6. Click OK.
A message is displayed that describes restart activity.
Shutting down controllers
Perform a shut down before you remove a controller module from an enclosure, or before you power off its enclosure for
maintenance, repair, or a move. Shutting down the storage controller in a controller module 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 you shut down the
storage controller in both controller modules, hosts cannot access system data.
CAUTION:
You can continue to use the CLI when either or both storage controllers are shut down, but some
information might not be available.
Perform a shutdown

2. Select the Shut Down operation, which automatically selects the Storage controller type.
3. Select the controller module to shut down: Controller A, Controller B, or both.
4. Click OK.
A confirmation panel appears.
