Please post the contents of your /etc/exports file.
If I understand correct you are trying to export a directory that is actualy an nfs mount which was exported by another server. Why? It is already exported that other server.

Main server where it is mounted is very critical one so we do not want to mount it directly. & 2nd thing is that the disk which is
on this critical server was on this Vishal server only due to os curruption issue we attached this disk to the critical server vinayak

Re: Nfs mount on nfs mounted disk from somewhere....nested nfs???

Above issue is easily reproducible as below:
1]do nfs mount disk from server called "A"
2]let that mount nfs as "MOUNTA" directory on machine /server "B"
3]then export that as nfs mount to have access to others i.e to 3rd party server/machines.

I am trying this scenario only due to which I am getting below Error:

Re: Nfs mount on nfs mounted disk from somewhere....nested nfs???

Are you trying to re-export an nfs mounted filesystem? That is not allowed by hp-ux for securtiy reasons.

How is this going to make it more reliable?
The main server isn't going to have any problem with NFS clients, other than being slowed down.

This is telling you that you can't do this. You have to mount the filesystem from the original server. There is no daisy chaining of NFS.

I seriously doubt the main reason is security, perhaps data integrity or the design of NFS.
