Intel® Virtual RAID on CPU (Intel® VROC) Troubleshooting Tips for Failed Volumes in Windows* Environments

1. Power off the system and reconnect the missing disk.
2. Turn on the system. During the system startup, the volume status will display as Normal in the Intel® VROC UEFI HII.
3. Once the operating system is running, open the Intel® VROC GUI from the Start menu or click the Intel® VROC notification area icon.
4. Under the  Status header, verify that the volume and disks status display as Normal. The user can also review this information under the Manage header.

In most cases, the volume cannot be recovered and any data on the volume is lost. However, before deleting the volume, you can try resetting the disk to normal, and then attempt a data recovery. If the read/write data access consistently fails, the disk will likely return to a failed state immediately. Refer to Intel® Virtual RAID on CPU (Intel® VROC) Troubleshooting Tips for Disk Events in Windows* Environments for instructions on resetting a disk to normal.

This procedure deletes the failed volume:

1. Power off the system and replace the failed NVMe* or SATA disk with a new one that is of equal or greater capacity.
2. Turn on the system. During the system startup, the volume status will display as Failed.
3. Go into the BIOS Setup and navigate to the Intel® VROC UEFI HII menu. This menu is displayed as Intel® Virtual RAID on CPU for NVMe* devices, and Intel® VROC SATA/sSATA Controller for SATA and sSATA devices respectively.
4. Select the Delete RAID Volume option from the main menu.
5. From the Delete Volume menu, select the failed RAID volume, using the up and down arrow keys.
6. Press the Delete key to delete the volume, then press the Y key to confirm.
7. Create a new RAID 0 volume using the new disk. If the failed disk was part of the system volume, the user will also need to reinstall the operating system.

5. Select Reset to Normal.
6. Confirm resetting the volume to normal.
7. Exit the HII and re-enter the HII. Confirm that the previously failed RAID 0 volume now shows Normal status.

In most cases, the volume cannot be recovered and any data on the volume is lost. However, before deleting the volume, the user can try resetting the disk to normal as if the array disk was only missing (follow the steps from the section above), and then attempt a data recovery. If the read/write data access consistently fails, the disk will likely return to a failed state immediately.

This procedure deletes the failed volume. Follow these steps if resetting the volume to normal didn't work:

1. Power off the system and replace the failed NVMe* or SATA disk with a new one that is of equal or greater capacity.
2. Turn on the system.
3. Go into the BIOS Setup and navigate to the Intel® VROC UEFI HII menu. This menu is displayed as Intel® Virtual RAID on CPU for NVMe* devices, and Intel® VROC SATA/sSATA Controller for SATA and sSATA devices respectively.
4. Select the failed RAID 0 volume inside the appropriate HII menu.

If the read/write data access consistently fails, the disks will likely return to a failed state immediately.

This procedure resets the array to normal:

1. Power off the system and reconnect the missing disks.
2. Turn on the system.
3. Go into the BIOS Setup and navigate to the Intel® VROC UEFI HII menu. This menu is displayed as Intel® Virtual RAID on CPU for NVMe* devices, and Intel® VROC SATA/sSATA Controller for SATA and sSATA devices respectively.
4. Select the failed RAID 5 volume inside the appropriate HII menu.
5. Select the Reset to Normal option.
6. Confirm resetting the volume to normal.
7. Exit the HII and re-enter the HII. Confirm that the previously failed RAID 5 volume now shows Normal status.

This procedure deletes the failed volume if resetting it to normal didn't work:

1. Power off the system and replace the failed NVMe* or SATA disks with new ones that are of equal or greater capacity.
2. Turn on the system.
3. Go into the BIOS Setup and navigate to the Intel® VROC UEFI HII menu. This menu is displayed as Intel® Virtual RAID on CPU for NVMe* devices, and Intel® VROC SATA/sSATA Controller for SATA and sSATA devices respectively.
4. Select the failed RAID 5 volume inside the appropriate HII menu.
5. Select the Delete RAID Volume option from the menu and confirm deleting the volume when asked.
6. Create a new RAID 5 volume using the new disks. If the failed disks were part of the system volume, the user will also need to reinstall the operating system.

