Abstract: A method and apparatus to recover a construct definition associated with a logical volume in a virtual tape server (VTS) system following a disaster situation involving a library manager database. The method and apparatus re-establish the association between a logical volume or data file or block and a construct definition or volume attribute that assigns certain actions that may be taken on the logical volumes. Such actions and constructs may be defined by a client processor or by the VTS system in order to provide quality storage media management. The constructs may be uploaded to or reconstructed within the library manager database in combination with the host or virtual tape server and consequently made available to the system. In particular, the method and apparatus are configured to recover one or more of a storage group construct, a management class construct, a storage class construct, and a data class construct associated with a logical volume within a VTS system.

The check information may include a cyclic redundancy check (CRC), a logical block address (LBA), a longitudinal redundancy check (LRC), state information, a sequence number, or other information to identify data state, misplacement, or corruption. The check information, instead of being appended to the data within the data sector, may be stored in an independent check sector. The check information corresponding to multiple data sectors may also be aggregated and stored in a single check sector. The process or apparatus may be incorporated in a storage system controller, a RAID controller, a software SCSI stack in a computer, an operating system, a storage device driver, or another appropriate application that interfaces with standard and commodity storage system components.

Abstract: A recording head to simultaneously read or write data to and from a plurality of tracks on magnetic tape, while compensating for shrinkage or expansion caused by moisture, temperature, creep caused by tension in the tape, creep caused by dimensional instability of the tape, as well as other causes. A recording head in accordance with the invention includes a leading module and a trailing module. In order to accommodate fluctuation in tape dimensions due to expansion or shrinkage, the leading and trailing modules may be offset with respect to one another. By offsetting one module with respect to the other, selected read and write elements from one module may more closely align with certain tracks of an expanded or shrunk tape, while other read and write elements from the other module may more closely align with other tracks on the tape.

Abstract: A method and system for collecting and reviewing data related to web services receives service criteria from a service requester, selects candidate services that match the service criteria, invokes the selected candidate services, and aggregates results provided by the candidate services. In conjunction with aggregating results, the method and system builds service result objects conforming to a composite schema constructed from the various result schemas. To increase the utility of the aggregated results, metadata such as an invocation timestamp are also attached to each service result object. Result values are inspected and enumerated within a results table that may be used to determine which service result objects contain a particular result value.

Abstract: An interface definition that specifies the functionality of humanly accessed functions within a software program is parsed into statements by a parser in conjunction with a dictionary. The parsed statements are converted to formatted statements by a plurality of formatters resulting in expression of the interface definition in a plurality of selected formats. The selected formats comprise source code formats and various documentation formats. Files generated from source code formatters, such as “C++” formatters, are included in the software build process and facilitate restricting software development to the specified functionality. Changes to the interface definition are propagated to the selected formats resulting in software functionality that is consistent with the various forms of documentation such as on-line help and printed documentation.

Abstract: An apparatus, system, and process are disclosed for maintaining data in an electronic storage array during multiple, concurrent drive failures. A first drive failure is recognized and the storage system controller subsequently enters a first operating mode. The storage system controller then recognizes a second drive failure and enters a second operating mode, which is different from the first operating mode, in response to the second drive failure. The second operating mode allows the storage system controller and a recovery module to access the data of the second failed drive in a controlled manner in order to attempt to recover the data on the first failed drive. Also, a pinned data module may allow write data to be written to a pinned data drive, instead of a failed drive, while the storage system controller is operating in the second operating mode.
