SQL SERVER – Clustered SQL Resource Not Coming Online
When I was on-site for the performance tuning workshop, few DBAs suddenly got call as there was an unexpected downtime of SQL Server. As per them, after some maintenance activities were scheduled, the SQL Server resource failed to come online on both nodes.

Let us see an error related to clustered SQL Resource not coming online.

This blog is an outcome of that work done. Let us see the error related to Arithmetic Overflow Error.
