11.3 Mode 1 Expansion:

Adding Drives to a Logical Drive

Use drives with the same capacity as the original drive members. Once completed, the added

capacity will appear as another partition (new partition). Data is automatically re-striped

across the new and old members during the add-drive process. See the diagram below to get

a clear idea:

Fig. 11.2 Expansion by Adding Drive

RAID levels supported: RAID 0, 1, 3 and 5.

The new partition must be made available through a host ID/LUN.

Add Drive Procedure

First select from the Main Menu, “View and Edit Logical Drive,” and select a logical drive to

add a new drive to. The drive selected for adding should have a capacity no less than the orig-

inal member drives. If possible, use drives of the same capacity because all drives in the array

are treated as though they have the capacity of the smallest member in the array.
