well...well... well...

 

I wanted to provide feedback for the resolution of my problem. Hopefully, it will help someone down the line.

 

If you have ever resolved a problem by accident, I know I have. I found the problem to be channel-group id on port channel interface membership. The LTM channel-group number must be the same on both Nexus 7k. I was following the ASA port-group id style. I discovered by accident when one LTM was taken off, then I connected sinlge LTM to both nexus 7k, everything came up. Then I said dawn it. I brought the second LTM back and criss-crossed each everything worked fine. Solution: Each LTM must have identical channel-group number on each Nexus 7k. For ASA, this is not the case when you criss-cross connect.
