#
# When properly installed, this script is invoked by the GPFS daemon during
# normal or abnormal shutdown cleanup processing.
#
# The script is invoked with one parameter which represents the status of
# the GPFS daemon.  The possible values are:
#   down    - this is normal shutdown processing as a result of a mmshutdown
#             command.  The GPFS daemon will not be restarted.
#   active  - this is abnormal shutdown processing as a result of some
#             unrecoverable condition.  The GPFS daemon will be restarted.
#
# If this is a normal shutdown, GPFS has already unmounted all file systems.
#
# If this is abnormal shutdown, GPFS leaves the file systems mounted and
# will attempt to remount them after the daemon restarts.  If you do not
# wish the file systems to be automatically remounted, add the appropriate
# umount commands in this script.
#
# You can also use this script to add any commands to clean up local state
# before the GPFS daemon restarts.
#
# If GPFS was started with the -T option (activate tracing) on the mmstartup
# command, trace records have already been cut prior to invoking this script.
# If you want to disable on a particular node the automatic trace handling,
# run the following command on the desired nodes:
#      touch /var/mmfs/etc/ignoreMMTRACE
#
# If you have disabled the automatic trace handling, or if you have started
# tracing with the mmtrace command, add the appropriate trace handling commands.
#
#
# To activate the code:
#
#   a) edit this script and make the appropriate changes
#   b) copy this script to /var/mmfs/etc/mmfsdown
#   c) ensure this script is executable (chmod +x /var/mmfs/etc/mmfsdown)
