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