SQL SERVER – Unable to Bring SQL Cluster Resource Online – Online Pending and then Failed
Here is the situation which my client explained and I was asked for help about SQL Cluster Resource.
Hi Pinal,
We are having 2 node windows cluster having 3 SQL Server instances clustered running on Windows 2012 R2 on VMware. We have one instance that will start from the services.msc but not from the Failover Cluster Manager when attempting to bring the service online. In reality the services start because during the ‘Online pending’ I am able to connect and query the databases on that instance, although it is in the ‘Online pending’ state.
Do you know what could be the problem?
