When one hard drive member of a RAID 5 volume has failed or is disconnected, the RAID 5 volume is reported as "Degraded." When two or more hard drive members have failed or are disconnected, the volume is reported as "Failed."

If one of these scenarios occurs, refer to the appropriate procedure below to recover.

Degraded RAID 5 Volume

Missing Member

1. Make sure the system is powered off.
2. Reconnect the missing hard drive.
3. Power on the system. The rebuild will occur automatically.

Failed Member

1. Make sure the system is powered off.
2. Replace the failed hard drive with new hard drive that is of equal or greater capacity.
3. Power on the system.
4. After the operating system is running, select the Intel® Matrix Storage Console from the Start Menu or click on the Intel® Matrix Storage Manager tray icon.
5. Click on the View menu and select Advanced Mode.
6. Right-click on the non-RAID hard drive in the device tree and select Rebuild to this Hard Drive.

Failed RAID 5 Volume

Failed Members

Note: When more than one hard drive member of a RAID 5 volume has failed, the RAID 5 volume cannot be recovered and any data on the RAID 5 volume is lost. This procedure deletes the failed RAID 5 volume.

1. Make sure the system is powered off.
2. Replace the failed hard drives with new hard drives that are 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 5 volume status as "Failed," prompting you to press Ctrl-I to enter the user interface.
4. Press Ctrl-I to enter the "Main Menu."
5. Select option 2. Delete RAID Volume in the main menu.
6. In the "Delete Volume Menu," use the up and down arrow keys to select the failed RAID 5 volume.
7. Press the Delete key to delete the volume.
8. Press Y to confirm the deletion.
9. Create a new RAID 5 volume.
10. You will then need to reinstall the operating system on the new volume.
