The way I did it was to write a wrapper script for heartbeat. At boot, both systems are named scalix.domain.tld. When Heartbeat starts, it's actually called by a wrapper script, which does something like:
hostname -s scalix1.domain.tld # Sets the hostname to a unique string /etc/init.d/heartbeat start hostname s scalix.domain.tld # Sets it back to what Scalix requires it to be You'll need to set all of the appropriate entries up in /etc/hosts as well of course. Then I set the haresources as per normal: scalix1.domain.tld 192.168.1.10 scalix scalix-postgres scalix-tomcat EOF /etc/init.d/heartbeat-wrapper: #!/bin/bash # # /etc/rc.d/init.d/heartbeat-wrapper # # Copyright (c) 2008 Rubin Bennett # rbTechnologies, LLC <[email protected]> # # Starts the heartbeat daemon on a Heartbeat cluster for servers running Scalix groupware # The Scalix message store is *very* hostname sensitive, and so in order to get an HA pair # to run Scalix # This wrapper changes the hostname to allow heartbeat to start # then changes it back. # # chkconfig: - 65 35 # description: Wrapper srcipt for Heartbeat # processname: heartbeat # Source function library. . /etc/init.d/functions TMPHOSTNAME=scalix1.alliedprinting.com ORIGHOSTNAME=`hostname` test -x /etc/init.d/heartbeat || exit 0 RETVAL=0 prog="Heartbeat Failover Service" start() { echo $"Starting $prog: " echo "Changing hostname to $TMPHOSTNAME" hostname $TMPHOSTNAME echo "Starting heartbeat" /etc/init.d/heartbeat start echo "Changing hostname back to $ORIGHOSTNAME" hostname $ORIGHOSTNAME RETVAL=$? echo } stop() { echo $"Stopping $prog: " echo "Changing hostname to $TMPHOSTNAME" hostname $TMPHOSTNAME echo "Stopping heartbeat" /etc/init.d/heartbeat stop echo "Changing hostname back to $ORIGHOSTNAME" hostname $ORIGHOSTNAME RETVAL=$? echo } # # See how we were called. # case "$1" in start) start ;; stop) stop ;; reload|restart) stop start RETVAL=$? ;; *) echo $"Usage: $0 {condrestart|start|stop|restart|reload|status}" exit 1 esac exit $RETVAL EOF /etc/ha.d/ha.cf logfile /var/log/ha-log logfacility local0 bcast eth1 auto_failback off node scalix1.domain.tld node scalix2.domain.tld EOF Rubin Rubin Bennett rbTechnologies, LLC 80 Carleton Boulevard East Montpelier, VT 05651 (802)223-4448 http://thatitguy.com "Think for yourselves and let others enjoy the privilege to do so too."

It would be highly appreciated.
