How to Replace a Sun StorEdge T3 Disk Array Chassis

Use this procedure to replace a Sun StorEdge T3 disk array chassis. 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 service providers should use this procedure to replace a Sun StorEdge T3 disk array chassis.

1. Detach the submirrors on the Sun StorEdge T3 disk array connected to the chassis you want to replace to stop all I/O activity to this Sun StorEdge T3 disk array.
