LACP on Cisco ACI

Hi there, looking for help with a 3 node Harvester cluster.

"I have two Harvester nodes in the same rack with cross-card LACP bonds connected to a Cisco vPC leaf pair. Even though these are two separate servers, the LACP Partner Key being returned by the switch is identical for both nodes. This causes a ‘Last Man Standing’ scenario where the second node to power up kills the first node’s connectivity. To me this confirms that the switch-side ports for both servers are accidentally assigned to the same vPC ID / Port-Channel, but my network colleague claims there are no errors in the Cisco ACI configuration.

Any one here with Harvester nodes living i ACI with 802.3ad bonds?

Thanks in advance - Kim
