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.
- Select any storage icon in the main
window.
- Choose Array Administration > Controller
Maintenance.
- If you are not already logged in as
ssconfig, a password prompt is displayed; type your ssconfig
password.
The Controller Maintenance Options
window is displayed.
- Click Shut Down the Controller.
