– Consider assigning a spare to the array that has your most
critical data. Then, consider using that disk drive only as a
spare, that is, do not use it for an array.
– When you reconfigure an array, determine if you need to
change the spare assignments. For example, if you expand the
capacity of an array and you have an assigned spare, check
that the assigned spare has enough free space for the resized
array.
– Regularly check which disk drives are spares and which
arrays they are assigned to. Check that the free space on the
spare is sufficient for the array. See Viewing Spare Assignments
and Status on page 7-7.
