Global Phased mode is used when you are reasonably certain that Control-M/Tape will operate in the same way as the existing tape management system. This mode enables both Control-M/Tape and the existing tape management system to be fully operational simultaneously. The objective of Global Phased mode is to check the execution of Control-M/Tape in the production environment.
In this mode, Control-M/Tape and the existing tape management system each rely on their own media management decisions. These decisions must be the same. This is usually not a problem since Global Phased mode is used only after the Control-M/Tape Media Database and existing tape management system database have been synchronized (while Control-M/Tape was in Global Test mode).
During Global Phased mode, extended media management, such as automated tape library utilization, can be tested and "phased in" gradually. Procedures to be performed at the beginning of the working day and tape initialization requirements can also be implemented while in Global Phased mode.
Optionally, you can allow Control-M/Tape to operate in production mode for selected libraries while the other tape management system controls and manages media processing for all other libraries.
