C.2.4 Hot Spares
A hot-spare disk drive is a disk drive that is defined for automatic use if a disk drive within an array fails. The hot-spare must have a
storage capacity greater than or equal to that of the smallest member of an array. You can define as many hot spares as you want.
Any RAID-1 and RAID-5 array on an adapter can use the hot-spare disk drives on that adapter.
If a disk drive within an array fails, at the next write operation to the array, the adapter automatically uses a hot spare instead of the
failed disk drive, and rebuilds the data that was on the failed disk on to the hot spare.
