Appendix E. Tape Processing Considerations

This chapter contains Product-sensitive Programming Interface and Associated Guidance Information.

This chapter provides information about setting Tivoli Storage Manager to use scratch tapes from the scratch pool controlled by your tape management system. Tape management systems vary, but you should use the same procedure for all:

  1. Define Tivoli Storage Manager to the tape management system as an external data manager, if applicable.

  2. Specify to the tape management system that a TSM volume must be permanently retained.

  3. Set up tape installation-wide exits

Here is a typical scenario when TSM requires a new scratch volume and requests a private mount:

  1. The tape management system can then give TSM a volume from the scratch pool. However, in most installations, the operator selects the scratch volume from a list provided by the tape management system.

  2. The tape management system verifies that the volume mounted is a scratch volume.

  3. Tivoli Storage Manager uses the volser of this tape to define the volume to the storage pool.

  4. The tape label is rewritten with the expiration date from the device class (if specified) and the data set name.

  5. When the tape volume becomes empty, usually due to reclamation, it is deleted from TSM. During the deletion process, the tape deletion exit is called and notifies the tape management system that it can return the tape to the scratch pool.
