Hi,
In Failover Clustering it is possible to tune settings like SameSubnetDelay and SameSubnetThreshold. For example, configuring SameSubnetDelay to a value of 1 and SameSubnetThreshold to 10 will allow the hearbeat feature to miss communication for 10 seconds between the nodes.
My question is, what will happen when a cluster node with multiple NICs (no teaming) looses NIC connectivity due to link loss or hardware failure. Will this trigger a node failure causing workloads to fail over?
As an example, think of a standard Hyper-V cluster node configured with separate networks for Management, CSV and Live Migration. If for example the CSV NIC on one node looses connectivity (the physical cable is being unplugged), will this trigger a node failure or will CSV simply fail over to another NIC based on network priorization?
I know the story will be different when NIC teaming is involved, but this question is related to Windows Server 2008 R2 Hyper-V clustering.
