VMS Help TCPIP Services, NFS, File System  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The NFS file system on OpenVMS includes a hierarchy of devices,
    directories, and files stored on a File-11 On-Disk Structure
    (ODS-2) formatted disk.

    You can set up and export two different kinds of file systems:

    o  Traditional OpenVMS file system

    o  UNIX style (container) file system built on top of an OpenVMS
       file system.

    To set up and maintain these file systems, you issue management
    commands.
