    摘要: Disclosed are a system, a method, and article of manufacture to provide for managing removable storage media that is identified by a persistent worldwide name. SAN storage management is enhanced by preserving the persistent worldwide names assigned to removable storage media when it is necessary to replace the removable storage media. Exemplary embodiments include determining that a first removable storage media identified by a persistent worldwide name needs to be replaced, creating a copy of the data from the first removable storage media and assigning the persistent worldwide name to the second removable storage media.

    摘要: A method to sequentially deduplicate data, wherein the method receives a plurality of computer files, wherein each of the plurality of computer files comprises a label comprising a file name, a file type, a version number, and file size, and stores that plurality of computer files in a deduplication queue. The method then identifies a subset of the plurality of computer files, wherein each file of the subset comprises the same file name but a different version number, and wherein the subset comprises a maximum count of version numbers, and wherein the subset comprises a portion of the plurality of computer files. The method deduplicates the subset using a hash algorithm, and removes the subset from said deduplication queue.

    摘要: An approach for automatically sharing a tape drive in a heterogeneous computing environment that includes a first computer and second computer is presented. The first computer receives a message that includes a shared tape drive identifier, a source port identifier of the second computer, and a reservation status change for the tape drive. Based on the tape drive identifier, the first computer determines that the tape drive is connected to the first computer. The source port identifier is determined to not identify any host bus adapter installed in the first computer. In response to the first computer determining that the reservation status change indicates a reservation or a release of the tape drive for the second computer, the first computer sets the tape drive offline or online, respectively, in an application executing in the first computer.

    摘要: A storage management application determines that a source virtual tape requires reclamation, identifies all block addresses for active data of a source virtual tape and sorts the block addresses in an ascending order, identifies a target virtual tape which has sufficient free capacity to store the active data of said source virtual tape and the last written block address on said target virtual tape, and sends a command to the VTL-system instructing it to perform reclamation including information about said source and said target virtual tape, the sorted list of block addresses denoting active data on the source virtual tape and the starting block address on the target virtual tape. The reclamation logic references the active data host blocks of said source volume to said target virtual tape starting at said starting block address by just updating the host block to disk block mapping table.

    摘要: A method for deduplicating and managing data blocks within a file system includes adding a deduplication identifier to each pointer pointing to a data block to indicate whether the data block is deduplicated, detecting duplicate data blocks, determining whether one of the duplicate data blocks has been deduplicated, when detected, determining that one duplicate data block is a master copy when it is determined that one duplicate data block has been deduplicated, selecting one of the duplicate data blocks to be a master copy when it is determined that the duplicate data blocks have not been deduplicated, and setting the deduplication identifier of the selected duplicate data block to indicate deduplication, and determining that the other duplicate data block is a new duplicate data block and setting the deduplication identifier of the other duplicate data block to indicate deduplication and directing the respective pointer to the master copy.

    摘要: The present invention provides a method and system for performing file recovery in a computer system coupled to a storage subsystem, wherein a data scrubbing process analyzes said storage subsystem for potential or existing storage errors. The method includes: receiving a report from said data scrubbing process describing said errors, including logical block addresses (LBAs) of storage locations containing errors; interacting with a file system created on logical unit numbers (LUN) provided by said storage subsystem in order to identify file information pertaining to the erroneous LBAs; moving the file pertaining to said erroneous LBAs to a different storage location; updating pointers to said file; in case of an unrecoverable, accessing a backup copy of said file from a backup location; if a predetermined degree of error severity is exceeded, creating an additional copy of said file; and updating the pointers to said file managed by the file system, respectively.
