• When expand volume capacity, you can’t modify stripe size or
modify RAID revel simultaneously.
• You can expand volume capacity, but can’t reduce volume
capacity size.
• After volume expansion, the volume capacity can not be
decreased.
For greater 2TB expansion:
• If your system installed in the volume, don't expand the
volume capacity greater 2TB, currently OS can’t support boot
up from a greater 2TB capacity device.
• Expand over 2TB used 64bit LBA mode. Please make sure
your OS supports 64bit LBA before expand it.
3.7.3.4.2 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.
