VMS Help LANCP, DEFINE, NODE, Qualifiers, /BOOT_TYPE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /BOOT_TYPE=boot-option
       /NOBOOT_TYPE

    Indicates the type of processing required for downline load
    requests. You can specify one of the following keywords with
    this qualifier:

    o  VAX_SATELLITE-an OpenVMS Cluster VAX satellite boot

    o  ALPHA_SATELLITE-an OpenVMS Cluster Alpha satellite boot

    o  OTHER-the specified image; a noncluster satellite load that
       does not require additional data

    The distinction is necessary, because OpenVMS Cluster satellite
    loads require additional cluster-related data be appended to the
    load image given by the /FILE qualifier. The default value is
    OTHER.

    If you do not specify the /BOOT_TYPE qualifier, the setting
    remains unchanged. The /NOBOOT_TYPE qualifier clears the field.
