Figure 7 summarizes the relationships among the physical device environment, TSM storage and policy objects, and clients. The numbers in the following list correspond to the numbers in the figure.
Storage pools are mapped to device classes, which represent devices. The storage pool contains volumes as indicated by the device type associated with the device class. For example, a storage pool that is mapped to a device class with a device type of 3590 contains only 3590 tapes.
All devices require a device class that specifies at least a device type. Tape devices also require a library and drive for management of media, including the mounting of that media.
