Thank you for your support.

seem the lab is bug. I don't certainly. I have to connect the link before I start device such I can configure port channel to success.

Yes it sure bug' I face the same in my lab exactly same 

N9k refused up po' but I found if I config spt mst the issue is solve.

Do show spanning tree you will see that PO and port members is missing from spanning tree table!!
