Want to check anyone had successfully changed the listening port of SQL Server 2014 Failover Cluster?
I used following steps but kept failing to startup SQL Server cluster again:
1. Use Get-ClusterResource -Name "SQLCLSTNM" | Remove-ClusterCheckpoint -CryptoCheckpoint
2. Change port number through SQL Server Configuration Manager on each node
3. Use Get-ClusterResource -Name "SQLCLSTNM" | Add-ClusterCheckpoint -CryptoCheckpointName "Microsoft Enhanced Cryptographic Provider v1.0" -CryptoCheckpointType 1 -CryptoCheckpointKey "......"
I even tried to stop the SQL Server cluster role before I tried step 1. The SQL Server cluster always stopped after several minutes waiting for SQL Server service come online. During the startup, I have checked SQL Server service status. It was actually already started. After several minutes, SQL Server failover cluster role will fail. And the SQL Server service was also terminated without any message in the ERROR log, not even any informational message.
The cluster runs perfectly fine once I revert it back to use 1433 port.
This is a three nodes cluster, SQL Server 2014 SP1 running on Windows Server 2012 R2, cross two different subnets.
