Failed volumes
This section explains how to resolve the most common problems that may occur while using the application. If the user has any questions regarding installing, using or maintaining this product, the user can also visit Intel's online support site which provides the user with self-help resources and electronic problem submission.
RAID 0
A RAID 0 volume is reported as failed when one of its members is disconnected or has failed. In both cases, the volume and its data are no longer accessible.
Cause 1
Missing array disk.
Solution 1
Follow this procedure to recover data:
- Power off the user’s computer and reconnect the missing disk.
Turn on the user’s computer. During the system startup, the volume status will display as 'Normal' in the Intel Rapid Storage Technology enterprise option ROM user interface.
Once the operating system is running, open Intel Rapid Storage Technology enterprise from the Start menu or click the Intel Rapid Storage Technology enterprise notification area icon.
Under 'Status', verify that the volume and disks status display as 'Normal'. The user can also review this information under 'Manage'.
Cause 2
Failed array disk.
Solution 2
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, and then attempt a data recovery. If the read/write data access consistently fails, the disk will likely return to a failed state immediately. See Disk events for instructions on resetting a disk to normal.
This procedure deletes the failed volume:
Power off the user’s computer and replace the failed NVMe or SATA disk with a new one that is of equal or greater capacity.
Turn on the user’s computer. During the system startup, the volume status will display as 'Failed' in the Intel Rapid Storage Technology enterprise option ROM user interface.
Press Ctrl-I to access the main menu of the option ROM user interface.
Select Delete RAID Volume from the main menu.
From the Delete Volume menu, select the failed RAID volume, using the up and down arrow keys.
Press the 'Delete' key to delete the volume, then 'Y' to confirm.
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.
RAID 5
A RAID 5 volume is reported as failed when two or more of its members have failed.
Cause
Two or more array disks failed.
Solution
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, and then attempt a data recovery. If the read/write data access consistently fails, the disk will likely return to a failed state immediately. See Disk events for instructions on resetting a disk to normal.
This procedure deletes the failed volume:
Power off the user’s computer and replace the failed NVMe or SATA disks with new ones that are of equal or greater capacity.
Turn on the user’s computer. During the system startup, the volume status will display as 'Failed' in the Intel Rapid Storage Technology enterprise UEFI HII.
Go into the BIOS setup and go to the Intel VROC UEFI HII.
Select Delete RAID Volume from the main menu.
From the Delete Volume menu, select the failed RAID volume, using the up and down arrow keys.
Press the 'Delete' key to delete the volume, then 'Y' to confirm.
Create a new RAID 5 volume using the new disks. If the failed disk was part of the system volume, the user will also need to reinstall the operating system.
RAID 10
A RAID 10 volume is reported as failed when two adjacent members are disconnected or have failed, or when three or four of its members are disconnected or have failed.
Cause 1
Two adjacent array disks missing (visual inspection).
Solution 1
Power off the user’s computer and reconnect the missing disks.
The rebuild operation will start automatically. The user can follow the progress by hovering over the notification area icon or by reviewing the volume status under 'Status' or 'Manage'.
Cause 2
Three or four array disks missing.
Solution 2
In most cases, the volume cannot be recovered and any data on the volume is lost.
To delete the failed volume:
Power off the user’s computer and reconnect the missing disks.
Turn on the user’s computer. During the system startup, the volume status will display as 'Failed' in the Intel Rapid Storage Technology enterprise UEFI HII.
Go into the BIOS setup and go to the Intel VROC UEFI HII.
Select Delete RAID Volume from the main menu.
From the Delete Volume menu, select the failed RAID volume, using the up and down arrow keys.
Press the 'Delete' key to delete the volume, then 'Y' to confirm.
Create a new RAID 10 volume using the new disks.
The user will then need to reinstall the operating system on the new volume.
Cause 3
Two or more array disks failed.

Create a new RAID 10 volume using the new disks.
The user will then need to reinstall the operating system on the new volume.
