Overview

Control-M/Tape can have a major impact on the management and control of all your removable media. Control-M/Tape can apply automated media management to every component of your operations environment and drastically reduce the need for human intervention and consequent errors.

Control-M/Tape is gradually phased through operation in various modes, culminating in a fully operational Control-M/Tape and termination of your existing tape management system. Gradual transition from the existing tape management system to Control-M/Tape through the various Control-M/Tape operation modes is described in this guide.

Note: Advanced features and customization should be added only when basic Control-M/Tape functioning has been tested and Control-M/Tape is already operating in production mode.

Control-M/Tape operation modes play a central role in migration to Control-M/Tape. It is therefore important to understand the differences between the various modes and the role they play in Control-M/Tape implementation.

Control-M/Tape operation mode is specified using the MODET parameter in the CTTPARM member as shown in the following screen:

Each time Control-M/Tape mode is modified, tape processing must be halted and tape management data should be reconverted. This is because the processing of tapes during data conversion can result in discrepancies between the existing tape management system database and the Control-M/Tape Media Database.

Note: Conversion of tape management data is described briefly in this chapter. For a more detailed explanation of this process, see the Control-M/Tape Conversion Guide.
