How to Replace a Chassis

Use this procedure to replace a storage array chassis in a running cluster. This procedure assumes that you want to retain all FRUs other than the chassis and the backplane. To replace the chassis, you must replace both the chassis and the backplane. These components are manufactured as one part.

You must be a Sun service provider to perform this procedure. If you need to replace a storage array chassis or a storage array midplane, contact your Sun service provider.

1. Detach the submirrors on the storage array that is connected to the chassis and the midplane that you are replacing. Detach the submirrors to stop all I/O activity to this storage array.

   For more information, see your Solaris Volume Manager or Veritas Volume Manager documentation.

2. Are the storage arrays in your partner–group configuration redundant as a result of host-based mirroring?

   • If yes, proceed to Step 3.

   • If no, shut down the cluster.

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

3. Replace the chassis and the midplane.

   For the procedure about how to replace a storage array chassis and a storage array midplane, see the Sun StorEdge 6320 System Reference and Service Manual.

4. Did you shut down the cluster in Step 2?

   • If no, proceed to Step 5.

   • If yes, boot the cluster back into cluster mode.

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

5. Reattach the submirrors that you detached in Step 1 to resynchronize the submirrors.

   Caution –

   The world wide numbers (WWNs) change as a result of this procedure. You must reconfigure your volume manager software to recognize the new WWNs.
