Fig. 11.1 Logical Drive Expansion
RAID levels supported: RAID 0, 1, 3 and 5
Expansion can be performed on logical drives or logical volumes under the following condi-
tions:
1. There is unused capacity in a logical unit
2. Capacity is increased by using member drives of larger capacity
Data is recalculated and distributed to drive members or members of a logical volume. Upon
the completion of the process, the added or the previously unused capacity will become a
new partition. The new partition must be made available through host LUN mapping in order
for a host adapter to recognize its presence.
