Example
Following is an example to explain the Transition function.
In the example above, there is a four-drive RAID 5 disk array and a global spare drive. Physical drives
1,2,3,and4belongtothediskarray.Physicaldrive5remainsuncongured.Physicaldrive6isa
revertible spare drive.
If a physical drive fails in a disk array and there is a spare drive of adequate capacity available, the
controller automatically rebuilds the array using the spare drive. In this example, physical drive 3 failed
and the array is rebuilt using physical drive 6, the revertible spare drive.
