How to Replace an Array Chassis in a Running Cluster

Use this procedure to replace a StorEdge T3/T3+ 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 because these components are manufactured as one part.

Only trained, qualified Sun service providers should use this procedure to replace a StorEdge T3/T3+ array chassis. This procedure requires the Sun StorEdge T3 and T3+ Array Field Service Manual, which is available to trained Sun service providers only.

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

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

2. Are the arrays in your partner-pair configuration made redundant by host-based mirroring?

   • If yes, go to Step 3.

   • If not, shutdown the cluster.

     # scshutdown -y -g0

3. Replace the chassis/backplane.

   For the procedure on replacing a StorEdge T3/T3+ chassis, see the Sun StorEdge T3 and T3+ Array Field Service Manual. (This manual is available to trained Sun service providers only.)

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

   • If not, go to Step 5.

   • If you did shut down the cluster, boot it back into cluster mode.

     {0} ok boot

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

   Caution -

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