Whenever the array is popwered off, you need to first shut down the controller to ensure that write cache is flushed
to disk so that the backup battery (if present) is not drained by the cache memory.
CAUTION: Shutting down the controller causes the array to stop responding to I/O requests from
the host. This might result in data loss unless all I/O activity is suspended by halting all applications
that are accessing the array, and unmounting any file systems that are mounted from the array. In redundant-controller
configurations, shutting down the controller affects all LUNs on both controllers.
