Intel Optane Memory and Storage Manager shows RAID5 member as "Failed" but drive is fine

[helzayat]

I have 4x6TB RAID5 (18TB) array. Intel Optane Memory and Storage Manager shows the array as degraded and one of the drives as failed.
Hard Disk Sentinel shows that drive's health as 100%, it passes the short test and there are no SMART problems. Intel SSU says the array is fine: Error Code Device is working properly
(report attached)
I am able to read and write from the volume with maybe a little speed loss.

In BIOS the drive is marked as failed and I have the option to reset it to non-RAID

In the app, the only option is "Delete volume"
I believe the drive is fine and the problem is with the RAID setup, how can I restore the volume without having to copy 14TB of datat?

Hi helzayat,

Thank you for reaching out regarding this matter. To better diagnose the issue, kindly provide the following:

1. Are there any recent changes made before the issue occurred?
2. Has the drive been physically moved or reconnected to a different port or controller?
3. Are all firmware and Intel RST drivers up to date?
4. Is the Intel Optane Memory and Storage Manager software version current?
5. What troubleshooting steps have you tried to resolve the issue?
6. Can you provide sample images of the BIOS interface versus the app regarding the drive status?
7. What is the make and model of your Optane Memory?

Thank you, and I look forward to your response.

Best Regards,

1 & 2: no
3 & 4: yes
The drive that RST decided had failed was connected to the SATA port that shares bandwidth with an M2 port to which an NVMe SSD was connected. Possibly that caused the drive to appear faulty. I set the drive back to non-RAID, moved the SSD to another M2 slot, re-added the drive to the RAID array and rebuilt the RAID-5. This seems to have solved the problem.

I have no Optane memory in this system.
