Hi All.

We have 2x 2022 HyperV servers with a clustered SQL server running on each host.

Yesterday i shut down all the vm's on Host 2 and patched it to latest firmware etc. When I brought the SQL servers back up, SQL Server 2 in the failover cluster was in a state of "Quarantined" and had a red arrow. Also the Always on HA replication was not working.

So, i ran Start-ClusterNode -ClearQuarantine powershell command on SQL2. Now SQL2 is showing a green arrow and always on HA is working properly. All green.

But, the Failover Cluster still shows Quarantined. Its almost like I just need to reset the state or something. Does anyone have any ideas? Thanks.
