How does RHEV update multipath.conf
We are primarily a HDS shop and we have a /etc/multipath.conf that we have optimized and push out to our hosts via Satellite. I recently spun up 2 nodes with RHEL 6.4 and then configured them to be RHEV Hypervisors, which replaced the multipath.conf.
This is the resulting output (which may actually be correct)

I was expecting to see something like (both active/ready)
