portchannel down on n2K with vpc

I am not sure why my port-channel is down and inactive:

I have a cat6509 with L3 LACP on 2 ports. Each port connected to a N2K to simulate VPC on a server.

On the 6509 side everything is fine. all ports are up and the L3 etherchannel is up too.

on Both n2K, it is showing that the physical ports are up but the port-chanel is down


Any idea??

Re: portchannel down on n2K with vpc

Can you send 'show port-c sum' and 'show vpc' as well?
