2.

Click Prepare to Remove, then click OK to continue.

When the lights on the disk you have prepared to remove stop blinking, the disk
is ready to be physically removed.The disk will not be listed in the array group.

Rescan Controller

This rescan Controller command can be used to check whether there are any new
disks that were attached after a configuration was set.

1.

Right-click the controller you want to rescan.

2.

Click Rescan Controller.

After the operation is finished, the console is refreshed and the newly attached
disks (if there are any) will appear under the Array Disk Group object and under
the controller object.

Flush Cache

The Flush Cache command forces the PERC 2/DC controller to write the contents of
cache memory onto the virtual disks. You may want to use this option if you find your
application or disks in an unstable condition.
