Abstract

See full text

A mechanism is provided for improving the average response time of a tape library. Prior to receiving a next access request for data from one of a set of tape mediums, a determination is made as to whether a number of tape drives that are unoccupied is less than a predetermined minimum open tape drive threshold (N). Responsive to the number of tape drives that are unoccupied being less than the predetermined minimum open tape drive threshold (N), a least recently used idle tape medium is unmounted and unloaded from an associated tape drive.
