multi subnet AG

  • We have configured multi subnet AG and assigned two IPs for the listener one each in different subnet. When we tried to failover to a node in different subnet, we cannot connect to the listener. The cluster is not able to control the dynamic DNS record creation for listener. Only one is getting registered. Any suggestions?

  • what error do you see in eventlog?

  • i havent found any errors or warnings either in cluster logs or event viewer. But found a message after listener in failover cluster manager as cannot resolve name.

  • The exact issue --

    during a failover in which the primary replica moves from one subnet to the other, the old IP address that was online is not getting unregistered, and the new IP address that is brought online is not getting registered. So we were not able to connect to the listener after failover.

    Same issue reported here--
