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.
