Attorney, Agent or FirmInternational ClassesG06F 012/06G06F 012/08 AbstractVirtual data storage cartridges are created on a data storage subsystem to/from which volume writes and reads are directed. When a number of data volumes have been written, the controller may migrate them to the tape drive, a much faster process than writing directly to tape and enabling multiple logical volumes to be written to a single physical tape. With the present invention, virtual scratch cartridges are virtually premounted in a virtual drive loader while the virtual drive is accessing another virtual cartridge. When the host calls for a new scratch cartridge, it can be mounted in the virtual drive almost immediately, having already been virtually pre-loaded. | |
