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

/stage, and /alt, your system was quick-restored and you can use the automated upgrade
procedure. If you do not see these mount points, proceed with the manual upgrade process.
• Automatic upgrades. This process uses separate partitioned space on the local disk to save
node-specific configuration information. After each node is upgraded, its configuration is
automatically reapplied.
• Manual upgrades. Before each server upgrade, this process requires that you save and back
up the node-specific configuration information from the server onto an external device. After
the server is upgraded, restore the node-specific configuration information manually.
NOTE: The automatic upgrade procedure can be used only if all nodes in the cluster were
originally installed with the 5.5 release. If you upgraded any nodes in the cluster from the 5.4
release to the 5.5 release, you must use the manual upgrade procedure.
The upgrade takes approximately 45 minutes for X9320 and X9720 systems with a standard
configuration.
Automatic upgrade procedure
All file serving nodes and management consoles must be up when you perform the upgrade. If a
node or management console is not up, the upgrade script will fail.
IMPORTANT: Before performing the upgrade, complete the following steps:
• Note any custom tuning parameters, such as file system mount options. When the upgrade is
complete, you can reapply the parameters.
• 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.
• 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.
Performing the upgrade
To upgrade all nodes in the cluster automatically, complete the following steps:
1. Ensure that all nodes are up and running. To determine the status of the cluster nodes, check
the dashboard on the GUI or use the ibrix_health command.
2. Obtain the latest HP X9000 Quick Restore DVD version 6.0 ISO image from the HP kiosk at
http://www.software.hp.com/kiosk (you will need your HP-provided login credentials).
3. Unmount file systems on Linux X9000 clients.
4. Copy the .iso file onto the server hosting the current active management console.
5. Stop the CIFS, NFS and NDMP services on all nodes. Run the following commands on the
node hosting the active management console:
ibrix_server -s -t cifs -c stop
nl
ibrix_server -s -t nfs -c stop
nl
ibrix_server -s -t ndmp -c stop
If you are using CIFS, verify that all likewise services are down on all file serving nodes:
ps –ef | grep likewise
Use kill -9 to stop any likewise services that are still running.
