Use “Expand RAID Set” function to add disk to a RAID set. The additional
capacity can be used to enlarge the last volume set size or to create another
volume set. The “Modify Volume Set” function can support the “Volume
Modification” function. To expand the last volume set capacity, move the cursor
bar to the “Capacity” item and entry the capacity size. When finished the above
action, press the ESC key and select the Yes option to complete the action. The
last volume set starts to expand its capacity.
To expand an existing volume noticed:
 Only the last volume can expand capacity.
 When expand volume capacity, you can’t modify stripe size or modify
RAID level simultaneously.
 You can expand volume capacity, but can’t shrink volume capacity size.
 After volume expansion, the volume capacity can't be decreased.
For over 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 LBA64 mode. Please make sure your OS
supports LBA64 before expand it.
