Disk Drive Led Indicator Usage - Overland Storage SnapServer Administrator's Manual

SnapServer 7.0 Administrator's Guide
• RAID 0 set (nonredundant) – You cannot add a drive to a RAID 0 set. To
reconfigure a RAID 0 set, you must delete the RAID set and then recreate it.
• RAID 1 (redundant) – You can add a new drive to a RAID set 1 as either a spare or
as a new member. Adding a disk drive to a RAID set 1 does not add storage capacity.
The new member simply creates an additional copy of the original drive.
• RAID 5, 6, or 10 set (redundant) – You can add a spare to a RAID 5, 6, or 10 set.

Reintegrate Orphaned Disk Drives
An orphan disk drive occurs in the following circumstances: (1) a working drive from a
RAID set is accidentally removed from the server; or (2) the RAID set or system is started
with a drive missing. In either case, the drive becomes suspect and is considered an orphan.
To remedy the problem, click on the RAID set in the Storage > RAID Sets page, then click the
Repair link next to the drive in question.
