/sys$common/syshlp/helplib.hlb START, /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.

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

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