Notes on Spare Drives using the Easy RAID Setting (EZ)
When EZ is function is ENABLED, the auto-rebuilding to spare drive is automatic.
T E C H N O L O G I E S
The degraded RAID group will start rebuilding automatically by using the existing
spare drive.
* Spare drive can be either plugged before RAID building or a new drive can be plug
as the spare drive when RAID rebuild is required.
A.
Which port acts as a spare drive?
The last drive will automatically become the spare drive.
For a 3-drive RAID5 with spare:
Drives connected to SATA ports 1~3 belong to the active RAID5 array and
drive connected to port 4 is the spare.
For a 4-drive RAID10 with spare:
Drives connected to SATA ports 1~4 belong to the active RAID10 array and
drive connected to port 5 is the spare.
R
For a 2-drive RAID1 with spare:
Drives connected to SATA ports 1& 4 belong to the active RAID1 array and
drive connected to port 5 is the spare.
B.
When will rebuild action start?
•
When the raid fails and EZ is enabled, the HPM-XA will
automatically rebuild the RAID group using the spare.
•
When the raid fails and EZ is disabled, the HPM-XA will NOT
rebuild the raid group unless you install a good drive to replace the
failed drive.
