Hello
Need one hint on HA to a prob i have in a test env.
- Cluster of 2x nodes SQL Server 2016 @ Windows server 2012R2
- Have 3 databases in HA group and running fine.
- Did some switchover within the SQL and runned fine so far.
- Did tests to the Windows server and they were not so good, on of the tests was to disconnect primary Replica _network card_ on the cluster and Everything stopped.
- Got only one Network card per Node
- If i have Node1 as primary and fail it over, the cluster crashes
- If i have Node 2 as primary and fail it over, the cluster stays ok and the SQL HA is pointed to the node1
The secondary replica that should be taking over, did not, and left the Windows Server Failover Cluster
The databases become unused on Secondary Replica.
To repair this, i do: turn back the network on primary replica, re-add the secondary replica to the cluster, make the Role to go Online on the Secondary Replica. Seems very odd
Im running this infra on a VM environment.
And i'm doing my first SQL Server HA setup.
What am i missing?
Thanks in advance
