Symbolic Name

DBCC3_IAM_PAGE_RANGE_IN_WRONG_FILEGROUP

Message Text

IAM page P_ID for object ID O_ID, index ID I_ID, partition ID PN_ID, alloc unit ID A_ID (type TYPE) controls pages in filegroup FG_ID1, that should be in filegroup FG_ID2.

The index allocation map (IAM) page P_ID in filegroup FG_ID1 incorrectly includes extents from filegroup FG_ID2. All extents for an IAM page should be in the same filegroup as the IAM page itself.

Look for Hardware Failure

Run hardware diagnostics and correct any problems. Also examine the Microsoft Windows system and application logs and the SQL Server error log to see whether the error occurred as the result of hardware failure. Fix any hardware-related problems that are contained in the logs.

If you have persistent data corruption problems, try to swap out different hardware components to isolate the problem. Check to make sure that the system does not have write-caching enabled on the disk controller. If you suspect write-caching to be the problem, contact your hardware vendor.

Finally, you might find it useful to switch to a new hardware system. This switch may include reformatting the disk drives and reinstalling the operating system.

Restore from Backup

If the problem is not hardware related and a known clean backup is available, restore the database from the backup.

Run DBCC CHECKDB

Not applicable. This error cannot be repaired. If you cannot restore the database from a backup, contact Microsoft Customer Service and Support (CSS).
