Array Expansion
12-3
Expand Logical Drive: Re-Striping
Figure 12 - 1 Logical Drive Expansion
RAID levels supported: RAID 0, 3, and 5
Expansion can be performed on logical drives or logical volumes
under the following conditions:
1. There is an unused capacity in a logical unit
2. Capacity is increased by using member drives of larger capacity
(see Copy and Replace in the discussion below)
Data is recalculated and distributed to drive members or members
of a logical volume. On 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.
