondary server(server assigned to the snapshot).

You can run the Navisphere Server Utility from the CD or you caninstall it on the servers that are connected to the storage system. Westrongly recommend that you install the utility on each server that isconnected to the storage system.


On AX4–5 series storage systems with Navisphere Manager, you cannot usethe server utility to manage snapshots. Instead, you must install and use theadmsnap utility.

About the Admsnap Utility

The Admsnap Utility is an executable program that you can runinteractively or with a script to manage SnapView® clones andsnapshots. The Admsnap Utility resides on the servers connected tothe storage system with the SnapView driver installed.

Use admsnap commands to:

Scan for new storage devices

Make storage devices inaccessible to the server operating system

Flush cache data to disk

List current snapshot devices

Map and unmap to a SnapView session

Start and stop a SnapView session

About the Navisphere CLI

The CLI complements, or is an alternative to Manager. It provides acommand line interface for storage-system management, includingstorage provisioning, status and configuration information retrieval,and control. You can use the CLI to automate management functionsthrough shell scripts and batch files. For more information, refer to theEMC Navisphere Command Line Interface (CLI) Reference Guide.

Installing and removing the Navisphere Storage System InitializationUtility

EMC recommends that you install the utility on the server; however,you can run the Navisphere Storage System Initialization Utility fromthe server support CD.

Installation prerequisites

To initialize a storage system using the Navisphere Storage SystemInitialization Utility, the server must meet the following requirements:

Run a supported version of the operating system.

Be connected to the same subnet as the 10/100 management ports ofthe storage system that you want to initialize. This server may alsobe a server with Fibre Channel connections to the storage system.

If you have an earlier version of the storage system initialization utilityinstalled, you must uninstall it before installing an updated version.

Installing the Navisphere Storage System Initialization Utility on an HP-UX server

EMC recommends that you install the most recent version of theNavisphere Storage System Initialization Utility software that isappropriate for your configuration. You can download the most recentversion from the software download page on the Powerlink website.You can also install the software from the server support CD; however,the CD may not contain the most recent version for your configuration.

1. Log in as superuser (root) on the HP-UX server that is on the samesubnet as the storage system.

2. If an earlier version of the initialization utility is installed on theserver, remove it before continuing.

To verify if the initialization utility is installed, enter the /usr/sbin/swlistcommand to get a list of the currently installed software.

3. To download the software for CX4 series, CX3 series, CX series, orAX4–5 series storage systems, do the following:


a. From the Navigator drop-down menu at the top right of thePowerlink website, select Software Downloads and Patches.

b. Select the appropriate Navisphere Storage System InitializationUtility version and download the zip file.

c. At the command line prompt, navigate to the directory whereyou saved the zip file and unzip the file.

d. Install the INITTOOL.dep file on the HP-UX server.

4. To install the software from the server support CD, do the following:

a. Insert the server support CD, which shipped with the storagesystem or the upgrade kit (for upgrading AX4–5 series systemsto Navisphere Manager).

b. At the command prompt (#) in an hpterm window, enter thefollowing command to create a CD directory:

mkdir /cdrom

c. Identify the device file by executing the following command:

ioscan -funC disk

This command lists all recognized drives and their associateddevice files. The filename will be similar to /dev/dsk/c1t2d0.

d. Mount the CD drive:

mount /dev/dsk/device_filename /cdrom

where device_filename is the device filename from step c. Forexample, mount /dev/dsk/c1t2d0 /cdrom.

e. Execute the following command to install the source depot:

/usr/sbin/swinstall -s /cdrom/hpux/INITTOOL.dep -x \mount_all_filesystems=false INITTOOL

f. At the command prompt (#), unmount a CD.

umount /cdrom



g. Remove the CD from the server’s CD drive.

Removing the Navisphere Storage System Initialization Utility on an HP-UX server

1. At the HP-UX server, log in as superuser (root).

2. Execute the following command to remove the initialization utility:

/usr/sbin/swremove -x mount_all_filesystems=false INITTOOL

The removal process begins. The removal process is complete whenthere is no error and the following message is displayed:

END swremove SESSION


Running the Navisphere Storage System Initialization Utility

You can start the storage system initialization utility from theserver on which it is installed or from the server support CD. Thestorage system initialization utility has three methods for executingcommands — a user interface (UI) version, a command line interfacethat can be scripted, or a text-based utility that cannot be scripted.Before continuing, make sure that the storage system is powered upcompletely.

