Configure Global Spare Disks

A global spare disk is a redundant disk that can automatically take the place of a failed disk in
any volume. A failed disk and a spare disk taking over do not need to have the same physical
performance characteristics because the replacement is temporary, similar to using a spare
tire on a car with a flat tire that needs to be repaired.
IMPORTANT:
Having a spare disk takes over after a failure is a temporary
solution; replace the failed disk as soon as possible.
