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

       /AUTOSTART_ON=(node::[device][,...])

    Designates the queue as an autostart execution queue and
    specifies the node, or node and device, on which the queue can
    be located. For batch queues, only node is applicable.

    In a cluster, you can specify more than one node (or node and
    device) on which a queue can run, in the preferred order in which
    nodes should claim the queue. This allows the queue to fail over
    to another node if the node on which the queue is running leaves
    the cluster.

    When you enter the INITIALIZE/QUEUE command with the /AUTOSTART_
    ON qualifier, you must initially activate the queue for
    autostart, either by specifying the /START qualifier with the
    INITIALIZE/QUEUE command or by entering a START/QUEUE command.
    However, the queue will not begin processing jobs until the
    ENABLE AUTOSTART/QUEUES command is entered for a node on which
    the queue can run.

    This qualifier cannot be used in conjunction with the /ON
    or /GENERIC qualifier. However, if you are reinitializing an
    existing queue, you can specify the /AUTOSTART_ON qualifier for a
    queue previously created or started with the /ON qualifier. Doing
    so overrides the /ON qualifier and makes the queue an autostart
    queue.

    For more information about autostart queues, refer to the chapter
    about queues in OpenVMS System Manager's Manual, Volume 1:
    Essentials.
