VMS Help INITIALIZE, /QUEUE, Qualifiers, /ON  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /ON=[node::]device[:] (printer, terminal, server queue)
       /ON=node:: (batch queue)

    Specifies the node or device, or both, on which this execution
    queue is located. For batch execution queues, you can specify
    only the node name. For output execution queues, you can include
    both the node name and the device name. By default, a queue
    executes on the same node from which you start the queue. The
    default device parameter is the same as the queue name.

    The node name is used in OpenVMS Cluster systems; it must match
    the node name specified by the system parameter SCSNODE for the
    OpenVMS computer on which the queue executes.

    You cannot use the /ON qualifier with the /AUTOSTART_ON or
    /GENERIC qualifier; however, if you are reinitializing an
    existing queue, you can specify the /ON qualifier for a queue
    previously created or started with the /AUTOSTART_ON qualifier.
    Doing so overrides the /AUTOSTART_ON option and makes the queue a
    nonautostart queue.
