I'm trying to confirm the conditions that will initiate a LIF failover. Aside from a whole node going down, will a LIF only failover if there is a link loss?
If that's the case, is there any other options I can employ to protect against the upstream switch failing but NOT taking a port offline? I can't use LACP across two switches in this environmment.

If you have multiple core and switch redudency, upstream switch failing should not be a problem in your network.
Ontap is not designed to handle such failure. that should be handled in your network design.
In a NAS environment, netapp controller is not aware or keeping track of the client status until client request reach netapp.
Let the controller do what it disigned/suppose to do rather than trying to fix everything with it.
Here is some failover policy you can configure on your LIFs..
And I can gurantee none of them handle an upstream switch failure.
