Shutting Down and Restarting an Array

A PS5000 array includes redundant, hot-swappable disks, power supplies, and
control modules (if 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.
To shut down an array, follow these steps:
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.
• Use the null modem cable shipped with the array to connect Serial Port 0
on the active control module (ACT LED is green) to a console or a
computer running a terminal emulator.
