add capacity

The add capacity command expands the capacity of a drive pool by adding a new
unassigned drive or drives to the pool. The number of drives you add to the pool
is dependant on the RAID level configured on your system. For RAID levels 1 and
10, you add two drives to the pool at a time. If you are operating a RAID level of
0 or 5, you add one at a time. If the capacity of the new drive is less than the
capacity of the smallest drive in the pool, the system generates an error. However,
if the capacity of the new drive is more than the capacity of the smallest drive in
the pool, the system generates a warning.
Command arguments:
<CLI> add capacity –pool name –drivelist <[ENCLOSURE]:[TRAY]>
<[ENCLOSURE]:[TRAY]> .. <[ENCLOSURE]:[TRAY]>
Where:
v name - Defines the pool name.
v [ENCLOSURE]:[TRAY] - Specifies the drive bay number by enclosure number and
Example:
<CLI> add capacity –pool Group0 –drivelist 1:3
