6.3 HP StoreAll 9300/9320 Storage Administrator Guide (AW549-96072, June 2013)

NOTE:
• Verify that the root partition contains adequate free space for the upgrade. Approximately 4
GB is required.
• Be sure to enable password-less access among the cluster nodes before starting the upgrade.
• Do not change the active/passive Fusion Manager configuration during the upgrade.
• Linux StoreAll clients must be upgraded to the 6.x release.
Online upgrades for StoreAll software 6.x to 6.1
Online upgrades are supported only from the StoreAll 6.x release. Upgrades from earlier StoreAll
releases must use the appropriate offline upgrade procedure.
When performing an online upgrade, note the following:
• File systems remain mounted and client I/O continues during the upgrade.
• The upgrade process takes approximately 45 minutes, regardless of the number of nodes.
• The total I/O interruption per node IP is four minutes, allowing for a failover time of two minutes
and a failback time of two additional minutes.
• Client I/O having a timeout of more than two minutes is supported.
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. Ensure that High Availability is enabled on each node in the cluster.
3. 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 Fusion Manager:
ssh <server_name>
Repeat this command for each node in the cluster and verify that you are not prompted for a
password at any time.
4. Ensure that no active tasks are running. 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 6.1 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 Fusion Manager
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 21) for a workaround.
Performing the upgrade
The online upgrade is supported only from the StoreAll 6.x to 6.1 release. Complete the following
steps:
1. Obtain the latest HP StoreAll 6.1 ISO image from the StoreAll software dropbox. Contact HP
Support to register for the release and obtain access to the dropbox.
2. Mount the ISO image and copy the entire directory structure to the /root/ibrix/ directory
on the disk running the OS.
3. Change the permissions of all components in the /local/ibrix/ directory structure by
entering the following command:
chmod -R 777 /local/ibrix/
