A RAID 10 volume will be reported as Degraded if one of the following conditions exists:

• One of the member hard drives fails or is disconnected.
• Two non-adjacent member hard drives fail or are disconnected.

A RAID 10 volume will be reported as Failed if one of the following conditions exists:

• Two adjacent member hard drives fail or are disconnected.
• Three or four member hard drives fail or are disconnected.

To restore the volume, refer to the applicable procedure below:

Note: Recovering a RAID 10 volume (from the failed state to the degraded state) requires that at least two non-adjacent member hard drives be present and normal.

Degraded RAID 10 Volume

Missing Member(s)

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

Failed Member(s)

1. Make sure the system is powered off.
2. Replace the failed hard drive(s) with new hard drive(s) that are 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 10 Volume

Note: When a RAID 10 volume is in the failed state, unless it is in the failed state because two adjacent member hard drives have been disconnected, the RAID 10 volume cannot be recovered and any data on the RAID 10 volume is lost.

Two Missing Members

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

Three or Four Missing Members

Note: When a RAID 10 volume is in the failed state because three or four member hard drives have been disconnected, the RAID 10 volume cannot be recovered and any data on the RAID 10 volume is lost. This procedure deletes the failed RAID 10 volume.

1. Make sure the system is powered off.
2. Reconnect the missing hard drives.
3. Power on the system. During the system startup, the Intel Matrix Storage Manager option ROM user interface will display the RAID 10 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 10 volume.
7. Press the Delete key to delete the volume.
8. Press Y to confirm the deletion.
9. Create a new RAID 10 volume.
10. You will then need to reinstall the operating system on the new volume.

Failed Members

Note: When a RAID 10 volume is in the failed state because the member hard drives have failed, the RAID 10 volume cannot be recovered and any data on the RAID 10 volume is lost. This procedure deletes the failed RAID 10 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 10 volume status as "Failed," prompting you to press Ctrl-I to enter the user interface.

6. In the "Delete Volume Menu," use the up and down arrow keys to select the failed RAID 10 volume.
7. Press the Delete key to delete the volume.
8. Press Y to confirm the deletion.
9. Create a new RAID 10 volume.
10. You will then need to reinstall the operating system on the new volume.
