fence_ipmilan works with just about every IPMI-based out of band 
management interface. Most of those branded ones, like DRAC, RSA, iLO, 
etc are fundamentally based on IPMI. I've used fence_ipmilan on iLO 
personally and it's fine.

If you can show what 'ipmitool' command you use that can show if the 
peer is powered on or off, then you should be able to translate it quite 
easily to a matching fence_ipmilan call (check man fence_ipmilan for the 
switches). Once you can check the power status of the peer(s) with 
fence_ipmilan, you're 95% of the way there.
