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

12 Upgrading the X9000 Software
This chapter describes how to upgrade to the latest X9000 File Serving Software release. The
management console and all file serving nodes must be upgraded to the new release at the same
time. Note the following:
• Upgrades to the X9000 Software 6.0 release are supported for systems currently running
X9000 Software 5.5.x and 5.6.x. If your system is running an earlier release, first upgrade
to the latest 5.5 release, and then upgrade to 6.0.
• The upgrade to 6.0 is supported only for agile management console configurations. If you
are using a dedicated Management Server, migrate to the latest 5.5 release if necessary,
migrate to the agile management console configuration and verify failover and failback, and
then perform the upgrade. For more information, see “Migrating to an agile management
console” (page 77).
• The upgrade procedure upgrades the operating system to Red Hat Enterprise Linux 5.5.
• If you are using Remote Replication, the local cluster and the remote cluster must both be
upgraded to the 6.0 release.
• Linux X9000 clients must be upgraded to the 6.0 release.
• Windows X9000 clients are not supported.
NOTE: During the upgrade, the support tickets collected with the ibrix_supportticket
command will be deleted. Before upgrading to 6.0, download a copy of the archive files (.tgz)
from the /admin/platform/diag/supporttickets directory.

Preparing for the upgrade
To prepare for the upgrade, complete the following steps:
1. Ensure that all nodes are up and running. To determine the status of your cluster nodes, check
the dashboard on the GUI or use the ibrix_health command.
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 management console:
ssh <server_name>
Repeat this command for each node in the cluster.
3. Note any custom tuning parameters, such as file system mount options. When the upgrade is
complete, you can reapply the parameters.
4. Stop any active Remote Replication, data tiering, or Rebalancer tasks running on the cluster.
(Use ibrix_task -l to list active tasks.) When the upgrade is complete, you can start the
tasks again.
5. The 6.0 release requires that nodes hosting the agile management be registered on the cluster
network. Run the following command to verify that nodes hosting the agile management
console have IP addresses on the cluster network:
ibrix_fm -f
If a node is configured on the user network, see “Node is not registered with the cluster network
” (page 92) for a workaround.
6. 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.
