Workaround If the issue is due to NFS/UDP and firewall, check if the client mounts using UDP (this is usually the default) and there is a firewall in the path. If a firewall exists, add an appropriate exception to the firewall.

If the issue is due to permissions:

Verify the path you provided is correct.

Check that you are trying to mount as root.

Check that the system's IP address, IP range, domain name or netgroup is in the exports list.

If the server not responding due to a port mapper failure:

Check the PowerVault NX3500 status.

Check the network connection by trying to NFS mount from some other system.

Verify if other users experience the same problem.

If the server is not responding due to the program not registered, check if the port mapper on your client is up.

If the issue is due to access denied:

Get a list of the server exported file systems using the command: showmount -e <NX3500 hostname>

Check the system name or netgroup name is not in the user list for the file system.

Check the file systems related to the NFS through the PowerVault NX3500 user interface.

If the issue is due to the directory, check the spelling in your command and try to run the mount command on both directories.
