Shutting Down and Restarting an Array
A PS4000 array includes redundant, hot-swappable disk 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.
1. Do one of the following:
• Use telnet or SSH to connect to a functioning IP address assigned to a
network interface on the array. Do not connect to the group IP address.
