Abstract
A method for managing volumes in a scratch pool of a virtual tape system is disclosed. In one embodiment, such a method provides a scratch pool containing volumes for use in a virtual tape system. The method further enables a user to predefine an external pool of volumes residing outside of the scratch pool. This external pool may be hidden to a host system accessing the virtual tape system. The method monitors current and/or past usage of the volumes in the scratch pool and, based on the usage, predicts a future need for volumes in the scratch pool. The method automatically moves volumes between the external pool and the scratch pool in accordance with the future need. A corresponding system and computer program product are also disclosed.
