This ensures that a proper failover sequence is used, which includes stopping all I/O operations and writing any data in write cache to disk. If the Storage Controller in each controller module is shut down, hosts cannot access the system's data. Perform a shut down before removing a controller module or powering down the system.

If this parameter is omitted, the command affects the controller being accessed. Example Shut down the Storage Controller in controller A: # shutdown a Info: Shutting down SC a...
