We had 5 SQL Server 2012 servers configured with AlwaysOn.
A few days ago we dismissed 2 of them, we removed them from the availability group and then stopped SQL services. We need to reuse these servers for other purposes.
I need to know how to remove them also from the Windows Failover Cluster on which AlwaysOn is based.
Is it enough to click on the nodes and press "stop cluster service" and then "evict"?
Or there is something to do also with the SQL server installation?
Please note that the two servers will be formatted, so local SQL installation can be destroyed.
