We have two paths to the arrays (two switches). They installed on one switch and then the other. At this time our production server lost access to the tempdb with these error messages:- - - - SQL Server has encountered 1 occurrence(s) of I/O requests taking longer than 15 seconds to complete on file [J:\Logs\Budget_log.ldf] in database [Budget] (7).

SQL 2000 just sat there until I restarted sql service. Anyone have insight on this. I'm sure our SAN guys will have some ideas, but I was curious.Thanks Post #457638 Roy ErnestRoy Ernest Posted Tuesday, February 19, 2008 2:19 PM SSCrazy Group: General Forum Members Last Login: Yesterday @ 7:19 AM Points: 2,382, Visits: 6,850 We had one issue like that.

Additional messages in operating system the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error operating system error can be caused by many factors; for more information, see SQL Server Books Online. Cause. We had some issues with the FLARE storage operating environment of our EMC CLARiiON CX3. FLARE was disconnecting unexpectedly servers connected to the CX3. Solution. We updated FLARE on the CX3 and it solved the problem. During this update process, computers connected to the SAN experienced temporarily some disconnections. After the update was applied, we restarted the server where the SQL Server instance is installed. Finally we ran a consistency check on the drive attached to the CX3 and on every database on the SQL Server instance. .Send mail to webmaster@sqlcoffee.com with questions or comments about this web site.
