I just had to sit and trace all the cables to make sure the tx/rx lined up for the right circuits as well as hitting the right patch panel ports. Once all that got aligned nicely things started working magically.
Yep, ports in an "up" state, but LACP not working is the sign of bad cabling: had been hit by this overnight once when I was preparing to leave the facilities next day for conference, but ought to make 10G for the new servers working. Took around 1/2 hour to sense what happened at that time (tx was going to, say, port A and rx -- to port B, but overall all ports were receiving tx and rx) and 3 hours for rewiring and swearing: probably I am more skilled in the former than in the latter ;) Thought that you had checked this in the first place; my bad.
