/sys$common/syshlp/helplib.hlb Sys Parameters, MC_SERVICES_P0  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    (Alpha only) MC_SERVICES_P0 controls whether other MEMORY CHANNEL
    nodes in the cluster continue to run if this node bugchecks or
    shuts down.

    A value of 1 causes other nodes in the MEMORY CHANNEL cluster to
    crash with bugcheck code MC_FORCED_CRASH if this node bugchecks
    or shuts down.

    The default value is 0. A setting of 1 is intended only for
    debugging purposes; the parameter should otherwise be left at
    its default value.

    MC_SERVICES_P0 is a DYNAMIC parameter.
