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

13. 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 123).
Performing the upgrade manually
This upgrade method is supported only for upgrades from IBRIX software 6.x to the 6.2 release.
Complete the following steps:
1. To obtain the latest HP IBRIX 6.2.1 (pkg-full.ISO) ISO image, register to download the
software on the HP StoreAll Download Drivers and Software web page.
Mount the ISO image on each node and copy the entire directory structure to the /local/
ibrix directory on the disk running the OS.
The following is an example of the mount command:
mount -o loop
/local/pkg/ibrix-pkgfull-FS_6.2.374+IAS_6.2.374-x86_64.iso /mnt
2. Change directory to /local/ibrix on the disk running the OS and then run chmod -R
777 * on the entire directory structure.
3. Run the following upgrade script:
./ibrixupgrade —f
The upgrade script automatically stops the necessary services and restarts them when the
upgrade is complete. The upgrade script installs the Fusion Manager on all file serving nodes.
The Fusion Manager is in active mode on the node where the upgrade was run, and is in
passive mode on the other file serving nodes. If the cluster includes a dedicated Management
Server, the Fusion Manager is installed in passive mode on that server.
4. Upgrade Linux 9000 clients. See “Upgrading Linux 9000 clients” (page 120).
5. 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. 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 125).
3. Run the following command to rediscover physical volumes:
ibrix_pv -a
4. Apply any custom tuning parameters, such as mount options.
5. Remount all file systems:
ibrix_mount -f <fsname> -m </mountpoint>
6. Re-enable High Availability if used:
ibrix_server -m
7. Start any Remote Replication, Rebalancer, or data tiering tasks that were stopped before the
upgrade.
