摘要： A method and apparatus for monitoring update activity, particularly in the form of write requests, to a data storage facility, over at least one cycle to identify any write operation or update that occurs to that data storage facility on a track-by-track basis. At the end of each cycle a list of changed tracks is stored in a data set. After information has been accumulated by a collector application, a reporter application manipulates the data to obtain information concerning the track changes and to estimate communication path requirements.

摘要： A method and apparatus for enhancing data recovery in data processing systems in which applications span multiple logical devices. A data processing system includes multiple standard devices for storing data and corresponding BCV devices for, in one mode, operating as mirrors of those standard devices. If certain of those BCV devices are associated with the same data set, a CONSISTENT SPLIT operation controls the way in which each of these BCV devices is detached from its corresponding standard device and made available to another application. Each command to an application for controlling the BCV devices is translated into one or more request data structures that identify the BCV devices as being involved in a consistent split operation and that establishes a system lock out for those particular devices during which those devices are split from their respective devices in a consistent manner.

摘要： A system and method for providing on-line, real-time, transparent data migration from an existing storage device to a replacement storage device. The existing and replacement storage devices are connected as a composite storage device that is coupled to a host, network or other data processing system. The replacement storage device includes a table which identifies data elements that have migrated to the replacement storage device. When a host system makes a data transfer request for one or more data elements, the replacement storage device determines whether the data elements have been migrated. If the data elements have migrated, the replacement storage device responds to the data transfer request independently of any interaction with the existing storage device. If the data elements have not migrated, the replacement storage device migrates the requested data elements and then responds to the data request and updates the data element map or table. When not busy servicing other requests, the replacement storage device operates in a background mode to migrate data elements so the data migration can occur concurrently with and transparently to system operations.

摘要： A method and apparatus for emulating a magnetic tape storage device with a conventional, unmodified magnetic disk storage device. I/O output requests for the emulated magnetic tape storage device are intercepted to determine whether they involve a virtual tape resource that comprises a magnetic disk storage device. Tape requests to such a resource are converted into one or more conventional magnetic disk storage requests to effect an analogous operation.

摘要： A method for operating a magnetic disk storage device in read/write and read-only modes. A control program in a system cache memory receives write requests for transferring data to a logical volume. The control program determines whether the write request is directed to a track that is in a read/write or read-only operating mode. Only requests to tracks having a read/write operating mode are enabled to continue. A system administrator or user controls the operating modes for each track in the disk operating system.

摘要： Transferring storage device functionality includes providing a device coupled to the storage device, where the device is separate from the storage device, having the device handle I/O requests between an application and the storage device, and, in response to the application issuing an I/O request, having the device determine if the request corresponds to functionality being transferred and, if so, having the device provide the functionality. The device may be a host computer. The application may run on the host computer. A driver on the host computer may provide the functionality. The functionality may include read only functionality, data compression, data encryption, mirroring, and/or status reporting.

摘要： Managing data on a storage device includes intercepting unencrypted data to be stored on the storage device, where intercepting unencrypted data is transparent to an application storing the data on the storage device and encrypting the data prior to storage on the storage device. The storage device may include a tape drive and/or a disk drive. Managing data on a storage device may also include migrating data from a first storage location to a second storage location. The first storage location may be the same as the second storage location or the first storage location may be different from the second storage location. The unencrypted data may be intercepted during migration. Managing data on a storage device may also include decrypting data read from the storage device.

摘要： Accessing data includes a host establishing a relationship between a first storage area of a first type containing data and a second storage area of a second type containing pointers to data provided in storage areas of the first type, where the storage areas are provided in a storage device coupled to the host. In response to the host writing data to a particular section of the first storage area after establishing the relationship, the particular section is copied from the first storage area to a third storage area of the first type prior to the write operation being executed. A corresponding pointer of the second storage area is adjusted to point to the third storage area.
