# 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.
