12.2 Mode 1 Expansion:
Adding Drives to a Logical Drive
Use drives of the same capacity as that of 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:
Figure 12 - 2 Expansion by Adding Drive
RAID levels supported: RAID 0, 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 original member
drives. If possible, use drives of the same capacity because all
drives in the array is treated as though they have the capacity of the
smallest member in the array.
