Update NVIDIA Driver

If the user wants to update the newer NVIDIA driver on the system, follow the Create CUDA software repository </advanced/gpu/nvidia/repo/index> document to create another repository for the new driver.

The following example assumes the new driver is in /install/cuda-9.2/ppc64le/nvidia_new.

Diskful

  1. Change pkgdir for the cuda image: :

    chdef -t osimage -o rhels7.5-ppc64le-install-cudafull \
  pkgdir=/install/cuda-9.2/ppc64le/nvidia_new,/install/cuda-9.2/ppc64le/cuda-deps

  2. Use xdsh command to remove all the NVIDIA rpms: :

    xdsh <noderange> "yum remove *nvidia* -y"

  3. Run updatenode command to update NVIDIA driver on the compute node: :

    updatenode <noderange> -S

  4. Reboot compute node: :

    rpower <noderange> off
rpower <noderange> on

  5. Verify the newer driver level: :

    nvidia-smi | grep Driver

Diskless

To update a new NVIDIA driver on diskless compute nodes, re-generate the osimage pointing to the new NVIDIA driver repository and reboot the node to load the diskless image.

Refer to Create osimage definitions </advanced/gpu/nvidia/osimage/index> for specific instructions.
