6.0 HP X9720 Network Storage System Administrator Guide (AW549-96034, December 2011)

1. Ensure that all nodes are up and running. To determine the status of the cluster nodes, check

the dashboard on the GUI or use the ibrix_health command.

2. Obtain the latest HP X9000 Quick Restore DVD version 6.0 ISO image from the HP kiosk at

http://www.software.hp.com/kiosk (you will need your HP-provided login credentials).

3. Unmount file systems on Linux X9000 clients.

4. Copy the .iso file onto the server hosting the current active management console.

5. Stop the CIFS, NFS and NDMP services on all nodes. Run the following commands on the

node hosting the active management console:

ibrix_server -s -t cifs -c stop

ibrix_server -s -t nfs -c stop

ibrix_server -s -t ndmp -c stop

If you are using CIFS, verify that all likewise services are down on all file serving nodes:

ps –ef | grep likewise

Use kill -9 to stop any likewise services that are still running.

If you are using NFS, verify that all NFS processes are stopped:

ps –ef | grep nfs

If necessary, use the following command to stop NFS services:

/etc/init.d/nfs stop

Use kill -9 to stop any NFS processes that are still running.

If necessary, run the following command on all nodes to find any open file handles for the

mounted file systems:

lsof </mountpoint>

Use kill -9 to stop any processes that still have open file handles on the file systems.

6. Unmount each file system manually:

ibrix_umount -f FSNAME

Wait up to 15 minutes for the file systems to unmount.

Troubleshoot any issues with unmounting file systems before proceeding with the upgrade.

See “File system unmount issues” (page 94).

7. Run the following command, specifying the absolute location of the local iso copy as the

argument:

/usr/local/ibrix/setup/upgrade <iso>

The upgrade script performs all necessary upgrade steps on every server in the cluster and

logs progress in the file /usr/local/ibrix/setup/upgrade.log. For a normal cluster

configuration, the upgrade script can take up to 20 minutes to complete. After the script

completes, each server will be automatically rebooted and will begin installing the latest

software.

8. After the install is complete, the upgrade process automatically restores node-specific

configuration information and the cluster should be running the latest software. The upgrade

process also ensures that the management console is available on all file serving nodes and

installs the management console in passive mode on any dedicated Management Servers.

If an UPGRADE FAILED message appears on the active management console, see the specified

log file for details.

9. Upgrade Linux X9000 clients. See “Upgrading Linux X9000 clients” (page 91).

10. If you received a new license from HP, install it as described in the “Licensing” chapter in this

guide.
