 ## Troubleshooting
 
 * You can set persistence mode using `nvidia-smi` so the output of the command is faster when you need to query cards. To set persistence mode, execute `nvidia-smi -pm 1`. Note that if the VM is restarted, the mode setting goes away. You can always script the mode setting to execute upon startup.
-* If you updated the NVIDIA CUDA drivers to the latest version and find RDMA connectivcity is no longer working, [reinstall the RDMA drivers](https://docs.microsoft.com/azure/virtual-machines/linux/n-series-driver-setup#rdma-network-connectivity) to reistablish that connectivity.
