Upgrading Firmware on Arrays That Do Not Support Submirrored Data

In a partner-pair configuration, it is possible to have non-mirrored data; however, this requires that you shut down the cluster when upgrading firmware, as described in this procedure.

1. Shut down the entire cluster.

   # scshutdown -y -g0

   For the full procedure on shutting down a cluster, see the Sun Cluster 3.0 12/01 System Administration Guide.

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

   For the list of required StorEdge T3+ array patches, see the Sun StorEdge T3 Disk Tray Release Notes. For the procedure on applying firmware patches, see the firmware patch README file. For the procedure on verifying the firmware level, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

3. Reset the arrays.

   For the procedure on resetting an array, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

4. Boot all nodes back into the cluster.

   ok boot

   For the full procedure on booting nodes into the cluster, see the Sun Cluster 3.0 12/01 System Administration Guide.

5. On one node connected to the partner-group, use the format command to verify that the array controllers are rediscovered by the node.

   # format
