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

    SCSNODE specifies the name of the computer. This parameter is not
    dynamic.

    Specify SCSNODE as a string of up to six characters. Enclose the
    string in quotation marks.

    If the computer is in an OpenVMS Cluster, specify a value that is
    unique within the cluster. Do not specify the null string.

    If the computer is running DECnet for OpenVMS, the value must be
    the same as the DECnet node name.

    SCSNODE has the AUTOGEN and GEN attributes.
