3.16 Expansion
IMPORTANT:
 Before expanding logical drives, be sure to back up the data in the disks.
If an unexpected error occurs during the expansion, the data in the disks
may be lost.
 Only a RAID5 configured with three physical drives can be expanded to
one configured with four drives.
 All the physical drives should have the same capacity.
 This feature can expand the capacity of the logical drive. As seen from
the OS (Disk Management), the capacity of the HDD is larger than before.
You can use this portion by creating a new partition.
1. Click the disk array which you want to expand in the Tree View.
2. Click the arrow at the right end of the Background Activities tab in the Management Window,
and select Start Migration.