For storage-system initialization, connect the server from which you arerunning the utility and the storage system to the same network subnet. Onceyou have assigned an IP address to the storage system, the server and storagesystem can be on different subnets.

Starting the initialization utility on an HP-UX server

To start the text-based version of the utility, enter:

/opt/Navisphere/bin/naviinittool

To start the command line version of the utility, enter:

/opt/Navisphere/bin/naviinittool and any of the command lineswitches in Using the command line initialization utility, page 13.

Starting the initialization utility on an HP-UX server from the CD

To start the text-based or command line version of the initializationutility from the CD, do the following:

1. In the server’s drive, insert the server support CD, which shippedwith the storage system or the upgrade kit (for AX4-5 series or AXseries systems upgrading to Navisphere Manager).

2. At the command prompt (#) in an hpterm window, enter thefollowing command to create a CD directory:

mkdir /cdrom

3. Identify the device file by executing the following command:


ioscan -funC disk

This command lists all recognized drives and their associateddevice files. The filename will be similar to /dev/dsk/c1t2d0

4. Mount the CD drive:


where device_filename is the device filename from step c. Forexample, mount /dev/dsk/c1t2d0 /cdrom

5. Depending on which version of the initialization utility you want tostart and run from the CD, enter the appropriate command:

Text-based version — /cdrom/hpux/naviinittool

Command line version — /cdrom/hpux/naviinittool and any ofthe command line switches in Using the command line initializationutility, page 13.

Using the text-based initialization utility

After you start the utility, it automatically scans the subnet forsupported storage systems. When this storage-system discoveryoperation is complete, the utility lists, by hardware serial number, alluninitialized and initialized storage systems it found. The hardwareserial number for CX4 series storage systems is on a hanging tag at therear of the storage system.The hardware serial number for CX3 andCX series storage systems is on a blue label located on the SPE chassisbehind the front bezel.The hardware serial number for AX4-5 and AXseries storage systems is on a blue label on the rear of the chassis.

If the storage system you are installing was not discovered, verify thecable connections between the storage system and the host runningthe utility.

Use the information in the “Storage-System Management Ports”worksheet from the storage-system configuration planning guide,planning worksheets document, or the administration worksheet,and follow the instructions on the screen to change the storagesystem’s name, to set the network parameters for the storage-system


management ports, and to set the storage system’s management useraccount settings.

For a CX4 or CX3 series storage systemIf you entered an SP IP address for the first time or changed an SP IPaddress, the utility reboots the storage system, and the SP fault light onthe back of each SP starts blinking. The reboot takes several minutesto complete. When it is completed, the SP fault light (LEDs) on eachSP stops blinking and remains off.

For an AX4-5 series storage systemIf you entered an SP IP address for the first time or changed an SPIP address, the utility reboots the storage system, and green activitylights flash. The reboot takes 5 to 6 minutes to complete. When it hascompleted, the power button on each SP remains solid/steady green.

Using the command line initialization utility

After you start the command line version of the initialization utility,use any of the switches below with the naviinittool .

Determining whether to install the host agent or server utility

Depending on your application needs, you can install the host agent,server utility, or both on an attached server.

If you want to install both applications, you must install version 6.22.20or later of the server utility either before or after you install the hostagent. The registration feature of the server utility will be disabledand the host agent will be used to register the server’s NICs or iSCSIHBAs to the storage system.

Prior to version 6.22.20 of the server utility, you could not install the host agentand server utility on the same server. However, you could install them ondifferent servers that are connected to the same storage system.

If you do not want to install both applications, but want to use someof the features available in the server utility, you can run the serverutility from the server support CD.

The host agent is not supported with AX4-5 series storage systems withNavisphere Express; you can only use the server utility.

Table 3 describes the differences between the host agent and the serverutility on a server attached to a storage system.

Depending on the version of the server utility, some of the features listed inTable 3 may not be available.

Table 3 Differences between the host agent and the server utility

Function Host agent Server utility

Pushes LUN mappingand OS information to thestorage system.

Yes – LUN mapping information isdisplayed in the Manager UI next tothe LUN icon or with the CLI usingthe -lunmapinfo command.

