Could this be because we turned off power to vmh-02 completely? We are 
testing to make sure that the HA VMs will be restarted on another host 
even if the host suffers complete hardware failure.

Here's the result (from both):

Getting status of IPMI:10.9.1.11...Spawning: '/usr/bin/ipmitool -I 
lanplus -H '10.9.1.11' -U 'ADMIN' -P '[set]' -v chassis power status'...
Chassis power = On
Done

Of course, the server is now up and running so this is expected.

See attached.
