  • Method and apparatus for implementing autonomous variation of media dismount time in a robotic media library
    Patent number: 6982847
    Abstract: A method, apparatus and computer program product are provided for implementing autonomous variation of media dismount time in a robotic media library. I/O requests to the robotic media library are monitored. Performance statistics are gathered for the I/O requests to the robotic media library. The gathered performance statistics are periodically checked to determine if a change is needed for the media dismount time. The gathered performance statistics include a media hit count of where a data storage medium (DSM) for an I/O request is in a robotic media drive, and a media near miss count where the DSM for the I/O request is in transit from the robotic media drive.

  • Method, article of manufacture and apparatus for copying information to a storage medium
    Patent number: 6779129
    Abstract: A method, apparatus and article of manufacture for copying information from a first storage medium to a second storage medium. A first storage medium of memory blocks is mapped into at least one data block and at least one directory block. Two passes of the first storage medium are then performed. In the first pass, each data block is copied from the first storage medium to the second storage medium. If a read error occurs while copying a data block, a location of the data block and a data file stored in the data block are identified to provide future error handling capability. In the second pass, each directory block is copied from the first storage medium to the second storage medium.
