I have a Hyper V guest Cluster consisting of two Server 2012 R2 VMs with SQL 2016 setup as a failover cluster. The cluster has four SQL instances on it. After installing the first instance, everything was working fine. But when I installed a second, instance, and then all the rest, none of the instances will drain/failover other than the very first instance I installed. The cluster validation comes both fine other than I don't have two network paths, but that is not an issue in this case. Below is the list of cluster errors I get when when I try to drain an instance over:
Both servers all completely patched and are brand new builds. When I drain the first instance that I setup on the cluster, I have no problems, it works just like it is supposed to. It is just the other three that fail. It does not seem to be related to a host since there are two instances on each server, but only one of the four will move and it easily moves back and forth.
Does anybody have any ideas what could be going on here?
Thank you,
Ryan
