I don't know about VMS specifically, but it is usual for NFS to
allow for hard mount or soft mount.  Hard mount never times out,
just as an access for a local disk never times out.

There are some complications if you do file locking, but normally
the server comes back and the client continues on like nothing
changed.  If you do change something on the server, like rename
the disk, move it around, or otherwise, you should get "Stale
File Handle" or some similar message.
