Degraded state of virtual disks
A redundant virtual disk is in a degraded state when one or more physical disks have failed or are inaccessible. For example, if a RAID 1
virtual disk consists of two physical disks and one of them fails or become inaccessible, the virtual disk become degraded.
To recover a virtual disk from a degraded state, you must replace the failed physical disk and rebuild it. Once the rebuilding process is
complete, the virtual disk state changes from degraded to optimal. For information on rebuilding the disk, see Performing A Manual Rebuild
Of An Individual Physical Disk.
