Valid for x86-64 systems only.

    Updates the list of alternate devices where system crash dumps
    can be written.

    This command does not create a dump file on any specified
    device; the recommended method is to use the CREATE command in
    the SYSGEN utility. If a specified device is not mounted or
    no dump file is found there, a warning will be output.

    The updated list of devices is saved in system memory for
    immediate use, and in the file SYS$MANAGER:SYS$DUMP_CONFIG.DAT
    for subsequent system reboots.
