We did all of the above (NV4.1, HSRP, and discover by loopbacks in seed
file) and all was working just fine.
Like you, we made sure "discover loopbacks" was on in the netmon
configuration, that the routers were discovered via loopbacks. We also
specified subnet ranges to manage that didn't include any router interfaces
of any kind. (I.E. "10.2.95.1" in the seedfile for the router loopback,
and "10.3.95.11-254" for the subnet that router supported.)
The only glitch was duplicate IP address events for HSRP addresses after a
fail-over. Not a huge problem, and quickly fixed.
We went to NV 5.0 right after U451880, so I can't say I suffered the same
problem you have. But I can say it should be working like you want it to.
I'd take it to Tivoli support to fix or clarify.