AX4–5 series storage systemsYes – LUN mapping information is displayed in theManager UI next to the LUN icon, or with the CLI usingthe -lunmapinfo command. In Navisphere Express thisinformation is displayed in the Manage Virtual Disks page.Note: The text Manually Registered appears next to thehostname icon in the Manager UI indicating that the host agent wasnot used to register this server.


Function Host agent Server utility

CX4 series, CX3 series, and CX series storage systemsNo – LUN mapping information is not sent to the storage system. Onlythe server’s name, ID, and IP address are sent to the storage system.Note: The text Manually Registered appears next to thehostname icon in the Manager UI indicating that the host agent wasnot used to register this server.

Runs automatically tosend information to thestorage system.

Yes – No user interaction isrequired.

AX4–5 series storage systemsNo – You must manually update the information bystarting the utility or you can create a script to run the utility. Sinceyou run the server utility on demand, you have more control as tohow often or when the utility is executed.CX4 series, CX3 series, and CX series storage systemsNo – You must manually update the information by starting the utilityor you can create a script to run the utility. Since you run the serverutility on demand, you have more control as to how often or when theutility is executed.

No – You can run the server utility’sHA validation feature from the CDwithout having to install the serverutility.

AX4–5 series storage systemsCurrently not supported.CX4 series, CX3 series, and CX series storage systemsYes – The HA validation feature verifies that failover software isinstalled on the server and that working paths exist between theserver and each SP in the storage system.

Requires networkconnectivity to the storagesystem.

Yes – Network connectivity allowsLUN mapping information to beavailable to the storage system.

AX4–5 series storage systemsNo – LUN mapping information is sent through adata path to the storage system.CX4 series, CX3 series, and CX series storage systemsNo – LUN mapping information is not sent to the storage system.Note that if you are using the server utility to upload a high availabilityreport to the storage system, you must have network connectivity.

Requires installation. Yes – You must install the hostagent on the server.

AX4–5 series storage systemsNo – You can run the server utility from the CD.However, we recommend that you install it on the server.CX4 series, CX3 series, and CX series storage systemsNo – You can run the server utility from the CD. However, werecommend that you install it on the server.

Note: If you install the host agent and then version 6.22.20 or later of the server utility, the server utility’s registration service feature willnot be installed. Prior to version 6.22.20 of the server utility, you could not install the host agent and server utility on the same server.


Requirements for the host agent, server utility, and CLI

To run the host agent, CLI, or server utility, your server must meetthe following requirements:

Run a supported version of the HP-UX operating system.

For Fibre Channel connections, have the EMC CLARiiONsupported HBA hardware and driver installed.

Be connected to at least one SP (two SPs for high-availability) ineach storage system either directly or through a switch or hub. EachSP must have an IP connection.

For the host agent and CLI only - Be on a TCP/IP network connectedto at least one SP (two SPs for high-availability) in the storagesystem. The TCP/IP network connection allows the server to sendLUN mapping information to the storage system and it allowsNavisphere Manager or CLI to communicate with the storagesystem over the network.

Have a configured TCP/IP network connection to any remote hoststhat you will use to manage the server’s storage systems, including:

any server whose browser you will use to access Manager 6.X.

any Windows Server 2008, 2003, or Windows 2000 serverrunning Storage Management Server software.

any AIX, HP-UX, Linux, VMware ESX Server, NetWare, Solaris,Windows Server 2003, or Windows 2000 server running the CLI.

If you want to use the CLI on the server to manage storage systems ona remote server, the server must be on a TCP/IP network connectedto both the remote server and each SP in the remote server’s storagesystem. The remote server can be running AIX, HP-UX, Linux, Solaris,or the Windows operating system.

For information about the specific revisions of the server operating systemand the storage-system FLARE and Access Logix software that are requiredfor your version of the host agent, see the release notes for the host agenton the EMC Powerlink website. To access this website, see Finding currentinformation, page 7 .


Installing or removing the Navisphere Host Agent and CLI

You can install both the host agent and CLI, or you can install themseparately. If you will install both, install the host agent first.

To modify an existing host agent configuration refer to the next section.

If you want to install the host agent and use some of the features in the serverutility, see Determining whether to install the host agent or server utility , page 16.

