P920 RAID 10 Volume failed

2020-06-23, 23:10 PM

Two months ago, I added a Quad M.2 Adapter with 4 Seagate FireCuda 510 M.2 2TB SSDs and an Intel VROC Premium key.  I created a RAID 10 volume that is 3539.72GB containing 3 virtual disks of approximately equal size.  The RAID volume is non-bootable.  I cloned my operating system onto a fifth FireCuda that uses a M.2 slot on the planar board.  So, Windows 10 and my software is on the fifth M.2 as the C: drive and my data is on the RAID volume in virtual disks D:, E:, and F:.  Everything has been running very well for the past 60-plus days.  This afternoon, the RAID volume suddenly failed.  I rebooted the system (since I have a working OS) and examined the event log (Administrative Events).  Four files are attached.  The first two capture the initial hardware failure (.EVTX and .TXT formats).  The second pair of files capture events after a hard boot later this afternoon (also .EVTX and .TXT).

 

I restarted in setup mode and examined "Intel VROC Managed VMD" (please see the three attached photographs).  My only option is delete, but although I have a backup of the missing virtual disks, I want to hold off from that step until I hear some advice.

 

Is there any software in the Lenovo (or Intel) toolset that will allow me to diagnostic the reason for the failure and perhaps get that M.2 hardware back on-line?  Is the Quad M.2 Adapter the cause?  I am clueless.

 

Diagnostic documentation is slim to none.  I would like to determine exactly what failed.  Please help.

 

Thank you,  -Ja Fehr

 

P.S.  The "Attach File" button does not seem to be working.  Please advise if you cannot see my attachments and I will re-send them one at a time.  Thank you.

Solved! See the solution

Correction!

 

When I wrote "virtual disks" in my first post today, I meant to write "partitions".  My internal (personal) cut/paste buffer is also corrupted. :)

One thing you could try is launching the Intel RST utility from within Windows.  This should allow you to see if a single drive has gone done or what part of the RAID array failed.

Hi,

 

Thank you for the advice.  I ran Intel Virual RAID on CPU app (version 6.2.0.1238) and observed failed NVMe's at ports 2 and 3.  Since, according to the event log, they failed at the same instant, I marked them as normal and initiated a rebuild.  By the way, disk caching was previously disabled.  The rebuild took about 45-50 minutes with no events logged.  I am going to reboot and run a CHKDSK on each partition, but the prognosis is good.

 

Maybe my quad board was struck by a stray cosmic ray.  I cannot find a root cause for the hardware failure.

 

Thank you again, very much,  -Ja

With my P920 and Intel VROC I have a similar experience. I have used both M2 slots on the planar for an Intel VROC Raid1 volume. And I have installed 4 NVMe drives in a Lenovo Quad M2 adapter for an Intel VROC Raid10 volume.

My Raid1 volume which used both M2 slots on the planar and which is the C: drive of my Windows 10 installation failed more than 10 times during the last months. Similar like your Raid10 volume failed.

There never was a real single failure from the HW side; after I rebooted the P920 (from a SSD mounted at the front bay) I could set both NVMe SSDs to normal, then the Raid1 volume was rebuild and all was OK then.

 

What I observed in BIOS was that when the Lenovo Quad M2 adapter and NVMe SSDs in the M2 slots on the planar are installed the BIOS sees a device in slot 4 which in reality is not there.

I don't know if this has anything to do with the Intel VROC failures I got, but it is certainly an anomaly.

I would be grateful if you could check in BIOS on your P920 the status of slot 4 (and slot 2).

I assume you don't have any adapter in slot 2 and slot 4.

If you see a phantom device in slot 4 (or slot 2) you have the same anomaly like I see on my P920 and I believe this should be fixed by Lenovo.

 

 

Slot 4 status looks like this on my P920 with the phantom device:

 

And this is how it should be:

 

 

Hopefully you will never get a Intel VROC failure again.

I have currently migrated my Windows 10 drive from both M2 slots on the planar to a Raid10 volume consisting of four NVMe drives in the Lenovo Quad M2 adapter.

Seeing that your Raid10 volume on the Lenovo Quad M2 adapter failed similar like my Raid1 volume failed in the past I don't have much hope that I have solved my Intel VROC problem.

 

Either Intel VROC is basically unstable or something is wrong with the P920.

 

Thanks for your help.
