1. RAID status
The status displays one of five RAID states.
•
Normal—RAID is synchronized and running. No action is required.
•
Rebuilding—A new disk has been inserted in a drive bay, or a hot spare has been activated,
and RAID is currently rebuilding. No action is required.
•
Degraded—RAID is degraded. A disk may have failed or have been removed from its bay.
For hot-swap storage systems, simply replace the faulty, inactive, uninitialized, or missing disk.
•
Off—Data cannot be stored on the storage system. The storage system is offline and flashes
in the navigation window.
•
None—RAID is unconfigured.
