SQL Server error code
SQL Server error 2534
SQL Server raises error 2534 at severity 16, which marks a problem with the query or data that you can correct.
Table error: page %S_PGID, whose header indicates that it is allocated to object ID %d, index ID %d, partition ID %I64d, alloc unit ID %I64d (type %.*ls), is allocated by another object.
| Msg | 2534 |

| Name | DBCC_PAGE_ALLOCATED_TO_OTHER_OBJECT |
| Severity | 16 |
| Group | 2000–2999 |
What it means
The header of the page contains the allocation unit ID, A_ID, but none of the Index Allocation Map (IAM) pages of that allocation unit allocates the page. Therefore, the header of the page contains the wrong allocation unit ID, and the page will have a matching MSSQLServer_2533 error that corresponds to the allocation unit ID to which the page is actually allocated.
