VMS Help Sys Parameters, VAXCLUSTER  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    VAXCLUSTER controls loading of the cluster code. Specify one of
    the following:

    Value  Description

    0      Never form or join a cluster.
    1      Base decision of whether to form (or join) a cluster or to
           operate standalone on the presence of cluster hardware.

    The default value is 1.

    VAXCLUSTER is an AUTOGEN parameter.
