The first phase of a DBCC CHECKDB is to do primitive checks on the data pages of critical system tables. If any errors are found, they cannot be repaired, so the DBCC CHECKDB terminates immediately.
This error means that the next page pointer of page P_ID1 points to page P_ID2, but the prev page pointer of page P_ID2 points to page P_ID3—not back to page P_ID1 as it should.
HARDWARE FAILURE
Run hardware diagnostics and correct any problems. Also examine the Microsoft® Windows NT® system and application logs and the SQL Server™ error log to see if the error occurred as the result of hardware failure. Fix any hardware-related problems.
If you have persistent data corruption problems, try to swap out different hardware components to isolate the problem. Check to ensure that your system does not have write caching enabled on the disk controller. If you suspect this to be the case, contact your hardware vendor.
Finally, you might find it beneficial to switch to a completely new hardware system, including 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.
DBCC CHECKDB
If no clean backup is available, execute DBCC CHECKDB without a repair clause to determine the extent of the corruption. DBCC CHECKDB will recommend a repair clause to use. Then, execute DBCC CHECKDB with the appropriate repair clause to repair the corruption.
CAUTION: If you are unsure what effect DBCC CHECKDB with a repair clause has on your data, contact your primary support provider before executing this statement.
If running DBCC CHECKDB with one of the repair clauses does not correct the problem, contact your primary support provider.
This error cannot be repaired automatically.