Installing the host agent and/or CLI on an HP-UX server

EMC recommends that you install the most recent version of theNavisphere Host Agent/ CLI software that is appropriate for yourconfiguration. You can download the most recent version from thesoftware download page on the Powerlink website. You can also installthe software from the server support CD; however, the CD may notcontain the most recent version for your configuration.


2. If an earlier version of the host agent or CLI is installed on theserver, remove it before continuing.

To verify if the host agent or CLI is installed, enter the /usr/sbin/swlistcommand to get a list of the currently installed software.



b. Select the appropriate Navisphere Host Agent/CLI version anddownload the zip file.


d. Install the NAVIAGNT.dep file on the HP-UX server.

4. To install the software from the server support CD (any storagesystem), do the following:



a. In the server’s drive, insert the server support CD that shippedwith your storage system or the upgrade kit (for upgradingAX4–5 series systems to Navisphere Manager).


mkdir /cdrom


ioscan -funC disk





e. Execute the following command to install the host agent,Navisphere CLI, or both:

/usr/sbin/swinstall -s /cdrom/hpux/NAVIAGNT.dep -x \mount_all_filesystems=false [NAVICLI] [NAVIAGENT][NAVICLI NAVIAGENT]

For AX4–5 storage systems with Navisphere Express, you can onlyinstall the Navisphere CLI; the host agent is not supported.

f. At the command prompt (#), unmount the CD.

umount /cdrom

g. Remove the CD from the server’s CD drive.

h. Use the swlist command to verify that the appropriate softwarewas installed.


5. If you have a multihomed host (multiple NIC cards installed onthe host), create an agentID.txt file to ensure that the agent findsthe correct NIC card.

A multihomed host machine has multiple IP addresses connected tonetworks; it is physically connected to multiple data links that can be on thesame or different networks. When you install Navisphere Host Agent on amultihomed host, the host agent, by default, binds to the first NIC in thehost. If your host is multihomed, for the host agent to successfully registerwith the desired CLARiiON storage system, you need to configure the hostagent to bind to a specific NIC. You do this by setting up an agentID.txt file.

a. Using a text editor that does not add special formatting, createor edit a file named agentID.txt (case sensitive) in either / (root)or in a directory of your choice.

b. Add the following two separate lines to the agentID.txt file,with no special formatting:

First line: Fully qualified hostname of the host

Second line: IP address of the HBA/NIC port that you

want Navisphere agent to use

For example, if your host is named host28 on the domainmydomain.com and your host contains two HBAs/NICs,HBA1/NIC1 with IP address 192.111.222.2 and HBA2/NIC2with IP address 192.111.222.3, and you want the host agent touse NIC 2, you would configure agentID.txt as follows:

host28.mydomain.com192.111.222.3

The agentID.txt file should contain only these two lines, without anyformatting. The first line should contain the hostname and the secondline should contain the IP address of the HBA/NIC port as describedabove. Both lines should end with a carriage return. As a result, thecursor will be on a third line but this line should not contain any text.

c. Save the agentID.txt file.


d. If you created the agentID.txt file in a directory other thanroot, for host agent to restart after a system reboot using thecorrect path to the agentID.txt file, set the environment variableEV_AGENTID_DIRECTORY to point to the directory whereyou created agentID.txt.

e. If a HostIdFile.txt file is located in the /etc/log/HostIdFile.txtdirectory shown for your operating system, delete or rename it.

f. Stop and then restart the host agent.

g. Once the host agent has restarted, verify that the host agent isusing the IP address that is entered in the agentID.txt file. Todo this, view the new HostIdFile.txt file. You should see the IPaddress that is entered in the agentID.txt file.

Modifying user login scripts

Use a text editor to modify login scripts as described below:

1. Use a text editor, such as vi, to make the following additions to thespecified paths in $HOME/.profile or $HOME/.cshrc:

add the text /opt/Navisphere/bin to PATH

add the text /opt/Navisphere/man to MANPATH

add the text /opt/Navisphere/lib to LD_LIBRARY_PATH

2. Run the $HOME/.profile or $HOME/.cshrc file and export eachpath you modified.

3. View the paths using the echo command as follows:

# echo $PATH

# echo $MANPATH

# echo $LD_LIBRARY_PATH

What next?

If you are setting up a new server, go to Running the Navisphere HostAgent , page 27. If you are just upgrading the host agent or CLI on anexisting system, you have finished the upgrade.

