Critical & Offline Disk Arrays
A fault-tolerant disk array
—RAID 1, 1E, 5, 10, and 50—goes critical when a disk drive is removed or fails. A
RAID 6 or 60 disk array
—goes degraded when a disk drive is removed or fails and critical when two disk drives
are removed of fail.
Due to the fault tolerance of the disk array, the data is still available and online. However, once the disk array
goes critical, the disk array has lost its fault tolerance, and performance may be adversely affected.
goes critical, the disk array has lost its fault tolerance, and performance may be adversely affected.
If the fault was caused by a failed drive that was removed, the drive must be replaced by another drive, either
identical or larger, in order for the RAID system to rebuild and restore optimal configuration.

If your fault-tolerant disk array
