Creates a service for a specified device or partition.

    Usage Rules:

    o  All devices must be mounted systemwide to prevent them from
       being dismounted when a process logs out.

    o  A device that has read/write service must be mounted /FOREIGN
       so that it is not visible to OpenVMS.

    o  A device that has read-only service must be mounted either
       /NOWRITE or /FOREIGN to OpenVMS so that no one can change it
       locally.

    o  A partition can be served off a disk mounted for either read-
       only or read/write access to OpenVMS.

    o  Support for partitions is limited in this release.
