Tivoli Storage Manager supports a wide variety of devices and a current list is available at the Tivoli Storage Manager Web site:
TSM provides a Device Configuration wizard that allows administrators to perform drag-and-drop device configuration. In most cases, the wizard simplifies device configuration. However, a few devices cannot be configured with the wizard, for example 3494 libraries and SAN-atttached devices. Also in troubleshooting situations or in situations where administrators are using TSM commands to configure devices, administrators may need to understand underlying TSM technology.
See Overview of Tivoli Storage Manager Storage Objects for an overview of the technology, which includes policy, device classes, libraries, drives, storage pools, and storage pool volumes.
