    4 # The 3ware controller offers a choice of options related to handling of
    5 # mirror consistency in shutdown situations.
    6 #
    7 # If TWE_SHUTDOWN_NOTIFICATION is defined, the driver will inform the 
    8 # controller on clean shutdown.  On reboot after an unclean shutdown, the 
    9 # controller will perform a complete mirror rebuild.  This is the most
   10 # "safe" configuration, but it imposes a severe performance penalty in the
   11 # event of an unexpected reboot.
   12 #
   13 # In the alternate configuration, the controller assumes that all writes to
   14 # a mirror complete successfully.  In the case of an unclean shutdown,
   15 # mirror corruption may occur if the controller is reset or power is lost
   16 # during a disk write.  This configuration is more suitable if the system
   17 # has reliable power, but may be unstable for other reasons.
