Abstract
A system, method, and apparatus are provided for copying a virtual volume to multiple physical volumes within a virtual tape system. The virtual tape system may include a virtual tape server (VTS), a library manager, and a plurality of tape drive units into which cartridges may be individually mounted. The virtual tape system stores virtual volumes, each of which represents a physical volume, although one or more virtual volumes are actually stored on a real physical volume. The library manager contains a volume database with a plurality of constructs and associated storage management actions. The constructs are received from a host computer connected to the VTS, but the storage management actions may be entered directly into the library manager, independently of the host. The library manager reads the management action associated with one or more constructs of a virtual volume and, along with the VTS, determines whether multiple physical copies of the virtual volume are to be made.
