Ok I see you are using fence_ilo but I don't see a messages snip.  The messages snip will tell us exactly what is going on, there isn't much I can do without it.  You may want to try running:

# fence_node rhel-cluster-node1.mgmt.local

>From node 1:
# fence_node rhel-cluster-node2.mgmt.local

This should cause your nodes to get rebooted, if it doesn't then there is a problem with your fencing config.  A snip of your messages file from one of these events would help out here.
