Maybe my explanation was not that clear. Here is my configuration

crm configuration show

node $id="17435146" pogcupsvr
node $id="34212362" pogcupsvr2
primitive apache ocf:heartbeat:apache \
         params configfile="/etc/httpd/conf/httpd.conf" \
         op start interval="0" timeout="40s" \
         op stop interval="0" timeout="60s"
primitive clusterip ocf:heartbeat:IPaddr2 \
         params ip="" cidr_netmask="24" nic="eth0" \
         meta target-role="Started"
property $id="cib-bootstrap-options" \
dc-version="1.1.7-2.mga1-ee0730e13d124c3d58f00016c3376a1de5323cff" \
         cluster-infrastructure="corosync" \
         stonith-enabled="false" \
rsc_defaults $id="rsc-options" \

So I've started primary node (pogcupsvr). Configuration was checked and 
ok. Then started the second node (pogcupsvr2). This time all the 
configuration looked ok, no error but when I checked the network 
configuration, eth0 was up on both nodes with same IP address of course, 
instead of having it up only on primary node.

What I was expected (and in all other tests it was ok ) is that eth0 was 
up only on primary node and used by apache server.