Removing the host agent or CLI on an HP-UX server



2. At the command prompt (#) in an hpterm window, execute one ofthe following commands:

To remove the host agent enter:

/usr/sbin/swremove -x mount_all_filesystems=falseNAVIAGENT

To remove the CLI enter:

/usr/sbin/swremove -x mount_all_filesystems=false NAVICLI

The removal process begins. The removal process is completewhen there is no error and the following message is displayed:END swremove SESSION


Configuring the Navisphere Host Agent

Before you can use the Navisphere CLI navicli register command toconfigure your storage system, you must make sure the host agentconfiguration file includes a privileged user, as described in Addingprivileged users, page 24.

The pathname of the host agent configuration file is /etc/Navisphere/agent.con-fig.

If you are configuring a legacy storage system, refer to revision A08 ofthis guide.

A legacy system is an FC series storage system that is not running storagemanagement server software.

Adding privileged users

If you will use Navisphere CLI to configure any storage system, thehost agent configuration file must include an entry that defines theperson who will issue the CLI commands as a privileged user.

To define a privileged user, add a local or remote privileged user byadding the appropriate entry below.

For a local user:

user name

For a remote user:

user name@hostname

where name is the person’s account name and hostname is the name ofthe remote server the person will be using.

The default host agent configuration file includes a user root entry.

Saving the host agent configuration file

1. Save the host agent configuration file.


2. If you have finished adding information to the host agentconfiguration file, stop and restart the host agent by entering thefollowing commands:

#/sbin/init.d/agent stop#/sbin/init.d/agent start


Using the Event Monitor configuration file

The Navisphere Host Agent can monitor storage-system events andtake such action as sending email or paging you if specified eventsoccur. The Event Monitor that ships with Navisphere Managerprovides an interactive way to define these events and actions. If youdo not have Event Monitor, you can still define such events and actionsby editing the Event Monitor configuration file.

/etc/Navisphere/Navimon.cfg

The file is self-documenting; that is, text in it describes how to defineevents and the actions you want taken if the events occur. You cantest the file after editing it using the Navisphere CLI commandresponsetest, as explained in the Navisphere Command Line InterfaceReference.


Running the Navisphere Host Agent

This section describes how to test the host agent connections and howto start and stop the host agent.

Starting and stopping the Navisphere Host Agent

The host agent starts automatically when you bring the serverup to init level 2. When you first start the host agent, look at thesystem log for the server’s operating system to make sure the agentstarted and no device errors occurred. The system log is located in/var/adm/syslog/syslog.log.

When a storage system experiences heavy input/output traffic (that is,applications are using the storage system), information may not be reportedto the host agent in a timely manner, resulting in the host agent taking severalminutes to execute a storage-system management task. This behavior is mostevident when one host agent is managing multiple storage systems. Also, if theSP event log is large and the host agent configuration file is set up to read allevents, it may take a few minutes for the host agent to start.

Starting the host agent

Log in as root and enter this command:

/sbin/init.d/agent start

Stopping the host agent

Log in as root and enter this command:

/sbin/init.d/agent stop

Testing the host agent connections

Before continuing, you should test the host agent connections asfollows:

1. Start the host agent as described in Starting and stopping theNavisphere Host Agent, page 27.

2. Look for any errors on the console and in the operating system logto make sure the agent started and no device errors occurred.


3. Verify that the host agent on the server can see the storage systemas follows:

a. Enter the following CLI command:naviseccli |navicli [-d device]| -h hostname port-list -hba

You cannot specify both the –d switch and –h switch.

where:

[-d device] is the device name for the storage system (onlysupported with legacy systems).

-h hostname is the IP address of the SP.

For each HBA in the server, a listing similar to the following willbe displayed. For storage systems in a SAN (shared storage)environment, the listing includes HBAs in all connected hosts.Information about each HBA:HBA UID: 10:00:00:60:B0:3E:46:AC:10:00:00:60:B0:3E:46:ACServer Name: siux134Server IP Address: 128.221.208.134HBA Model Description:HBA Vendor Description:HBA Device Driver Name:Information about each port of this HBA:SP Name: spaHBA Devicename: sp0Trusted: NOLogged In: YESSource ID: 1Defined: YESInitiator Type: 0Storage Group Name:Storage Group 134

b. In the listing, examine the information for each HBA installed inthe host to verify the path from the HBA to the SP.

