Spare Drive Management
If you have an unassigned physical drive, you can assign it as a spare
drive. A spare drive is a physical drive designated to replace a failed
physical drive in a RAID Volume.
Spare drive support depends on which NAS model you have.
DNS-1250-04 supports up to four physical drives.
In the event of the failure of a physical drive within a RAID 1 or
three-drive RAID 1E, or RAID 5 Volume, the spare drive is activated
to replace the failed physical drive.
A spare drive is not available for a RAID 10 Volume because RAID
10 requires all four physical drives.
DNS-1250-06 supports up to six physical drives.
In the event of the failure of a physical drive within any Volume
except RAID 0 and RAID 6, the spare drive is activated to replace the
failed physical drive.
A spare drive is not available for a RAID 6 Volume because RAID 6
requires all six physical drives.
