Host to Fex (and Nexus) port channel configuration

[kanmagred]

Hi there

I have 2 Nexus 9K switches multi-homed to 2 Fexs. 

I have an issue with a host connecting to 2 ports of Fex (port channelled) - learning MAC address on Po but no cant reach the device on layer 3. When I shut down one of the interfces and remove the other from channel group, it works fine. Please help
