Error 8906
Severity Level 16
Message Text
Page %S_PGID in database ID %d is allocated in the SGAM %S_PGID and PFS %S_PGID, but was not allocated in any IAM. PFS flags '%hs'.
Explanation
SQL Server has found an allocation error in the specified database.
Action
Either restore from a known clean backup or execute DBCC CHECKDB with the REPAIR_ALLOW_DATA_LOSS clause. For example:
DBCC CHECKDB('pubs', REPAIR_ALLOW_DATA_LOSS)
If the error involves an index page, use the REPAIR_REBUILD clause. If the error involves a data page, it may be necessary to use the REPAIR_ALLOW_DATA_LOSS clause. In the likely event that you cannot allow the loss of data, you will need to restore from a known clean backup. If the problem persists, contact your primary support provider. Have the output from DBCC CHECKDB available for review.
Important If executing DBCC CHECKDB with one of the repair clauses does not correct the index problem or if you are unsure what effect DBCC CHECKDB with a repair clause has on your data, contact your primary support provider.
If DBCC CHECKDB with the REPAIR_ALLOW_DATA_LOSS clause does not resolve the allocation error, contact your primary support provider.
