In hot-spare mode, the 4-drive TeraStation will
automatically switch over to a standby disk if
a disk in an array fails. Hot spare mode works
with RAID 5 (3 hard disks) or RAID 1 arrays.
Any data on the hot-spare disk will be erased if
the array switches over to it.
To congure a hot spare, rst build a RAID 5 or
RAID 1 array. Leave at least one drive unused.
Navigate to System/Storage/RAID Array in the
Web Admin Tool and click on the RAID array
that you just created.
Check Set as Spare Disk and then click Save.
