  • Publication number: 20060174071
    Abstract: Embodiments of the present invention provide a method and system for handling status commands directed to a partitioned media library. A controller (e.g., storage router or other device) that controls access to the physical media library can receive a status command and determine whether it should respond to the status command without passing the command to the media changer of the physical media library. If the controller should respond, the controller can construct a response and send it to the issuing host application. Otherwise the controller can pass the command to the media changer of the physical media library.

  • Publication number: 20060174088
    Abstract: According to one embodiment of the present invention, a controller that partitions a media library for multiple host applications can, for each partition, assign a base element address for an element type and associate physical element addresses for elements of an element type with an index value. For a partition, the logical element address corresponding to a physical element address for an element can be determined by adding the index number associated with the physical element address to the base element address for that element type. The physical element address corresponding to a logical element address for an element can be determined by subtracting the base element address for the element type from the logical element address for the element. The result of subtracting the base element address from the logical element address is an index value for which the associated physical element address can be found.

  • Publication number: 20060170238
    Abstract: One embodiment of the present invention includes a method for handling status commands direct to a partitioned media library that comprises establishing a set of initial logical element addresses for a set of physical element addresses with each initial logical element address corresponding to a physical element address of an element assigned to a library partition, assigning a set of new logical element addresses for the set of physical element addresses in response to a command from a host application (e.g., a MODE SELECT command) and determining a corresponding physical address for a received element address based on the set of new logical element addresses.

  • Publication number: 20060080507
    Abstract: Embodiments of the present invention provide a system and method for handling unit attentions. According to one embodiment of the present invention, a copy manager can receive an extended copy command and can issue a unit attention clearing command, such as the test unit ready command, to the source and destination devices listed in the extended copy command. The copy manager can further issue read commands to the source device and write commands to the destination device to copy data from the source device to the destination device according to the extended copy command.
