A stale NFS handle usually occurs when a networked drive has been unexpectedly been disconnected, by power down, reboot, network failure, etc, etc.
There should be a definition of the network mounts in /etc/vfstab on the client. Compare the entries in this file with the output of
# df -k (also on the client)
to see which mounts are not there and manually mount them.
# mount remote:/c0t0d0s0 /mnt
is a vague example.
If you are confident you could use
# mount all
which will mount all the definitions in the /etc/vfstab
Hope this helps Ian
