Shutting Down and Restarting an Array
A PS Series array includes redundant, hot-swappable drives, power supplies, and control modules (in a dual
control module array). You can remove a redundant component without affecting operation if a functioning
component is available. Otherwise, it is recommended that you cleanly shut down the array and turn off power
before removing a component.
Note:
When an array is shut down, any volumes with data on the array will be set offline until the array is
successfully restarted. This may affect initiators that are connected to the volumes.
