How to Upgrade Controller Module Firmware in a Running Cluster

Use this procedure to upgrade firmware in a controller module in a running cluster. Use either the online or the offline method to upgrade your NVSRAM firmware. The method that you choose depends on your firmware.

Steps

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 an offline method. Use one of the following procedures.

     • If the data on your controller module is mirrored on another controller module, use the procedure in Step 2.

     • If the data on your controller module is not mirrored on another controller module, use the procedure in Step 3.

2. Use this step if you are upgrading the NVSRAM and other firmware files on a controller module. This controller module must have mirrored data.

   1. Halt all activity to the controller module.

      For more information, see your Solstice DiskSuite/Solaris Volume Manager 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 controller module.

      For more information, see your Solstice DiskSuite/Solaris Volume Manager 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. This controller module must not have mirrored data.

   1. Shut down the entire cluster.

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

   2. Boot one node that is attached to the controller module into noncluster mode.

      For the procedure about how to boot a node in noncluster mode, see your Sun Cluster system administration documentation.

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

   4. Boot both nodes into cluster mode.

      For more information about how to boot nodes, see your Sun Cluster system administration documentation.

      This step completes the firmware upgrade.