Host agent status and error logging

While the system is running, the operating system tracks informationabout host agent events and host agent errors, and places thisinformation in log files on the server.


The host agent error log tracks information about the host agent’sstartup, the host agent shutdown, and errors that might occur, such asthe host agent’s inability to access a device in the configuration file. Ifproblems occur, log files are a good place to start your troubleshooting.

Host agent events and errors are logged in /var/adm/syslog/syslog.log.

Host agent events are also recorded in the /etc/log/agent.log file.


Installing and removing the Navisphere Server Utility

This section describes how to install the Navisphere Server Utility.

Installing the Navisphere Server Utility on an HP-UX server

EMC recommends that you install the most recent version of theNavisphere Server Utility software that is appropriate for yourconfiguration. You can download the most recent version from thesoftware download page on the Powerlink website. You can also installthe software from the server support CD; however, the CD may notcontain the most recent version for your configuration.


2. If an earlier version of the server utility is installed on the server,remove it before continuing.

To verify if the server utility is installed, enter the /usr/sbin/swlistcommand to get a list of the currently installed software.



b. Select the appropriate Navisphere Server Utility version anddownload the zip file.


d. Install the HOSTUTIL.dep file on the HP-UX server.

4. To install the software from the server support CD, do the following:

a. Insert the server support CD in the server’s drive.


mkdir /cdrom




ioscan -funC disk





e. Execute the following command to install the source depot:

/usr/sbin/swinstall -s /cdrom/hpux/HOSTUTIL.dep -x \mount_all_filesystems=false HOSTUTIL

f. At the command prompt (#), unmount the CD.

umount /cdrom

If you installed the server utility from the CD, remove the CDfrom the server’s CD drive.

Removing the server utility on an HP-UX server


2. Execute the following command to remove the server utility:

/usr/sbin/swremove -x mount_all_filesystems=false HOSTUTIL

The removal process begins. The removal process is complete whenthere is no error and the following message is displayed:

END swremove SESSION


Running the Navisphere Server Utility

This section describes how to start and use the server utility. You canrun the server utility from the server or from the server support CD.

Starting the Navisphere Server Utility on an HP-UX server

1. Open an hpterm window.

2. Navigate to the Navisphere bin directory:

cd /opt/Navisphere/bin

3. Run the server utility:

./naviserverutil

Starting the Navisphere Server Utility on an HP-UX server from the CD

1. In the server’s drive, insert the server support CD that shippedwith your storage system.

2. At the command prompt (#) in an hpterm window, create a CDdirectory:

mkdir /cdrom

3. Identify the device file:

ioscan -funC disk

This command lists all recognized CD drives and their associateddevice files. The filename will be similar to /dev/dsk/c1t2d0.

4. Mount the CD drive: mount /dev/dsk/device_filename /cdrom

where device_filename is the device filename from step 3.

For example, mount /dev/dsk/c1t2d0 /cdrom.

5. Navigate to the HP-UX directory:


cd /cdrom/hpux

6. Run the server utility:

./naviserverutil

Using the Navisphere Server Utility

The Navisphere Server Utility allows you to perform the followingfunctions:

Update server information on the storage system

Generate a high-availablity report (not available on servers withiSCSI connections)

Updating server information on the storage system

The Update Server Information option allows you to send informationabout the server to all connected storage systems. To update serverinformation, select option 1 from the server utility’s Welcome screen,and follow the instructions on the utility.

Generating a high-availability report

The Generate high availability report option (option 3) and thenaviserverutilcli hav command determine if the server is configuredfor high availability by verifying that the server has at least oneconnection path to each storage-system SP, and that PowerPath or someother failover software, such as DMP, PV Links, or HP native failoverfor 11iV3 is running.

After the verification, the utility generates a summary report andsaves it to the server. If you issue the -upload switch with thenaviserverutilcli hav command, the utility also sends the report to thespecified storage system.

Generate a high-availability report to:

check the status of a server.

prepare for a software installation on a storage system.


For AX4 systems only — Use the -upload switch to upload the HA reportto the storage system only if you will use the Navisphere Software Assistantto install new software. We strongly recommend that you use the SoftwareAssistant, and not the -ndu install command to update your software. The-ndu install command does not perform the same pre-install validation checksas the Software Assistant. The Software Assistant is included in the NavisphereService Taskbar.

