Update NVIDIA Driver
=====================
If the user wants to update the newer NVIDIA driver on the system, follow the :doc:`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-7.5/ppc64le/nvidia_new``.
Diskful
-------
#. Change pkgdir for the cuda image: ::
chdef -t osimage -o rhels7.2-ppc64le-install-cudafull \
pkgdir=/install/cuda-7.5/ppc64le/nvidia_new,/install/cuda-7.5/ppc64le/cuda-deps
#. Use xdsh command to remove all the NVIDIA rpms: ::
xdsh <noderange> "yum remove *nvidia* -y"
#. Run updatenode command to update NVIDIA driver on the compute node: ::
updatenode <noderange> -S
#. Reboot compute node: ::
rpower <noderange> off
rpower <noderange> on
#. 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 :doc:`Create osimage definitions </advanced/gpu/nvidia/osimage/index>` for specific instructions.