In most cases, the volume can be recovered successfully and any data on the volume will remain intact. However, the user must keep in mind the state of the array between becoming degraded (losing 1 disk only) and becoming failed (losing the second and all subsequent disks).

If the array has not been written to after it originally became degraded, the user can follow the procedure outlined below for resetting the array to normal to recover the array and the data:

1. Power off the system and reconnect the missing disks.
2. Turn on the system.
3. Go into the BIOS Setup and navigate to the Intel® VROC UEFI HII menu. This menu is displayed as Intel® Virtual RAID on CPU for NVMe* devices, and Intel® VROC SATA/sSATA Controller for SATA and sSATA devices respectively.
4. Select the failed RAID 5 volume inside the appropriate HII menu.
5. Select the Reset to Normal option.
6. Confirm resetting the volume to normal.
7. Exit the HII and re-enter the HII. Confirm that the previously failed RAID 5 volume now shows Normal status.

If the array has been written to after the first disk became missing and before the second and subsequent disks became missing, but all disks still work (and their metadata remains unchanged from the point of removal), the user can follow the procedure below to restore the RAID 5 volume to normal without losing data:

1. Power off the system and replace any missing disks in their original location if possible.
2. Turn on the system.
3. Go into the BIOS Setup and navigate to the Intel® VROC UEFI HII menu. This menu is displayed as Intel® Virtual RAID on CPU for NVMe* devices, and Intel® VROC SATA/sSATA Controller for SATA and sSATA devices respectively.
4. Select the failed RAID 5 volume inside the appropriate HII menu.
5. Select the Reset to Degraded option and confirm the selection when asked. The volume status will change to Degraded. The user will be presented with a menu to select the disks they wish to include in the degraded array. The disks to include in this array are the disks that were included in the originally degraded array. The user should select every disk from the original normal array besides the first disk that was removed from the system. The system will detect that the first missing disk is now present and will begin rebuilding the RAID 5 volume to that disk from the metadata on the disks the user chose to include in the degraded array when it was reset to degraded. The array status will change to Rebuilding. After the rebuild process completes, the data should be recovered. The array status will change to Normal.

If up to one disk has failed, and any number of other disks were subsequently removed from the system (and the working disks’ metadata remains unchanged from the point of removal) the user can follow the below procedure to restore the RAID 5 volume to normal without losing data:

1. Power off the system and replace any missing disks in their original location if possible. Replace the failed disk with a new disk that is of equal or greater capacity as the failed disk.
2. Turn on the system.
3. Go into the BIOS Setup and navigate to the Intel® VROC UEFI HII menu. This menu is displayed as Intel® Virtual RAID on CPU for NVMe* devices, and Intel® VROC SATA/sSATA Controller for SATA and sSATA devices respectively.
4. Select the failed RAID 5 volume inside the appropriate HII menu.
5. Select the Reset to Degraded option and confirm the selection when asked. The volume status will change to Degraded. The user will be presented with a menu to select the disks they wish to include in the degraded volume. The disks to include in this volume are the disks that were included in the originally degraded volume. The user should select every working disk from the original volume.
6. Exit the HII and re-enter the HII. There should be a new option called Rebuild under the now-degraded RAID 5 volume.
7. Select the Rebuild option. A menu will be shown containing all of the non-RAID disks on the system. Select the new disk and confirm the rebuild process when asked. The RAID 5 volume will begin rebuilding the data on the working member disks to the newly inserted disk. The volume status will change to Rebuilding. After the rebuild process completes, the data should be recovered. The volume status will change to Normal.

In most cases, the volume can be recovered successfully and any data on the volume will remain intact. However, the user must keep in mind the state of the array between becoming degraded (losing 1 disk only) and becoming failed (losing the second disk). 

