Test mode

Control-M/Tape works in parallel to other tape management systems at the site.

Information is recorded in the Media Database, but Control-M/Tape does not intervene in any way (for example, prompts are not issued, unexpired data sets are not protected, and mount messages are not modified). Default.

Phased mode

Control-M/Tape works in parallel with other tape management systems at the site. Both products control and protect media at the site.
