Degraded Status

A mode of operation for a RAID 1, 3, or 5 logical drive when one drive fails in an array. The controller continues to function in the degraded mode because it uses the data and redundancy on the drives that are still operational. This enables you to continue reading and writing to the logical drive without losing data and to reconstruct the data after you replace the failed drive. The Degraded logical drive icon displayed in the Logical View is .

If a hot spare is configured and it takes over for the failed drive, the logical drive remains in an Optimal status and still shows a single failed drive.
