Overview Volume management provides a way to partition disk storage space into three logical entities: volumes, volume sets, and volume classes. The volume itself is the initial entity; it is the basic building block in volume management. The most common operating entity, however, is the volume set, which comprises one or more volumes. The final entity is the volume class, which contains one or more related volumes. A volume class is a subset of the volume set. Since MPE XL differentiates between media and devices, volume management controls disk media, or volumes, while device management controls devices. The media contain files and information such as file labels and directories which control access to files. Volume class and volume configuration information reside on the volume set. They are on the media, not in the system configuration. The MPE XL volume management utility, VOLUTIL, provides routines for initializing volumes as well as for performing maintenance and inquiry functions.
