How to Replace a Controller

If the RAID storage array is configured with dual controllers, see the Sun StorEdge 3000 Family FRU Installation Guidey for controller replacement procedures. If the RAID storage array is configured with a single controller, perform the procedure below to ensure high availability.

Steps

1. Detach the submirrors on the RAID storage array that are connected to the controller. This controller is the controller that you are replacing. Detach the submirrors to stop all I/O activity to the RAID storage array.

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

2. Replace the controller.

   For the procedure about how to replace a controller, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.

3. Reattach the submirrors to resynchronize the submirrors.

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