Folks,
I have a 4 node Hyper-V 2012 Failover Cluster.
The networking is
1*1GB Nic for Management
4*1GB Team for VM Comms
3*1GB Team for iSCSI, Heartbeat, Backups etc
2* FC HBA for storage
The problem here is that random VMS are losing connectivity. The VM is up; the nic looks connected, however it does not see its default gateway.
The problem VM can ping any other VM on that Node.
If I do an "arp -a -v" on the VM it has an invalid arp entry of 00-00-00-00-00-00
If I move the VM to another node the nic kicks back to life.
Any ideas on what could be causing this.
Cheers
