Hi,

Please see the recommendations below:

Update BIOS rom to latest - 2.22_11-13-2019(18 Nov 2019) (Please refer the rivision history for fixes), 

https://support.hpe.com/hpsc/swd/public/detail?swItemId=MTX_55c6312f9c634f5782048519dd#tab-history

Recommended to change the workload profile to HPC-high performance computing or Virtulization Max performance. and check the status.

And for 

"PCI Bus Uncorrectable PCI Express Error Detected. Slot 255 (Segment 0x0, Bus 0x5D, Device 0x1, Function 0x0)"

"Bus 0x5D, Device 0x1, Function 0x0"==> Need to decode and check to which device its pointing.

Please try to to check PCI device properties or nvme drive properties incase its matching .

If identified, try to update the the firmware.

Regards,

Sudhir

Thanks   sudhirsingh , 

After my last post I did upgrade the system to  Bios Version: 2.16_09-12-2019 (26 Sep 2019) , which was recommended,  I will keep monitoring the server, in case of any panic , will do upgrade to newest FW.