Checking the status of a serverTo periodically check the high-availability status of a server, you canselect option 3 from the server utility’s Welcome screen, and follow theinstructions on the utility to generate a high-availability report, or issuethe naviserverutilcli hav[-directory | -d outputdirectory] command.

where:

-directory | -doutputdirectory

Specifies the directory to which you want to deposit the report onthe server. This switch is required only if you are running the serverutility from the CD. Otherwise the report is automatically saved to theNavisphere Server Utility installation directory.If the server utility is installed on your server and you specify a directory,the directory you specify will override the server utility’s installationdirectory.

Preparing for a software installation on a storage systemIf you are generating a high-availability report as a prerequisite toupdating storage-system software, you need to upload this report to thestorage system prior to installing the software on the storage system.To generate and upload an HA report, issue the following commandfrom the directory in which you installed the utility:

naviserverutilcli hav -upload -ip IPaddress |-hIPaddress|network_name -user|-u username -password|-puserpassword -scope|-s scopelevel -secfilepath securityfilepath-port 443|2163 [-directory | -d outputdirectory]

where:


-ip IPaddress Specifies the IP address of an SP on the storage system to which youwill upload the report. You cannot use this switch in conjunction withthe -h switch.

-h IPaddress |network_name

Specifies the IP address or the network name of an SP on the storagesystem to which you will upload the report. You cannot use this switchin conjunction with the -ip switch.

-user | -uusername

Specifies the login name for the storage system. You must use this switchin conjunction with the -password | -p and -scope | -s switches. Youcannot use this switch in conjunction with the -secfilepath switch.

-password | -puserpassword

Specifies the password required for access to the storage system. Youmust use this switch in conjunction with the -user | -u and -scope | -sswitches. You cannot use this switch in conjunction with the -secfilepathswitch.

-scope | -sscopelevel

Specifies the level of access this username and password has to thestorage system: 0 = global; 1 = local; 2 = LDAP. You must use this switchin conjunction with the -user | -u and -password | -p switches. Youcannot use this switch in conjunction with the -secfilepath switch.

-secfilepathsecurityfilepath

Searches the security file for the specified IP address. If the utility doesnot find the specified IP address, then the utility will use the default entryin the security file.A security file is required to run this switch. For information on how tocreate a security file, refer to the EMC Navisphere Command Line (CLI)Reference guide.You cannot use this switch in conjunction with the -user | -u, -password |-p , and -scope | -s switches.

-port 443 | 2163 Specifies the Navisphere Management Server port number. The defaultis 443.

-directory | -doutputdirectory

Specifies the directory to which you want to deposit the report onthe server. This switch is required only if you are running the serverutility from the CD. Otherwise the report is automatically saved to theNavisphere Server Utility installation directory.If the server utility is installed on your server and you specify a directory,the directory you specify will override the server utility’s installationdirectory.

After uploading the HA reportIn addition to running the server utility to validate server highavailability, we strongly recommend that you perform the followingmanual checks.


Verify support of software and hardware — Make sure thatyou have verified that all software and hardware is supportedaccording to the EMC E-Lab™ Interoperability Navigator andsupport matrices.

This tool does not verify that you are running supported switch firmware,nor that you are using redundant switches (recommended).

Upgrading storage–system software — If you are about to performa storage-system online software upgrade or you added an HBA, aLUN, or changed connectivity (added a path or changed zoning):

Make sure that you have validated all software and hardwarethat are supported and interoperable according to EMC E-LabInteroperability Navigator and support matrices.

Verify that all LUNs (virtual disks) that your servers will accessduring the upgrade are under path management softwarecontrol. For servers running PowerPath and DMP, see theFailover Software section on the Details tab of the report andlocate these LUNs. If they are not in the list, the server will loseaccess to those LUNs during the software upgrade.


Installing and removing the Admsnap Utility

EMC strongly recommends that you install admsnap on all serversconnected to a storage system that has the SnapView driver installed.

Important: If you are upgrading your storage system to FLARE OEversion 02.19.xxx.5.yyy or later, you must upgrade admsnap to version2.9.x or later. Before you upgrade FLARE, verify that your operatingsystem version supports admsnap version 2.9.x or later. Refer to theAdmsnap Release Notes.
