ISE Guest Portal Failover For New Requests

I have one controller and two ISE 1.2 nodes (primary and secondary)  for resiliency, not capacity.  Each ISE node has one interface for Management and one interface for Guest Portal.  PSN is active on both nodes.  The WLC chooses the ISE node (with fallback) for authentication.  For guest authentication, the user should be redirected to one of the two Guest Portals. What is the best method for choosing and correctly redirecting the user to the Guest Portal (including when one is down).  Is there another/simpler solution than a load-balancer for this scenario. Node Groups are for pending sessions and I need a solution for new sessions.

Thanks.

You dont need to do that, once the WLC has deemed a PSN down, new mab requests are sent to the next psn in your radius list on the wlc, and the other psn will reply with its own hostname in the redirect url.
