  • Patent number: 10394573
    Abstract: A method of a storage area network (SAN) includes storing and communicating data received from a server at a host bus adapter via a bus controller of the adapter. In a case where the data is associated with an address corresponding to a default boot logical unit (LUN) of a non-volatile memory (NVM) of the adapter, the data is stored in the NVM. In a case where the data is not associated with an address corresponding to a boot LUN of the NVM, the data is communicated over the SAN. During power up of the adapter, in a case where it is determined that the NVM includes an image of an operating system, the adapter uses the bus controller to provide the server with information to select the NVM as a boot LUN for booting the operating system.

    Abstract: An approach to synchronization of logical copy relationships on a local site with those on a remote site that is a mirror. A withdraw command is received on the local site for logical copy relationships between local source tracks and local target tracks. The withdraw command is executed and sent to a remote site buffer, from which it will be transferred to the remote site. Change indicators are set for the at least one local track in the affected logical copy relationships. If the withdraw command is lost from the remote site buffer, the remote site buffer will be rebuilt using the change indicators. By setting change indicators for local tracks in a withdrawn logical copy relationship (even if the data in local tracks hasn't changed), the remote counterparts to these tracks on the remote site will be rewritten, resulting in withdrawal of the logical copy relationship there even if the withdrawal command was never sent to the remote site.

  • Patent number: 8667323
    Abstract: Processing for file system volume error detection and processing for resultant error correction are separated to support system availability and user satisfaction. File system volumes for storing data structures are proactively scanned while the volumes remain online to search for errors or corruptions thereon. Found errors are scheduled to be corrected, i.e., spot corrected, dependent on the severity of the identified errors, error correction scheduling and/or at the determination of a file system administrator and/or user, to assist in maintaining minimal user and file system impact. When spot correction is initialized, one file system volume at a time is taken offline for correction. Spot correction verifies prior logged corruptions for the offline volume, and if independently verified, attempts to correct the prior noted corruptions. Volumes are retained offline only for the time necessary to verify and attempt to correct prior noted volume corruptions.

  • Patent number: 8656218
    Abstract: Performing data management operations on replicated data in a computer network. Log entries are generated for data management operations of an application executing on a source system. Consistency point entries are used to indicate a time of a known good, or recoverable, state of the application. A destination system is configured to process a copy of the log and consistency point entries to replicate data in a replication volume, the replicated data being a copy of the application data on the source system. When the replicated data represents a known good state of the application, as determined by the consistency point entries, the destination system(s) may perform a storage operation (e.g., snapshot, backup) to copy the replicated data and to logically associate the copied data with a time information (e.g., time stamp) indicative of the source system time when the application was in the known good state.

  • Patent number: 8621276
    Abstract: Perceived corruptions encountered on file system volumes, and which cannot be initially remedied online, are processed to verify whether they are true, existing volume data structure corruptions or, alternatively, false positives. Upon the verification of one or more of a volume's corruptions, error scanning is performed to check for, and attempt to remedy online, all the existing corruptions on the volume. Subsequent to error scanning processing, if one or more verified corruptions continue to exist on a file system volume, at file system boot up time spot corruption correction is performed to attempt to remedy the existing, verified corruptions on the volume. Spot corruption correction is performed to attempt to correct verified data structure corruptions on a volume of the file system while the volume is maintained offline for the time necessary to attempt to correct its prior identified corruptions.

  • Patent number: 8621267
    Abstract: The embodiments described herein generally relate to methods and systems for using an extended patching procedure for correction or repair of logical data portions, pages, or sectors of a computer data storage device. The extended patching procedure targets for repair not only the page(s) appearing to be defective or unusable based on a failed read operation for a data transfer request, but also additional pages. Determining the additional pages to include for automatic patching is based on: statistical distribution analyzes to include pages within the physical or logical vicinity of the original page, information about the underlying storage device technology or Input/Output (I/O) subsystem, and/or historical data about error conditions for areas related to the original page. Preemptively patching pages based on extended page lists improves system performance by reducing the total number of costly repair processes and by avoiding situations involving correction actions that fail to resolve.

  • Patent number: 8607099
    Abstract: Data structure errors, or corruptions, identified during, e.g., normal computing device system processing, file system processing or user access processing, are verified prior to the file system identifying the error for offline correction or notifying the user or system administrator a data structure error exists. Identified data structure corruptions are verified while the file system volumes are maintained online and otherwise accessible to other processing tasks and user access. Verified data structure corruptions are logged for further corrective processing. Data structure corruptions that cannot be verified, i.e., false positives, are not further processed and are not identified to file system administrators or users as corruptions, freeing the file system to concentrate on normal processing and true, verifiable errors.
