Upgrade NVIDIA Driver
=====================
If the user wants to update the newer NVIDIA driver on the system, need to :doc:`create New CUDA software reposity </advanced/gpu/nvidia/repo/index>` . Assume the newer driver is in the ``/install/cuda-7.5/ppc64le/nvidia_new`` for the following processes.
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 upgrade NVIDIA driver on the compute node: ::
updatenode <noderange> -S
#. Reboot compute node: ::
rpower <noderange> off
rpower <noderange> on
#. Verify the newer driver level on the compute node: ::
nvidia-smi | grep Driver
Diskless
--------
For update new NVIDIA driver on the diskless compute node, the easy and simple way is re-generate the osimage with New NIVIDIA driver reposity and re-provision the node with this osimage because node needs to be reboot in order for NIVIDIA driver to load. Please follow :doc:`this doc </advanced/gpu/nvidia/osimage/index>` to create osimage definitions and deploy CUDA nodes.
