Consider using these array types only for noncritical data that does not change often and that can be easily restored from backups. I Assigning drives to the spare pool - Assign at least one drive to the spare pool that is large enough for the largest array on your system. - Regularly check which drives are spares and how much free space they have. Compare their free space to the largest array on your system. See Viewing Spare Assignments and Status on page 7-4. ❒ 7-5

■
General

Using spares does
not
replace the need for regular backups
of your data.
–
You
cannot
assign spares to nonredundant arrays (stripe set
[RAID 0] and volume set). Consider using these array
types only for noncritical data that does not change often
and that can be easily restored from backups.
■
Assigning drives to the spare pool
–
Assign at least one drive to the spare pool that is large
enough for the largest array on your system.
–
Regularly check which drives are spares and how much
free space they have. Compare their free space to the
largest array on your system. See
