How to determine why a lif is on a certain port or node

When lifs failover based on various rules and scenarios, the location of a lif is not always as expected.

Incorrect lif failover settings will cause lifs to migrate to ports where they might not be accessible.
A link break in the environment (like a switch power reset) will trigger a lif migration, which might have gone unnoticed.
A storage failover will also cause lifs to migrate. If auto-giveback is enabled, an SFO event might have gone unnoticed resulting in lifs not being home.
