Logical integrity errors are corrected by updating the data records and/or index records that are in error. For details, see the chapter about verifying media database integrity in the Control‑M/Tape Implementation Guide.
Errors involving data records must be corrected one at a time, using the CTTMUP utility. After fixing each error, it is recommended that you rerun the CTTIDB utility, because fixing one error often eliminates other errors. This can be done automatically by specifying CHECK=YES in the TYPERUN statement of the CTTMUP utility. The output of the CTTIDB utility after it is rerun indicates the integrity errors that remain.
The CTTMUP utility can also be used to fix most index related problems by rebuilding the indexes for a volume, a dataset, or a group of volumes and datasets.
If a large number of index errors are found in the Media Database, consider fixing these errors by rebuilding the index component using the CTTBIX utility.
Note: If you choose to rebuild the index of the Media Database, you must first halt all tape processing.
For a detailed description of the CTTIDB, CTTMUP and CTTBIX utilities, see the INCONTROL for z/OS Utilities Guide.
