Configuring a Hot Spare
Id you have a hot spare condigured and an array dails, the TeraStation immediately switches over to the hot spare. To use a
hot spare, you need an extra drive that’s not part od any array and a RAID 1, RAID 10, RAID 5, RAID 51, RAID 6, or RAID 61
array.
Note:
All data on the hot spare drive is deleted when it is condigured as a hot spare and again when it changes drom
a spare to a drive in the array.
