I'm running into some difficulty getting the AG Listener created for a 3 node cluster where node 3 is on a separate subnet.
I'm encountering an error that states
Create failed for Availability Group Listener 'AO-AGL' None of the IP addresses configured for the availability group listener can be hosted by the server 'NODE3'. Either configure a public cluster network on which one of the specified IP addresses can be hosted, or add another listener IP address which can be hosted on a public cluster network for this server. (Microsoft SQL Server, Error: 19456)
How do I handle this situation. This blog post (http://mohdsohail.wordpress.com/2013/02/14/adding-seconday-replica/) is the only thing I could find for reference and it isn't very clear on the solution. He states adding a second IP address. However, what exactly does this look like in DNS? Do I have one DNS hostname with two IP addresses?
