#
# There are lots of options in this file. All you have to have is a set
# of nodes listed {"node ...} one of {serial, bcast, mcast, or ucast},
# and a value for "auto_failback".
#
# ATTENTION: As the configuration file is read line by line,
# THE ORDER OF DIRECTIVE MATTERS!
#
# In particular, make sure that the udpport, serial baud rate
# etc. are set before the heartbeat media are defined!
# debug and log file directives go into effect when they
# are encountered.
#
# All will be fine if you keep them ordered as in this example.
#
#
# Note on logging:
# If all of debugfile, logfile and logfacility are not defined,
# logging is the same as use_logd yes. In other case, they are
# respectively effective. if detering the logging to syslog,
# logfacility must be "none".
#
# File to write debug messages to
#debugfile /var/log/ha-debug
#
#
# File to write other messages to
#
#logfile /var/log/ha-log
#
#
# Facility to use for syslog()/logger
#
logfacility local0

#
# A note on specifying "how long" times below...
#
# The default time unit is seconds
# 10 means ten seconds
#
# You can also specify them in milliseconds
# 1500ms means 1.5 seconds
#
#
# keepalive: how long between heartbeats?
#
#keepalive 2
#
# deadtime: how long-to-declare-host-dead?
#
# If you set this too low you will get the problematic
# split-brain (or cluster partition) problem.
# See the FAQ for how to use warntime to tune deadtime.
#
#deadtime 30
#
# warntime: how long before issuing "late heartbeat" warning?
# See the FAQ for how to use warntime to tune deadtime.
#
#warntime 10
#
#
# Very first dead time (initdead)
#
# On some machines/OSes, etc. the network takes a while to come up
# and start working right after you've been rebooted. As a result
# we have a separate dead time for when things first come up.
# It should be at least twice the normal dead time.

# [port] udp port to sendto/rcvfrom (set this value to the
# same value as "udpport" above)
# [ttl] the ttl value for outbound heartbeats. this effects
# how far the multicast packet will propagate. (0-255)
# Must be greater than zero.
# [loop] toggles loopback for outbound multicast heartbeats.
# if enabled, an outbound packet will be looped back and
# received by the interface it was sent on. (0 or 1)
# Set this value to zero.

# About boolean values...

# Any of the following case-insensitive values will work for true:

#
# auto_failback: determines whether a resource will
# automatically fail back to its "primary" node, or remain
# on whatever node is serving it until that node fails, or
# an administrator intervenes.
#
# The possible values for auto_failback are:
# on - enable automatic failbacks
# off - disable automatic failbacks
# legacy - enable automatic failbacks in systems
# where all nodes do not yet support
# the auto_failback option.
#
# auto_failback "on" and "off" are backwards compatible with the old
# "nice_failback on" setting.
#
# See the FAQ for information on how to convert
# from "legacy" to "on" without a flash cut.
# (i.e., using a "rolling upgrade" process)
#
# The default value for auto_failback is "legacy", which
# will issue a warning at startup. So, make sure you put
# an auto_failback directive in your ha.cf file.
# (note: auto_failback can be any boolean or "legacy")

#
# Basic STONITH support
# Using this directive assumes that there is one stonith
# device in the cluster. Parameters to this device are
# read from a configuration file. The format of this line is:
#
# stonith <stonith_type> <configfile>
#
# NOTE: it is up to you to maintain this file on each node in the
# cluster!
#
#stonith baytech /etc/ha.d/conf/stonith.baytech
#
# STONITH support
# You can configure multiple stonith devices using this directive.
# The format of the line is:
# stonith_host <hostfrom> <stonith_type> <params...>
# <hostfrom> is the machine the stonith device is attached
# to or * to mean it is accessible from any host.
# <stonith_type> is the type of stonith device (a list of
# supported drives is in /usr/lib/stonith.)
# <params...> are driver specific parameters. To see the
# format for a particular device, run:
# stonith -l -t <stonith_type>
#
#
# Note that if you put your stonith device access information in
# here, and you make this file publically readable, you're asking
# for a denial of service attack ;-)
#
# To get a list of supported stonith devices, run
# stonith -L
# For detailed information on which stonith devices are supported
# and their detailed configuration options, run this command:
# stonith -h
#
#stonith_host * baytech 10.0.0.3 mylogin mysecretpassword
#stonith_host ken3 rps10 /dev/ttyS1 kathy 0
#stonith_host kathy rps10 /dev/ttyS1 ken3 0
#
# Watchdog is the watchdog timer. If our own heart doesn't beat for
# a minute, then our machine will reboot.
# NOTE: If you are using the software watchdog, you very likely
# wish to load the module with the parameter "nowayout=0" or
# compile it without CONFIG_WATCHDOG_NOWAYOUT set. Otherwise even
# an orderly shutdown of heartbeat will trigger a reboot, which is
# very likely NOT what you want.

# You can obtain HBAAPI from http://hbaapi.sourceforge.net. You need
# to get the library specific to your HBA directly from the vender
# To install HBAAPI stuff, all You need to do is to compile the common
# part you obtained from the sourceforge. This will produce libHBAAPI.so
# which you need to copy to /usr/lib. You need also copy hbaapi.h to
# /usr/include.
#
# The fc-card-name is the name obtained from the hbaapitest program
# that is part of the hbaapi package. Running hbaapitest will produce
# a verbose output. One of the first line is similar to:
# Apapter number 0 is named: qlogic-qla2200-0
# Here fc-card-name is qlogic-qla2200-0.
