2 node clustering in Redhat
 
I made 2 node redhat cluster using luci,ricci,rgmanager and cman, If i shutdown or restart or disable the eth0 means the cluster services automatically transferred to node 2, But If I stop the network(service network stop) or directly power off the node 1 means the cluster service is not transferred to node 2.
Here Each node have 2 IP, one for local network and one for heartbeat ip, (And I using one common virtual ip).
Here I am using 2 virtual redhat5 server and shared iscsi storage.
And give me any idea, if I am directly turn off (UPS down) node1 means the cluster service automatically should go to node2. and my cluster.conf file is

<?xml version="1.0"?>
<cluster alias="new-cluster" config_version="41" name="new-cluster">
<fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/>
<clusternodes>
<clusternode name="rheltest1.arowana.com" nodeid="1" votes="1">
<fence/>
</clusternode>
<clusternode name="rheltest2.arowana.com" nodeid="2" votes="1">
<fence/>
</clusternode>
</clusternodes>
<cman expected_votes="1" two_node="1"/>

<failoverdomainnode name="rheltest2.arowana.com" priority="2"/>
</failoverdomain>
</failoverdomains>

</resources>

</service>
</rm>
</cluster>

Please use standard tool to configure cluster in linux. Like in Redhat, luci and ricci.

Your configuration seems to be incomplete but to configure failover domain in below cluster configuration.

Modify service section

<service autostart="1" domain="star" exclusive="1" name="cluster" recovery="relocate" name="ipservice">
<ip ref="192.168.0.245"/>
</service>
