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

2. 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.
3. Verify that all IBRIX file systems can be successfully unmounted from all FSN servers:
ibrix_umount -f fsname
Performing the upgrade
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 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:
./auto_ibrixupgrade
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. Mount file systems on Linux 9000 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 IBRIX 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 153).
• Data retention. Files used for data retention (including WORM and auto-commit) must be
created on IBRIX 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-6.0 file systems for software snapshots” (page 153).
