I just setup SQL Server 2012 (on Windows Server 2012) Always On feature and have a problem with connecting to SQL Server Listener from non-primary node (it works from primary node though).

Here is the scenario: 2 nodes in different subnets: SQL1 10.0.2.11 (primary) SQL2 10.0.6.11 (secondary) Listener: Name: SQLPROD1 Port: 1433 Subnets IP address 10.0.2.0/24 10.0.2.102 10.0.6.0/24 10.0.6.102

I can connect to SQLPROD1 in SSMS on primary node (either SQL1 or SQL2) but can't connect (not even ping) SQLPROD1 from secondary or from any other client in the network. I checked firewall and it doesn't seem to be the cause of the problem. I can ping SQL1 or SQL2 from any client but can't ping SQLPROD1.

Beside this, everything else works in Always On. I can successfully fail-over and see databases on other node.

Can you please help

Thanks

Are you sure that the hostname is resolving to the right IP address, or resolving at all? That would be my first verification. –  Thomas Stringer Mar 7 at 18:45
