Abstract

Disclosed are a method and processor external to an automated data storage library for partitioning the data storage library into multiple virtual libraries for access by a plurality of hosts, each host having a host port, the data storage library having a plurality of data storage drives, a plurality of storage slots, a library controller, the library controller identifying each of the data storage drives and the storage slots, a library port coupled to the library controller, and at least one accessing robot controlled by the library controller, comprising the steps of, at a node intermediate the library port and host ports, inquiring of the host ports to identify the number of host ports; inquiring, via the library port, of the library controller to determine the data storage drive identifiers and the total number of the storage slots; identifying by employing the data storage drive identifiers, the data storage drives associated with each host port; and sequentially creating virtual libraries, assigning to each virtual library at least one host port, the data storage drives identified as associated with the assigned host port, and a portion of the storage slots (s).
