It means the LIF is not currently residing on it's home port (IE it has been migrated to a different node and or port in the cluster).
Check the output of the following command on your cluster:
network interface show -fields is-home, home-port, home-node, curr-node, curr-port
If the the "is-home" field is false then to resolve the warning you can either use the "network interface migrate" or "network interface revert" command to ensure the LIF resides on its home port and node. You can also configure your LIF to auto revert to it's home port\node. EG
