Overview

Inconsistencies in the Media Database may result from conversion of corrupted data in the existing tape management system’s database, or from a system crash, utility abend, and so on.

To check the integrity of the Media Database, run Control-M/Tape utility CTTIDB. This utility produces warning messages if inconsistencies are detected in the Media Database. Once Control-M/Tape is operational at your site, the CTTIDB utility is normally run as part of the Control-M/Tape New Day procedure to verify Media Database integrity.

Examples of inconsistencies are:

• errors in the links that connect multi-volume data sets (normally a result of conversion)
• active volumes that do not contain data sets
• scratch volumes that contain active data sets
• inconsistencies in the Media Database can be corrected through the Control-M/Tape Inquire/Update screen (TI), or through Media Database update the CTTMUP utility
