Edwin10001,   You are correct about how it should work and shouldn't have gone down. [URL] Now troubleshooting why it went down is out of our scope, but if it is still down checking connections and logs would be the best place to start.   Let me know if this helps.
Hi,  I have 2 switches peered with VLT. VLT port channel 10 (LACP) is configured to Storage Node with physical links to the 2 switches. 2 physical trunk links from the 2 switches (not port-channel) configured to Host A running on hyper-v (Nic teaming mode on switch independent). When one of the storage node NIC is down, the interface and port channel 10 of the 2nd switch went down as well, leaving some of the VMs in Host A tied to 2nd switch not able to communicate with the storage node. VMs in host A tied to the 1st switch is still able to communicate to the storage node with the interface and port channel 10 still up. Shouldn't the VMs which is tied to the 2nd switch be able to pass traffic through VLT to port channel 10 of the 1st switch in order to reach the storage node?
