Configuring a Hot Spare
If you have a hot spare configured and an array fails, the TeraStation immediately switches over to the hot spare. To
use a hot spare, you need a RAID 1 or RAID 5 array and an extra drive that's not part of an array.
Notes:
• All data on the hot spare drive is deleted when it is configured as a hot spare and again when it changes from a
spare to a drive in the array.
• A hot spare cannot be configured for TeraStation models with only two drives included.
