Each node has 2 NICs, one for the client and management network, and one for the heartbeat network.The nodes are running Server 2016, SQL 2012 and Microsoft Failover Cluster services.For the sake of this blog post lets call the 2 nodes A and B.Recently I found myself troubleshooting a MS Failover cluster deployment which wasn’t behaving quite in this manner. The Layer 3 switch / router then updates the MAC address in the ARP table and packets are routed to the node which claimed the cluster roles. This was a particularly odd issue which I had never experienced before so I thought it’s worth blogging about it.ĭuring a normal MS Failover Cluster failover operation, the node calming the cluster roles sends out a GARP request to notify the networking infrastructure of the MAC address change.
