Hello All,

Environment:
Windows 2000 sp4
SQL Server 2000 sp4 build 2187
EMC SAN attached storage.

We cannot move off this platform until the third-party vendor certifies their application. :-(

Receiving the following error when DBCC run prior to the backing up the database. Once the error is generated maintenance halts. We would then manually run DBCC’s with the ALL_ERRORMSGS option and the error disappears.

Problem is occurring once a week.
Different tables each occurrence.
Same database – more than one database on the server sharing the same physical disks no problems with them.

We have asked the hardware team to run diagnostics and check all the firmware and drivers. They are very reluctant because there are no errors found in the event logs and HP integrated log viewer.

We have asked the SAN team to look for any issues, they replied with no errors found, i.e. HBA, power path logs, fabric, etc…
Any guidance would be appreciated. I also plan on running SQLIOSim to hammer the server.

When you run the DBCC, have you got any of the repair options turned on?

REPAIR_ALLOW_DATA_LOSS | REPAIR_FAST | REPAIR_REBUILD

If so, this may be why you are not seeing an error afterwards.
