Chapter 3 Functional Descriptions 19 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 ther[...]

User’s Guide 20 If neither Local Spare Drive nor 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 Once the failed drive has been replaced by a new drive/used drive, it starts to rebuild using the replaced drive.
