Description
The name of each RAID.
The current condition of the RAID:
• OK – The RAID is functioning properly.
• OK–Spare Missing – The RAID is functioning properly after a
repair and rebuild. Because the local spare was consumed to

replaced to restore the RAID to its proper configuration and
provide the full protection by one or more local spares.
Alternately, you can click the link to reset the RAID spare count;

a drive failure.
• Resync – A device repair operation is in progress.
• Failed – The RAID is offline.

was configured.
