Having a read through /var/log/messages for possible causes would be a good start.
do I have to configure manually load balanced ip 10.30.30.92 as an alias ip on both sides or is it done automatically by redhat cluster ?
RHCS will automatically assign the IP to an interface that is on the same subnet. You most definitely shouldn't create the IP manually on any of the nodes.
I just made a simple try with apache but I do not find anywhere reference to the start/stop script for apache in the examples, is that normal ?? do you have some best practice regarding this picture ??
I'm not familiar with the <apache> tag in cluster.conf, I usually configure most things as init script resources.
