Try editing /etc/mnttab and remove the nfs entry from the client.

mnttab(4) is a read only file that is updated directly by the kernel and says:

It should never be manually edited,

Did you mean fstab(4)?

We can edit /etc/mnttab in HP-UX 11iv1 and V2 but not in V3.

By removing an stale entry from mnttab file we can get rid of them

Hello expert,

i was unable to edit the /etc/mnttab file ......

However i checked the file there is an entry in "ODBICBS :/var/opt/ignite/clients /var/opt/ignite/recovery/client_mnt nfs rsize=32768,wsize=32768,NFSv3,dev=4000008 0 0 1388120986"

Hello Dennis sir,

What should i suppose to do now to resolve this issue.

Have you tried umount -f?

Dose it unmount all the shared file system ...or is there any thing specifically needs to be done.

Request you to please suggest me steps for the same.

Thanks & have a great day ahead,

With regards,
Vishal

You need to learn how to use the manpages. That and my hint about using umount -f should have given you enough info.

mount_nfs(1M) says:

/sbin/fs/nfs/umount [-df] {resource | mount_point}

umount -f /var/opt/ignite/recovery/client_mnt
