VMS Help V73 Features, System Management Features, OpenVMS Cluster Systems, Floppy Disks Served  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Until this release, MSCP was limited to serving disks. Beginning
    with OpenVMS Version 7.3, serving floppy disks in an OpenVMS
    Cluster system is supported, enabled by MSCP.

    For floppy disks to be served in an OpenVMS Cluster system,
    floppy disk names must conform to the naming conventions for
    port allocation class names. For more information about device
    naming with port allocation classes, refer to the OpenVMS Cluster
    Systems manual.

    OpenVMS VAX clients can access floppy disks served from OpenVMS
    Alpha Version 7.3 MSCP servers, but OpenVMS VAX systems cannot
    serve floppy disks. Client systems can be any version that
    supports port allocation classes.
