テーブル エラー: IAM ページはオブジェクトの IAM チェーンにリンクされています

Microsoft.SQLServer.2005.Table_error__IAM_page_is_linked_in_the_IAM_chain_for_object_1_5_Rule (Rule)

Knowledge Base article:

原因

インデックスのすべての IAM ページのインデックス ID が同じになっている必要があります。この場合、インデックス I_ID2 の IAM チェーン内にリンクされた IAM ページのいずれかのインデックス ID が I_ID1 になっています。このエラーの場合に考えられる 3 つの状態があります。それらはすべて同じことを意味しますが、検出が行われる場所が異なります。

解決方法

ハードウェア障害

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.

修復によって両方のインデックスの IAM チェーンが修正されるため、どちらも正しくなります。IAM ページ <I>P_ID1<I> は、どちらかまたは両方のチェーンから削除されます。

CAUTION: This repair may cause data loss.

If running DBCC CHECKDB with one of the repair clauses does not correct the problem, contact your primary support provider.
