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 hard drives. Use RAID 1 instead.

In Settings, click  Drives.

Choose RAID.

Choose a RAID array.

Click Set as a hot spare.

Step through the wizard.

When the “Confirm Operation” screen opens, enter the confirmation number and click OK.

Notes: 
•  To turn the hot spare back into a normal disk, choose Set as a normal disk.
•  If a drive fails in the RAID array before it is rebooted, the hot spare will not automatically replace the failed drive. 

In this case, follow the steps below to repair the array.

(1)  In Settings, navigate to Drives - Drives.
(2)  Select the drive that was configured as a hot spare, then click Dismount Disk.
(3)  Click Rediscover Disk.
(4)  Navigate to Drives - RAID.
(5)  Select the RAID array to repair.
(6)  Select the drive that was previously configured as a hot spare, then click “Recover RAID Array”.

This will rebuild the RAID array.

With RMM, you can create or expand a RAID array without erasing the data on the drives.
