We have three separate VMware SQL 2016 AlwaysOn clusters running on vShere 5.1. We noticed on all three clusters whenever we'd fail over a Availability Group to a second node within the same VLAN and running
on the same ESX host, that the resources would not become available until a 15 minute time-out period. If we fail over the same AG group to a host in another building the resources are immediately available.
This only happens on the same VLAN. So we opened a ticket with Microsoft and they ran a trace and stated the arp request is being sent out but no replies are being returned. Is this a vSphere issue?
Where in the process does VMware update the arp table?
