Sun Cluster 3.0-3.1 With Sun StorEdge 3510 or 3511 FC RAID Array Manual

ProcedureHow to Replace a Chassis in a Running Cluster

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.

Steps

  1. To stop all I/O activity to this storage array, detach the submirrors that are connected to the chassis you are replacing.

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

  2. Is this storage array made redundant by host-based mirroring?

    • If yes, proceed to Step 3.

    • If no, shut down the cluster.

      For the full procedure on shutting down a cluster, see the Sun Cluster system administration documentation.

  3. Replace the chassis and backplane.

    For the procedure on replacing a chassis, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.

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

    • If no, proceed to Step 5.

    • If yes, boot it back into cluster mode.

      For the full procedure on booting a cluster, see the Sun Cluster system administration documentation.

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

    Caution – Caution –

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