Array Functional
When your array is first created, it will display Functional status.
If you have enabled Scheduled Synchronization, you will occasionally notice that
your array is Synchronizing. Then it returns again to Functional.
If your array encounters a problem with a disk drive, it will display Critical status.
This indicates that your array requires your attention in order to return to
Functional.
When a disk drive fails on a non-fault-tolerant (RAID 0) array, the result is an
Offline status.
