#	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
#

#
#
#	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

#	[ttl]		the ttl value for outbound heartbeats.  this effects

#	About boolean values...
#
#	Any of the following case-insensitive values will work for true:
#		true, on, yes, y, 1
#	Any of the following case-insensitive values will work for false:
#		false, off, no, n, 0

#
#
#	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

#	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.