If the array has not been written to after it originally became degraded, the user can follow the procedure outlined below for resetting the array to normal to recover the array and the data:

1. Power off the system and reconnect the missing disks.
2. Turn on the system.
3. Go into the BIOS Setup and navigate to the Intel® VROC UEFI HII menu. This menu is displayed as Intel® Virtual RAID on CPU for NVMe* devices, and Intel® VROC SATA/sSATA Controller for SATA and sSATA devices respectively.
4. Select the failed RAID 10 volume inside the appropriate HII menu.
5. Select the Reset to Normal option.
6. Confirm resetting the volume to normal.
7. Exit the HII and re-enter the HII. Confirm that the previously failed RAID 10 volume now shows Normal status.

If the array has been written to after the first disk became missing and before the second disk became missing, but all disks still work (and their metadata remains unchanged from the point of removal), the user can follow the procedure below to restore the RAID 10 volume to normal without losing data:

1. Power off the system and replace any missing disks in their original location if possible.
2. Turn on the system.
3. Go into the BIOS Setup and navigate to the Intel® VROC UEFI HII menu. This menu is displayed as Intel® Virtual RAID on CPU for NVMe* devices, and Intel® VROC SATA/sSATA Controller for SATA and sSATA devices respectively.
4. Select the failed RAID 10 volume inside the appropriate HII menu.
5. Select the Reset to Degraded option. The user will be presented with a menu to select the disks they wish to include in the degraded array. The disks to include in this array are the disks that were included in the originally degraded array. The user should select every disk from the original normal array besides the first disk that was removed from the system. The system will detect that the first missing disk is now present and will begin rebuilding the RAID 10 volume to that disk from the metadata on the disks the user chose to include in the degraded array when it was reset to degraded. The array status will change to Rebuilding. After the rebuild process completes, the data should be recovered. The array status will change to Normal.

In most cases, the volume can be recovered successfully and any data on the volume will remain intact. However, the user must keep in mind the state of the array between becoming degraded (losing 1 disk only) and becoming failed (losing the second disk and any subsequent third or fourth disks). Refer to the above instructions for recovering a RAID 10 volume with two missing disks. The same process applies for three or four missing disks.

In most cases, the volume cannot be recovered and any data on the volume is lost. However, before deleting the volume, the user can try resetting the disks to normal as if the array disks were only missing, and then attempt a data recovery. If the read/write data access consistently fails, the disks will likely return to a failed state immediately.

This procedure is to reset the array to normal:

1. Power off the system and reconnect the missing disks.
2. Turn on the system.
3. Go into the BIOS Setup and navigate to the Intel® VROC UEFI HII menu. This menu is displayed as Intel® Virtual RAID on CPU for NVMe* devices, and Intel® VROC SATA/sSATA Controller for SATA and sSATA devices respectively.
4. Select the failed RAID 10 volume inside the appropriate HII menu.
5. Select the  Reset to Normal option.
6. Confirm resetting the volume to normal.
7. Exit the HII and re-enter the HII. Confirm that the previously failed RAID 10 volume now shows Normal status.

This procedure deletes the failed volume if resetting it to normal didn't work:

1. Power off the system and replace the failed NVMe* or SATA disks with new ones that are of equal or greater capacity.
2. Turn on the system.
3. Go into the BIOS Setup and navigate to the Intel® VROC UEFI HII menu. This menu is displayed as Intel® Virtual RAID on CPU for NVMe* devices, and Intel® VROC SATA/sSATA Controller for SATA and sSATA devices respectively.
4. Select the failed RAID 10 volume inside the appropriate HII menu.
5. Select the Delete RAID Volume option from the menu and confirm deleting the volume when asked.
6. Create a new RAID 10 volume using the new disks. If the failed disks were part of the system volume, the user will also need to reinstall the operating system.
