Adding a Spare Drive
To add a spare drive to an array, the array controller must have an attached drive that
is either unassigned or is assigned as a spare to another array. You can assign a spare
to as many arrays as you want, or you can assign a separate spare to each array.
When you select
Assign Spare
, only drives that qualify will be displayed (for
example, drives with too small a capacity will not be listed). If a drive that you
expect to see is not listed, press the
Tab
key to switch to the physical drive view and
check the capacity of the drive.

Logical Configuration View

then press the
