Chapter 4 RAID Modes and Drive Management
Conditions and Corrective Actions If Undetected Drives Aren't Displayed Properly
Even when you configure the NAS to show the confirmation screen if a drive being used for the RAID array cannot
be mounted, undetected drives will not be displayed under the following conditions. If you are using any of the
RAID array configurations below, follow the corrective procedure.
Conditions
RAID 10 has been configured.
Multiple arrays have been configured.
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.
