12.1.4 Rebuilding Array
Purpose
The working status of an 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; if 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.
