6.5.3 Expand Raid Set

Instead of deleting a RAID set and recreating it with additional
disk drives, the "Expand Raid Set" function allows the users to
add disk drives to the RAID set that have already been created.
To expand a RAID set:
Select the "Expand Raid Set" option. If there is an available disk,
then the "Select SAS/SATA Drives For Raid Set Expansion" screen
appears.
Select the target RAID set by clicking on the appropriate radio
button. Select the target disk by clicking on the appropriate check
box.
Click on the "Submit" button to start the expansion on the RAID
set.
The new additional capacity can be utilized by one or more volume
sets. The volume sets associated with this RAID set appear for
you to have chance to modify RAID level or stripe size. Follow the
instruction presented in the "Modify Volume Set " to modify the
volume sets; operation system specific utilities may be required
to expand operating system partitions.
Note:
1. Once the "Expand Raid Set" process has started, user can
not stop it. The process must be completed.
2. If a disk drive fails during RAID set expansion and a hot
spare is available, an auto rebuild operation will occur after
the RAID set expansion completes.
3. RAID 30/50/60 does not support the "Expand Raid set".
4. RAID set expansion is a quite critical process, we strongly
recommend customer backup data before expand. Unex-
pected accident may cause serious data corruption.
