Library /sys$common/syshlp/sysgen.hlb AUTOCONFIGURE, Qualifiers, /EXCLUDE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /EXCLUDE=(device-name[,...])

    Specifies the device types that you do not want automatically
    configured.

    You can specify a device-type code as shown in the table listed
    under the /SELECT qualifier. You can include a controller
    designation but not a unit number. If the controller designation
    is omitted, all devices of the specified type are excluded. The
    device-name specification defaults to all devices on the adapter.
    Do not use this qualifier with the /SELECT qualifier.
