My T5820 has the FlexiBay populated with 2 x NVME SSDs, one if the System Disk.

All was working fine until I upgraded the BIOS to 1.9.0 and now I get 4 amber followed by 6 white flashes on the front power LED.

This indicates 'RAID Volume degraded'.

On investigation in the BIOS and Device Configuration I see that the Intel VMD VROC (pass thru) is saying that none of the disks are RAID disks.

This has not changed since I upgraded the BIOS.

Any ideas what should I do to sort the cause of the error ?

Thanks,

David
