If the status of a RAID 1 volume is Failed or Degraded, you can rebuild it through the Intel RST configuration utility. To rebuild a RAID 1 volume, ensure that at least one member drive of the RAID 1 volume works correctly. Replace the failed storage drive with a new one that has the same capacity before you rebuild a RAID 1 volume.
Enter the Intel RST configuration utility.
Select the volume that you want to rebuild under RAID Volumes. Press Enter to open the RAID VOLUME INFO window.
Select Rebuild and press Enter to open the Rebuild Volume window.
Select the drive that you want to rebuild and press Enter to initiate the rebuild process.
After you initiate the rebuild process, the Intel (R) Rapid Storage Technology window is displayed. The RAID 1 volume under rebuilding is displayed under RAID Volumes with a Rebuilding mark.
Wait a few minutes. When the rebuild process finishes successfully, the Rebuilding mark is changed to the Normal mark.
Press F10 to save changes and exit.
