10.133.217.51 127.0.0.1 UGHS 0 342 lo0 - -

I keep finding routes like the above in routing tables on a server running hacmp. How do I prevent them from entering the routing table at all?

This may not be related to HACMP. If you're running AIX 5.x then this is normal behavior. The system redirects internal traffic to the loopback interface. Is 10.133.217.51 by any chance one of your interfaces on the machine?

That's correct...it is. So, are there any adverse effects of these addtitional routes

No, on the contrary, I would assume. With these routes AIX redirect packets destined to the same machine through the loopback interface instead of passing them down to the Ethernet device driver (or whatever type of card you have on your box) and I guess the reason for this is performance.
