     # The 3ware controller offers a choice of options related to handling of
    # mirror consistency in shutdown situations.
    #
    # If TWE_SHUTDOWN_NOTIFICATION is defined, the driver will inform the 
    # controller on clean shutdown.  On reboot after an unclean shutdown, the 
    # controller will perform a complete mirror rebuild.  This is the most
    # "safe" configuration, but it imposes a severe performance penalty in the
    # event of an unexpected reboot.
    #
    # In the alternate configuration, the controller assumes that all writes to
    # a mirror complete successfully.  In the case of an unclean shutdown,
    # mirror corruption may occur if the controller is reset or power is lost
    # during a disk write.  This configuration is more suitable if the system
    # has reliable power, but may be unstable for other reasons.
