Configuring a Hotspare

Hotspares are physical drives that are powered up with the RAID drives and usually are
placed in a standby, or hotspare, state. The drive to be made a hotspare must have the same
or greater capacity than the other drives in the RAID array.
NOTE A 4 GB drive will not function correctly as a hotspare for a 9 GB drive. Different sizes are
allowed in a pack, but all drives in a stripe should be the same size.
