3 3.2.3 Automatic Rebuild and Manual Rebuild Automatic Rebuild One member drive fails in logical drive Waiting for spare No drive to be added or manual rebuild Any local spare drive Yes assigned to logical drive? No Any global spare drive Yes assigned to logical drive? No "Periodic Auto-Detect Failure Drive Swap Check Time" enabled? Yes Has the failed drive been Yes swapped? No Keep detecting if drive has been swapped or spare drive has been added Rebuild using the local spare drive Rebuild using the global spare drive Rebuild using the swapped drive When a member drive in the logical drive failed, the controller will first check whether there is a 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, and the "Periodic Auto-Detect Failure Drive Swap Check Time" is "Disabled," the controller will not try to rebuild unless the user applies a forced manual rebuild. When the "Periodic Auto-Detect Failure Drive Swap Check Time" is enabled (i.e., a check time interval has been selected), the controller will detect whether or not the failed drive has been swapped (by checking the failed drive's channel/ID). Once the failed drive has been swapped, the rebuild will begin immediately. If the failed drive is not swapped but a local spare drive is added to the logical drive, rebuilding will begin with the spare drive. 20 ASUS PCI-DA2100/PCI-DA2200 User's Manual
