When you try to create a high-availability group in Microsoft SQL Server 2012, you receive the following error message:
Msg 41131, Level 16, State 0, Line 2
Failed to bring availability group 'availability_group' online. The operation timed out. Verify that the local Windows Server Failover Clustering (WSFC) node is online. Then verify that the availability group resource exists in the WSFC cluster. If the problem persists, you might need to drop the availability group and create it again.
This issue occurs if the [NT AUTHORITY\SYSTEM] account is missing from the SQL Server logon or if the account lacks the necessary permissions to create the high-availability group.
To resolve this issue, use one of the following methods.
Method 1: Use manual steps
The [NT AUTHORITY\SYSTEM] account is used by SQL Server AlwaysOn health detection to connect to the SQL Server computer and to monitor health. When you create an availability group, health detection is initiated when the primary replica in the availability group comes online. If the [NT AUTHORITY\SYSTEM] account does not exist or does not have sufficient permissions, health detection cannot be initiated, and the availability group cannot come online during the creation process.
Make sure that these permissions exist on each SQL Server computer that could host the primary replica of the availability group.
Note The Resource Host Monitor Service process (RHS.exe) that hosts SQL Resource.dll can be run only under a System account.
