    Input Save Set Device Name field

    Use the "Save Set Device Name" field to specify the name of the disk
    or tape device on which the save set is located.  This must be a
    different device than  the output device when you are restoring an
    entire volume.

    You can specify either a logical device name or a physical device
    name. The device must not be allocated by any other user.  Press PF3
    to display a box that lists available devices.  Selecting a device
    from this box places the list entry in the "Save Set Device Name"
    field; if you do not want to select a device, press PF3 again (or
    Ctrl/Z).  For more information, see "Physical and logical device
    names" in the "Concepts ..." help topic.
