Hot Spare

Hot spares are used as spare drives for when drives in a RAID group fail, or when drives are in error status.

Figure: Hot Spare

Note

For RAID6-FR, because a RAID6-FR group reserves an area equivalent to one drive, data can be restored to the reserved space even if a drive fails. If the reserved area is in use and an error occurs in another drive (2nd) in the RAID group, then the hot spare is used as a spare.
