fuser -ck from the nsf client , followed by a umount on nfs server.

If you're using HP-UX 11i v2 or v3 you can also try using the -f (force) option:

# umount -f

Re: NFS unmounting problem

fuser -cu and fuser -ck should do the trick as the folks have mentioned (similar concept on a local server) but also make sure that the mount point you are trying to unmount is not the mount point of another file system.
Read, read and read... Then read again until you read "between the lines".....

You need to eject if any DVD/CD present in the drive before unmounting the mountpoint

No, it's just the reverse: in order to eject the CD/DVD, first you need to umount it.
