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:
1. Select the "Expand Raid Set" option. If there is an available disk, then the "Select
SAS/SATA Drives For Raid Set Expansion" screen appears.
2. Select the target RAID set by clicking on the appropriate radius button. Select the target
disk by clicking on the appropriate check box.
3. Press the Yes key 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:
Once the "Expand RAID Set" process has started, user cannot stop it. The process must
•
be completed.
If a disk drive fais during RAID set expansion and a hot spare is available, an auto rebuild
•
will occur after the RAID set expansion completes.
RAID 30/50/60 does not support the "Expand RAID Set".
•
RAID set expansion is a critical process, Sans Digital strongly recommend customer
•
backup data before expand. Unexpected accident may cause unrecoverable data
corruption.
Migration occurs when a disk is added to a RAID set. Migrating state is displayed in the RAID
state area of "The Raid Set Information" screen when a disk is being added to a RAID set.
Migrating state is also displayed in the associated volume state area of the "Volume Set
Information" which belongs this RAID set.
