Abstract: Methods for certifying data retained by a tape cartridge in a tape library are shown. Error rates that are encountered when the tape cartridge is being read by a tape drive can be accounted for without actually reading data for data content retrieval. A record of the error rate can be stored in a medium auxiliary memory device associated with the tape cartridge. An older record containing a formerly accounted for error rate of read errors when the tape cartridge was formerly read can be accessed and compared with the record presently assessed. If there is a difference between the presently found error rate and the formerly found error rate an action can be executed if the difference exceeds a predetermined threshold.

Abstract: A storage library is described that includes a shelf system adapted to support a number of tape cartridges. The storage library further includes a tape drive adapted to read and write data to and from tape cartridges. The storage library further possesses a temporary repository near the tape drive that is adapted to facilitate an exchange of a first tape cartridge intended to be loaded in the tape drive with a second tape cartridge ready to be removed from the tape drive with a single tape picker device.

Abstract: A robotic tape library which queues two or more move instructions is described. Generally, the robotic system receives a first move instruction which commands a first robot to move a first tape cartridge from a shelf to a first tape drive to be loaded therein. Though the first move has not actually taken place, the library replies to the host computer that the first tape drive has been loaded with the first tape cartridge, at least to an acceptable level of engagement, at which point, the first move instruction is queued. After receiving a second move instruction from the host to move a second tape cartridge from the shelf to a second tape drive, the library reorganizes and physically carries out the move instructions with potentially different hardware in a preferred order.

Abstract: A method for recovering data from a failed tape cartridge is presented. The reliability of a tape cartridge is assessed via the number of read errors encountered. If the number or read errors is excessive, the tape cartridge is deemed unreliable and the tape cartridge is restricted from storing anymore data. A search is performed to look for duplicate data and if found a copy of the duplicate data is stored to a replacement tape cartridge. The replacement tape cartridge assumes all identity of the original failed tape cartridge.

Abstract: A tape cartridge is described including tape storage medium maintaining stored encrypted data that can be unencrypted via an encryption key.

The tape cartridge further includes a threshold parameter stored in the medium auxiliary memory wherein the threshold parameter influences a moniker state control, the moniker state control comprises an on state and an off state wherein the off state disables the moniker from identifying the encryption key.

Abstract: A method for verifying a tape cartridge is presented. One method includes introducing a tape cartridge into a tape library wherein when introduced, the tape cartridge can then be loaded in a tape drive in an attempt to bring the tape cartridge to a functionally ready state with the tape drive. In loading the tape cartridge in the tape drive, the loading performance of the first tape cartridge can be assessed based on bringing the first tape cartridge to a functionally ready state. A record of the performance information can then be stored on a central data base and/or on a medium auxiliary memory device located in the tape cartridge.
