For example, an existing disk array uses three,
2150 MB hard disk drives that are configured as two
RAID level-5 logical drives (one 500 MB and
1000 MB) and 2800 MB of free space. If you use the
logical drive migration procedure and add a 2150 MB
hard disk drive to increase the amount of free space,
the end result will be two RAID level-5 logical drives
(one 500 MB and one 1000 MB) and with 4950 MB
of free space.

You can increase the size of all the logical drives
proportionally in a disk array. This is useful when you
want to increase the size of the currently defined
logical drives. Refer to the following illustration.

To add a physical device:
1. Select the icon on the Tool Bar or select
Manage Disk Arrays from the Advanced pull-down
menu; then, select Logical Drive Migration. A
screen similar to the following appears.
2. Select Add Physical Drive(s).
A prompt appears requesting that you select from 1 to
3 Ready (RDY) drives to add to the existing array.
