Hi all,
One client just set up Windows 2012 R2 clustering and SQL 2012 always on. two site A and B. At site A(producton site), 4 nodes . Two nodes have two NICs (one for private replication; another for client and cluster communication); Two nodes with one public NIC. cluster node constantly removed from active cluster membership event 1135. private network is down error; same as http://blogs.technet.com/b/askcore/archive/2012/02/08/having-a-problem-with-nodes-being-removed-from-active-failover-cluster-membership.aspx
I do not understand how these 4 nodes communicate each other since (two nodes have one private and one public IPs; other two have only one public IP). can anyone let me know how heartbeats work among these 4 nodes? I do not think it is driver issue since two nodes are physical and two nodes are virtual.
How should I make these errors go away? do I need to adjust these values according to http://www.sqlhammer.com/blog/set-windows-failover-cluster-timeout-thresholds/?
BTW, can anyone let me know how heartbeats work among th
Thank you very much!
