Hi NV Team,
Please give me advice to resolve the issue.
Issue:
Suddenly our server did not recognized one A100 cards of two ones by nvidia-smi after restarting server.
Note:
lspic command showed the two cards like below.
nvidia@a100-server-b:~$ lspci | grep NVIDIA
24:00.0 3D controller: NVIDIA Corporation Device 20f1 (rev a1)
e1:00.0 3D controller: NVIDIA Corporation Device 20f1 (rev a1)
