6.2 HP IBRIX 9300/9320 Storage Administrator Guide (AW549-96049, December 2012)

Upgrading the file serving nodes
After the management console has been upgraded, complete the following steps on each file
serving node:
1. Move the <installer_dir>/ibrix directory used in the previous release installation to
ibrix.old. For example, if you expanded the tarball in /root during the previous IBRIX
installation on this node, the installer is in /root/ibrix.
2. Expand the distribution tarball or mount the distribution DVD in a directory of your choice.
Expanding the tarball creates a subdirectory named ibrix that contains the installer program.
For example, if you expand the tarball in /root, the installer is in /root/ibrix.
3. Change to the installer directory if necessary and execute the following command:
./ibrixupgrade -f
The upgrade automatically stops services and restarts them when the process completes.
4. When the upgrade is complete, verify that the IBRIX software services are running on the node:
/etc/init.d/ibrix_server status
The output should be similar to the following example. If the IAD service is not running on your
system, contact HP Support.
IBRIX Filesystem Drivers loaded
ibrcud is running.. pid 23325
IBRIX IAD Server (pid 23368) running...
5. Execute the following commands to verify that the ibrix and ipfs services are running:
lsmod|grep ibrix
ibrix 2323332 0 (unused)
lsmod|grep ipfs
ipfs1 102592 0 (unused)
If either grep command returns empty, contact HP Support.
6. From the management console, verify that the new version of IBRIX software FS/IAS has been
installed on the file serving nodes:
<ibrixhome>/bin/ibrix_version -l –S
Completing the upgrade
1. Remount all file systems:
<ibrixhome>/bin/ibrix_mount -f <fsname> -m </mountpoint>
2. From the management console, turn automated failover back on:
<ibrixhome>/bin/ibrix_server -m
3. Confirm that automated failover is enabled:
<ibrixhome>/bin/ibrix_server -l
In the output, HA displays on.
4. From the management console, perform a manual backup of the upgraded configuration:
<ibrixhome>/bin/ibrix_fm -B
5. Verify that all version indicators match for file serving nodes. Run the following command from
the management console:
<ibrixhome>/bin/ibrix_version –l
If there is a version mismatch, run the /ibrix/ibrixupgrade -f script again on the
affected node, and then recheck the versions. The installation is successful when all version
indicators match. If you followed all instructions and the version indicators do not match,
contact HP Support.
6. Verify the health of the cluster:
<ibrixhome>/bin/ibrix_health -l
