How to Upgrade Controller Module Firmware in a Running Cluster

Use this procedure to upgrade firmware in a StorEdge A3500/A3500FC controller module, in a running cluster. Depending on which firmware you are upgrading, you must use either the online or offline method, as described in the Sun StorEdge RAID Manager User's Guide.

1. Are you upgrading the NVSRAM firmware file?

   • If you are not upgrading the NVSRAM file, you can use the online method.

     Upgrade the firmware by using the online method, as described in the Sun StorEdge RAID Manager User's Guide. No special steps are required for a cluster environment.

   • If you are upgrading the NVSRAM file, you must use the offline method, using one of the following two procedures:

     -- If the data on your StorEdge A3500/A3500FC controller module is mirrored on another controller module, use the procedure that is described in Step 2.

     -- If the data on your StorEdge A3500/A3500FC controller module is not mirrored on another controller module, use the procedure that is described in Step 3.

2. Use this step if you are upgrading the NVSRAM and other firmware files on a controller module that has its data mirrored:

   1. Halt all activity to the StorEdge A3500/A3500FC controller module.

      For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

   2. Update the firmware files by using the offline method, as described in the Sun StorEdge RAID Manager User's Guide.

   3. Restore all activity to the StorEdge A3500/A3500FC controller module.

      For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

      This step completes the firmware upgrade.

3. Use this step if you are upgrading the NVSRAM and other firmware files on a controller module that does not have its data mirrored:

   1. Shut down the entire cluster.

      # scshutdown -y -g0 -i0

      For the full procedure on shutting down a cluster, see the Sun Cluster 3.0 U1 System Administration Guide.

   2. Boot one node that is attached to the controller module into non-cluster mode.

      ok boot -x

      For the full procedure on booting a node into non-cluster mode, see the Sun Cluster 3.0 U1 System Administration Guide.

   3. Update the firmware files using the offline method, as described in the Sun StorEdge RAID Manager User's Guide.

   4. Reboot both nodes into cluster mode.

      ok boot

      For the full procedure on booting nodes into the cluster, see the Sun Cluster 3.0 U1 System Administration Guide.

      This step completes the firmware upgrade.
