function allows the users to add disk drives to the RAID set that have already been created.

"Select SAS/SATA Drives For Raid Set Expansion" screen appears.
2. Select the target RAID set by clicking on the appropriate check box. Select the target disk by
clicking on the appropriate check box.
3. 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.
4. 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:
Once the "Expand RAID Set" process has started, user cannot stop it. The process must be
•
completed.

•
occur after the RAID set expansion completes.
RAID 30/50/60 does not support the "Expand RAID Set".
