6.0 HP X9320 Network Storage System Administrator Guide (AW542-96009, December 2011)

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 93).
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 90).
10. If you received a new license from HP, install it as described in the “Licensing chapter in this
guide.
After the upgrade
Complete the following steps:
1. Run the following command to rediscover physical volumes:
ibrix_pv -a
2. Apply any custom tuning parameters, such as mount options.
3. Remount all file systems:
ibrix_mount -f <fsname> -m </mountpoint>
4. Re-enable High Availability if used:
ibrix_server -m
5. Start any Remote Replication, Rebalancer, or data tiering tasks that were stopped before the
upgrade.
