Notes on Spare Drives using the Easy RAID Setting (EZ)

When EZ is function is ENABLED, the auto-rebuilding to spare drive is automatic.

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.

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.
