Manual Rebuild - Asus PCI-DA2100 User Manual

Manual Rebuild

When a user applies forced-manual rebuild, the controller will first
check whether there is any Local Spare Drive assigned to this logical
drive. If yes, it will automatically start to rebuild.
If there is no Local Spare Drive available, the controller will search
for a Global Spare Drive. If there is a Global Spare Drive, it will
automatically rebuild the logical drive.

If neither a Local Spare Drive nor a Global Spare Drive is available,
the controller will detect the SCSI channel and ID of the failed drive.
Once the failed drive has been replaced by a new drive/used drive, it
starts to rebuild using the replaced drive. If there is no available
drive for rebuilding, the controller will not try to rebuild again until
the user applies another forced-manual rebuild.
3.2.4 Concurrent Rebuild in RAID (0+1)
RAID (0+1) allows multiple drive failure and concurrent multiple
drive rebuild. Newly replaced drives must be scanned and set as
Local Spare Drives. These drives will be rebuilt at the same time (you
do not need to repeat the rebuilding process for each drive).
