Effects of a Hard Drive Failure
If more hard drives fail than the fault tolerance method allows, the logical drive fails. In this case, you are
likely to lose data.
2.4.2 Disk Replacement - Automatic Rebuild
Degraded RAID 1 Volume
A RAID 1 volume is reported as 'Degraded' when one of its members fails or is disconnected and data
mirroring is lost. As a result, the system can only use the functional member. To re-establish data mirroring and
restore data redundancy, refer to the procedures below.
Missing Member Drive
1. Make sure the system is powered OFF.
2. Reconnect the missing hard drive.
3. Restart the system. The rebuild will occur automatically.
Failed Member Drive
1. Make sure the system is powered OFF.
2. Replace the failed hard drive with a new one that is of equal or greater capacity.
3. Power on the system. During the system startup, the Intel® Matrix Storage Manager option ROM user
Interface will display the RAID 1 volume status as 'Degraded' (Figure 2-4).
4. After the operating system is running, select Intel® Matrix Storage Console from the Start Menu or click
the Intel Matrix Storage Manager tray icon.
5. From the View menu (circled in Figure 2-5), select 'Advanced Mode' to see a detailed view of device
storage information.
6. In the device pane, right-click on the new non-RAID hard drive and select 'Rebuild to this Hard Drive'.
Click on the RAID 1 volume in the device pane. The status in the information pane will display 'Rebuilding: %
complete'. After the rebuild is complete, the status will display 'Normal'.
