How to Upgrade Storage Array Firmware When Not Using Mirroring

In a partner-pair configuration, you can have nonmirrored data. However, this configuration requires you to shut down the cluster when upgrading firmware.

Steps

1. Shut down the entire cluster.

   For the procedure about how to shut down a cluster, see your Sun Cluster system administration documentation.

2. Apply the controller, disk drive, and UIC firmware patches.

   • For the list of required storage array patches, see the Sun StorEdge 3900 and 6900 Series Reference Manual.

   • For the procedure about how to apply firmware patches, see the firmware patch README file.

   • For the procedure about how to verify the firmware level, see the Sun StorEdge 3900 and 6900 Series Reference Manual.

   • For a URL to this storage documentation, see Related Documentation.

3. If you have not already done so, reset the storage arrays.

   • For the procedure about how to reset a storage array, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

   • For a URL to this storage documentation, see Related Documentation.

4. Boot all nodes back into the cluster.

   For more information on booting nodes, see your Sun Cluster system administration documentation.

5. On one node connected to the partner-group, verify that the storage array controllers are visible to the node.
