Chapter 16: Solving Problems ● 148 Failed Disk Drive Protected by a Hot Spare When a logical drive is protected by a hot spare, if a disk drive in that logical drive fails the hot spare is automatically incorporated into the logical drive and takes over for the failed drive. For instance, when a disk drive fails in the RAID 5 logical drive shown in the example below, the logical drive is automatically rebuilt (its data is reconstructed) using the hot spare in place of the failed drive. You can't access the logical drive until the rebuilding is complete. Disk drive shows Failed status... ...hot spare takes over... ...and logical drive is rebuilt with hot spare Note: In the example above, the color of the hot spare changed from light-blue to dark-blue, showing that it is now part of a logical drive. To recover from the failure: 1 Remove and replace the failed disk drive (following manufacturer's instructions). 2 If copyback is not enabled-Remove the 'hot spare' designation from the original hot spare (the disk drive that was built into the logical drive). See page 93 for instructions. Then, designate a new hot spare to protect the logical drives on that controller. If copyback is enabled-Data is automatically moved back to its original location once the controller detects that the failed drive has been replaced. No action is required. See Enabling Copyback on page 98 for more information.
