13.2 Rebuilding Array

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.
