Conguring a Hot Spare
A hot spare will automatically replace a failed drive in a RAID array. You must have an extra drive to congure a
hot spare, so it is only usable with a RAID 5 array of 3 drives or a RAID 1 array. Congure a hot spare as follows.
Note: When you change a drive from normal mode to a hot spare, or from a hot spare back to normal mode,
all data on the drive is lost. Back up any important data on the drive before changing settings.
