More Information

For more information about the products or tools that automatically check for this condition on your instance of SQL Server and on the versions of the SQL Server product, see the following table:

Rule software



Rule title



Rule description



Product versions against which the rule is evaluated
SQL Server 2008 R2 Best Practice Analyzer (SQL Server 2008 R2 BPA)










This system experienced problems related to I/O requests.

This system experienced unexpected shutdowns






The SQL Server 2008 R2 Best Practice Analyzer (SQL Server 2008 R2 BPA) provides a rule to detect if any of the events listed in the Symptoms section are found in the Windows System Event Log. The SQL Server 2008 R2 BPA supports both SQL Server 2008 and SQL Server 2008 R2. If you run the BPA tool and encounter an Error with the title of Engine - This system experienced problems related to I/O requests, then you have one of the EventID values as listed in the Symptoms section of this article in your Windows System Event Log. In all cases, the correct EventID is detected based on the message text or source (these EventID values can be used with other sources). BPA does not filter on any date/time so it will report the number of occurrences of these events in your current Event Log. 

Another rule for SQL Server 2008 R2 BPA detects specifically EventID=6008 which is for unexpected system shutdowns. In some situations, an unexpected system shutdown can lead to consistency problems such as torn pages. This condition will be encountered if BPA detects an Error with the title of Engine - This system experienced unexpected shutdowns		SQL Server 2008
SQL Server 2008 R2
