I am getting following result. So, is it ver.2 or ver.3? Please clarify.

rpcinfo -p localhost | grep -i nfs

100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs

Thanks.

The both version 2 and version 3 are supported.
Now it depends which version will you prefer when mounting:

#mount -o vers=n: The version of the NFS protocol is used

Hi Anand,

The rpcinfo command (as previously posted) will show you the versions of NFS supported by a specific server. HP-UX 11.11 supports NFS v2 and v3. At 11.31 we introduced support for NFS v4, however it is disabled by default. If you wish to enable NFS v4 server support you can modify the /etc/default/nfs file as follows:

NFS_SERVER_VERSMAX=4

After making this change you will need to restart the NFS server daemons to activate NFS v4 support:

/sbin/init.d/nfs.server stop
/sbin/init.d/nfs.server start

Then rpcinfo should report NFS v2/3/4 on the 11.31 server.

Regards,

Dave
