Something is breaking the network during the shutdown, a fence is being 
called and both nodes are killing the other, causing a dual fence. So 
you have a set of problems, I think.

First, disable acpid on both nodes.

Second, change the quoted line (only) to:

<device lanplus = "" name="inspuripmi" delay="15" action ="reboot"/>

If I am right, this will mean that 192.168.10.10 will stay up (fence) .11

Third, what bonding mode are you using? I would only use mode=1.

Forth, please set the node names to match 'uname -n' on both nodes. Be 
sure the names translate to the IPs you want (via /etc/hosts, ideally).

Fifth, as Sivaji suggested, please put switch(es) between the nodes.

If it still tries to fence when a node shuts down (watch 
/var/log/messages and look for 'fencing node ...'), please paste your 
logs from both nodes.
