Hot key information displays at the bottom of the screen. The hot key functions are:

Display the logical drives that have been configured.
Designate the selected drive as a hot spare.
3. Press the arrow keys to choose specific physical drives.
4. Press the spacebar to associate the selected physical drive with the current array.
The indicator for the selected drive changes from READY to ONLINE A[array
number]-[drive number]. For example, ONLINE A2-3 means disk drive 3 in array
2.
5. Add physical drives to the current array as desired.
Try to use drives of the same capacity in a specific array. If you use drives with
different capacities in an array, all drives in the array are treated as if they have the
capacity of the smallest drive in the array.
The number of physical drives in a specific array determines the RAID levels that
can be implemented with the array.
RAID 0 requires one or more physical drives.
RAID 1 requires exactly two physical drives.
RAID 5 requires at least three physical drives.
