Purpose
The working status of array includes Functional, Degraded and Offline. By viewing
the array status, you can take immediate and proper maintenance for the disks so as
to ensure the high security and reliability of the data stored in the disk array.
When there is no disk loss in the array, the working status of array will change to
Functional; when the number of lost disks has exceeded the limit, the working status
of array will change to Offline; in other conditions, the working status is Degraded.
When the virtual disk is in Degraded status, you can restore it to Functional by array
rebuilding.
