6.3 HP StoreAll 9300/9320 Storage Administrator Guide (AW549-96072, June 2013)

1. If your cluster nodes contain any 10Gb NICs, reboot these nodes to load the new driver. You
must do this step before you upgrade the server firmware, as requested later in this procedure.
2. Upgrade your firmware as described in “Upgrading firmware” (page 128).
3. Mount file systems on Linux StoreAll clients.
4. If you have a file system version prior to version 6, you might have to make changes for
snapshots and data retention, as mentioned in the following list:
• Snapshots. Files used for snapshots must either be created on StoreAll software 6.0 or
later, or the pre-6.0 file system containing the files must be upgraded for snapshots. To
upgrade a file system, use the upgrade60.sh utility. For more information, see
“Upgrading pre-6.0 file systems for software snapshots” (page 159).
• Data retention. Files used for data retention (including WORM and auto-commit) must be
created on StoreAll software 6.1.1 or later, or the pre-6.1.1 file system containing the
files must be upgraded for retention features. To upgrade a file system, use the
ibrix_reten_adm -u -f FSNAME command. Additional steps are required before
and after you run the ibrix_reten_adm -u -f FSNAME command. For more
information, see “Upgrading pre-6.1.1 file systems for data retention features” (page 161).
5. If you have an Express Query enabled file system prior to version 6.3, manually complete
each file system upgrade as described in “Required steps after the StoreAll Upgrade for pre-6.3
Express Query enabled file systems” (page 19).

Preparing for the upgrade
To prepare for the upgrade, complete the following steps:
1. Make sure you have completed all steps in the upgrade checklist (Table 1 (page 9)).
2. Verify that ssh shared keys have been set up. To do this, run the following command on the
node hosting the active instance of the agile Fusion Manager:
ssh <server_name>
Repeat this command for each node in the cluster.
3. Verify that all file system node servers have separate file systems mounted on the following
partitions by using the df command:
• /
• /local
• /stage
• /alt
4. Verify that all FSN servers have a minimum of 4 GB of free/available storage on the /local
partition by using the df command .
5. Verify that all FSN servers are not reporting any partition as 100% full (at least 5% free space)
by using the df command .
6. Note any custom tuning parameters, such as file system mount options. When the upgrade is
complete, you can reapply the parameters.
7. Stop all client I/O to the cluster or file systems. On the Linux client, use lsof </mountpoint>
to show open files belonging to active processes.
8. On the active Fusion Manager, enter the following command to place the Fusion Manager
into maintenance mode:
<ibrixhome>/bin/ibrix_fm -m nofmfailover -P -A
9. On the active Fusion Manager node, disable automated failover on all file serving nodes:
<ibrixhome>/bin/ibrix_server -m -U
