As the subject suggests we have a SQL failover cluster that only fails over one way when we down the SQL server. If we use the cluster manager to do a manual failover to both nodes it works.
The problem occurs when we power off node1 expecting it to fail over to node2, it takes the cluster offline and does not failover. If we start node1 back up the cluster comes back online having switched to node2.
There are no obvious errors in the logs.
The other way works fine.
OS: 2012R2
SQL Version: 2014SP1
Any suggestion welcome.
