Why Is the T4 GPU Display Abnormal?

Symptom

An ECS, for example, of the PI2 or G6 flavor, is using NVIDIA Tesla T4 GPUs. However, when you run the nvidia-smi command to check the GPU usage, the following information is displayed: 
No devices were found

Possible Causes

The NVIDIA Tesla T4 GPU is a new version of the NVIDIA GPU. By default, the GSP firmware is enabled and used. As a result, the GPU cannot be identified.

Method 1

The following settings will become invalid after the ECS is restarted.

  1. Remove the NVIDIA kernel module.

    rmmod nvidia_drm

    rmmod nvidia_modeset

    rmmod nvidia

  2. Disable GSP firmware and load the NVIDIA kernel module.

    modprobe nvidia NVreg_EnableGpuFirmware=0

    modprobe nvidia_drm

    modprobe nvidia_modeset

  3. If the fault persists, contact customer service.

Method 2

  1. Run the following command to open the /etc/modprobe.d/nvidia.conf file:

    vim /etc/modprobe.d/nvidia.conf

    Press i to enter the editing mode.

  2. Add the following information to /etc/modprobe.d/nvidia.conf: 
    options nvidia NVreg_EnableGpuFirmware=0

    Press Esc and enter :wq! to save the modification and exit.

  3. Run the following command to restart the ECS:

    reboot

  4. If the fault persists, contact customer service.
