Hi Aris,
Thanks for ur quick response, I don't have any DNS installed in my cluster.
My only option is to create a script to monitor server B...if server B is
down the script must run to restart the heartbeat on server A. Here's my
script for that..and it is running however may problem pa....I only need to
run the script once on server A....How can I do that?...cron is not
advisable....include the script on the mon services is to bad. I've observed
that both mon and cron will run the script every min.......which cause my
browser to hang-up while browsing.....any suggestion......??
#!/bin/sh
host="192.168.0.201";
cnt=1;
filename="`ping -c $cnt -A $host | grep -o "Unreachable"`";
inactive1="Unreachable";
echo "$date";
echo "$host";
echo "$filename";
echo "$inactive1";
if [ $filename = $inactive1 ]; then
/etc/init.d/heartbeat restart
else
echo secondary server $host is up
fi
exit

Heartbeat is not responsible for the round-robin, it's the DNS.
secondly, heartbeat is used not to monitor the "backup" but to
monitor the "Primary"
create a script that will monitor the nodes in a cluster. if one
of them are dead then remove it on the round robin's list.
