How can the F5 inform a node it is about to become the primary active node?

Thanks Eric.

So the monitor will monitor the nodes in the pool and you are saying if the health check call for one fails then I could call the URL to start services on the next node to be come the active node?

How would I know which secondary node the F5 is going to pick to become the new primary? (So I can call it to tell it to start its processes)

Thanks, Mike
