7. If you want to, add a spare disk to protect against a failed disk. If you
add a spare disk to storage unit 1, that spare is assigned to any other
storage units that use the same disks as storage unit 1, in our case,
disks 101, 102, 108, and 109. You can assign one disk drive to be a spare
for several arrays of disks. Add a spare disk, as shown in Example 4-11.
