Dear
I have two disco switches N5K which run VPC and connected together to non-vss Cisco switches 6500. The Port channels between 6k and N5k are up , but i cannot see any vlans under spanning-tree also if i did show interface trunk we got all vlans under err-disable. We have enable only
Please check attached.

Hi , why are there no vlans allowed/configured on the vpc peer-link between the 5ks ?
vlans are usually allowed on this trunk as example below from one of my dcs , can you post the show vlan from each switch and show vpc brief as well please
