nvidia-smi returns failed result on Cisco b200-m4

I have b200-m4 server with m6 card installed. However after installing the vib using the Grid quick startup guide, the nvidia-smi returns error. Any information regarding why? I see this Cisco server is certified with grid:

[root@localhost:~] nvidia-smi
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

You probably need to switch from “3D controller” to “VGA Controller” mode - see http://nvidia.custhelp.com/app/answers/detail/a_id/4164/~/running-the-gpumodeswitch-tool-on-grid-m60%2Fm6-cards-on-vmware-esxi-returns-an + study package “NVIDIA-gpumodeswitch-2016-04.zip” + “GRID gpumodeswitch User Guide.pdf” … and blogs like https://virtuallyvisual.wordpress.com/2016/04/19/nvidia-m60-m6-problems-check-your-card-in-graphics-mode/ and https://www.youtube.com/watch?v=VAQhiNNFXxQ

Thanks, I followed it, however getting this error now. I also see this same error from net ssh connection but also from hypervisor’s its own console:

[root@localhost:~] gpumodeswitch --gpumode graphics

Update GPU Mode of all adapters to “graphics”?
Press ‘y’ to confirm or ‘n’ to choose adapters or any other key to abort:

Updating GPU Mode of all eligible adapters to "graphics"

ERROR: Read card info failed by using character device based.

  1. You can try to switch mode over console (CIMC) with included linux bootable gpumodeswitch.iso image (selected mode is persistent on card).
  2. You can try detect errors with "gpumodeswitch --listgpumodes" and/or output log "more /tmp/listgpumodes.txt" as described in pdf. You can try "esxcli hardware pci list" or "esxcfg-info -a" or search log for relevant errors "/var/log/vmkernel.log" …
  3. You can try contact/call NVidia support if you paid for Support Updates and Maintenance agreement (SUMS).

i did and it is now in what appears to be in graphics mode. But nvidia-smi still returning the same crap. I am out of here.

You can try more blogs (or directly Cisco for validated setup) - https://virtuallyvisual.wordpress.com/2016/06/20/new-cisco-validated-design-featuring-ucs-b200-m4-with-nvidia-grid-m6-vgpu-available-now/ - for example - ESXi 6.0 Update 1, upgrade your Cisco UCS system to a version of Cisco UCS Manager that supports this card, BIOS tweaking (card must be mapped under 4G address space for ESXi) …

As an M6 user you should be entitled to support via your licenses. Please do raise a support case with the organisation you bought the licenses and support from e.g. Cisco or NVIDIA as appropriate.
