6.6.4.2 Volume Set Migration
Migrating occurs when a volume set is migrating from one RAID
level to another, when a volume set strip size changes, or when
a disk is added to a RAID set. Migration state is displayed in the
volume state area of the “Volume Set Information” screen.
Note:
If the volume is RAID level 30, 50, or 60, you can not
change the volume to another RAID level. If the volume is
RAID level 0, 1, 10(1E), 3, 5, or 6, you can not change the
volume to RAID level 30, 50, or 60.
