You will login to the node which has the cluster_mgmt lif (net int show). This lif can failover between nodes, and the default is that it is on the system-defined "clusterwide" failover group. That means the lif can end up on any data interface on any node (net int failover-groups show). Usually, the home interface is on the first node in the cluster that is installed. However, everything on the cluster_mgmt lif is customizable, so you may configure a different failover group, different home port, etc.
