Re: How to unmount the NFS. Please help.
To unmount NFS imported you can use:
umount -h xyz.com -a
This will unmount all mount imported from the host.

Re: How to unmount the NFS. Please help.

I tried to issue:
# showmount -a
showmount: puyuh: RPC: Program not registered

# umount -h xyz.com -a

shall i use like this:
# umount -h kedidi -a

Re: How to unmount the NFS. Please help.
hostname you are using into command should be same as mentioned into /etc/mnttab. You can verify this name by running bdf command where it can be seen as xyz.com:/filesys.

Re: How to unmount the NFS. Please help.
did you try to modify the /etc/hosts or DNS entry so that the server resolves to the new address?
(may also have to modify your /etc/exports)
this can work.

Re: How to unmount the NFS. Please help.
the problem is to umount a not-responding file-system!
With the right os (as said above) you can use the force-option, else you have to reconnect to the nfs-server first or do a reboot.
If it's only the ip-address, then you have to change this address for server B in the /etc/hosts of server A.
Then the reconnect should work.
To unmount a directory check your /etc/fstab, there, for example, is:
'server:/bitmaps /bitmaps nfs'
Then your command is 'umount /bitmaps'.
Else, before reboot(!), you should change the /etc/fstab and comment out all directories with are mounted from server B.

Re: How to unmount the NFS. Please help.
Thanks a lot for your close guidance. I was able to NFS server B not responding.
I commented the respective entry in the /etc/fstab and /etc/mnntab from the NFS client. When I issue bdf in the NFS client, the NFS server B not responding was disappear. Thanks a lot. :)
