Symptoms:
1. Ensure that ECC memory is disabled on all GPUs if you are using NVIDIA vGPU.
• To check whether the ECC is enabled or not, run the command:
nvidia-smi -q
2. If ECC is enabled, then disable ECC.
a. Put your host in maintenance mode.
b. Start an SSH session to your ESX host and apply the following commands:
1. /etc/init.d/xorg stop
2. nv-hostengine -t
3. nv-hostengine -d
4. /etc/init.d/xorg start
5. nvidia-smi -e 0
6. reboot
If in the customer vSphere environment, multiple ESXi hosts have graphics cards and one has has ECC disabled, vMotion with vGPUs will fail.
