Abstract: Provided is a method, system, and program implemented by a server for controlling and providing access to a file to at least one remote computer over a network. The server maintains metadata about files. The files are maintained at remote storage locations. The server receives a request from the remote computer for a filename of a requested file over the network. The server determines from the metadata one remote storage location address associated with the filename where the requested file is located. The server then updates the metadata for the requested file and sends the storage location address to the remote computer.

Abstract: Disclosed is a method, system, program, and data structure for providing a shadow copy of data storage areas in a primary site to data storage areas in a secondary site. A definition is made of storage areas in the primary site having data to be shadowed and corresponding storage areas in the secondary site to shadow data at the storage areas in the primary site. A shadow pair comprises one primary storage area and one secondary storage area that shadows data for the primary storage area in the pair. A standard data transfer interface protocol command, such as a SCSI or Fibre Channel command, is used to configure status storage areas in the secondary site to provide status information and data for each primary and secondary storage area. A write command in the standard data transfer interface protocol is then used to write status information to the status storage areas indicating status of the shadowed data at the secondary storage areas in the pairs.

Abstract: Provided is a method, system, and program for initializing a storage device comprising multiple storage units through a storage controller. A request is received to initialize a storage space that spans the storage units. A determination is made of a layout of sets of sequential data blocks of the storage space on the storage units, wherein sets of sequential data blocks are written across the storage units. For each set of sequential data blocks, a determination is made of a block address in each storage unit where a first data block in the set of sequential data blocks will be written. A write command is generated for each of the storage units, wherein each write command indicates the determined block address for the storage unit and a block number. The write command is transmitted with one block of initialization data to the storage unit.

Abstract: Provided is a method, system, and program for configuring an attached storage device through a storage adaptor. The storage adaptor includes an initialization routine to generate initialization data to write to the storage device when adding storage space in the storage device to a system. A request is received to add storage space to the system. A command is transmitted to the storage adaptor capable of inhibiting the storage adaptor from performing the initialization routine. Initialization data is generated for the storage space and transmitted to the storage adaptor to write to the storage space to initialize the storage space.

Abstract: Provided are a system, method, program, and data structure for processing a request for data in a first format that is superimposed on blocks of data stored in a second format in a storage device. A data structure for a storage unit in the first format including the requested data is accessed. There is one data structure for each storage unit in the first format being accessed. Further, at least one cache page storing blocks of data in the second format is needed to store one storage unit in the first format. A determination is made of one or more storage blocks in the second format that include the requested data. A determination is also made as to whether the storage unit data structure includes a pointer to a control block for a cache page that would include the determined storage blocks in the second format.

Abstract: Provided is a method, system, and program for superimposing a data record in a first data format onto a storage space in a second data format. A plurality of control blocks are built in memory indicating operations to perform to transfer components of the data record in the first data format to locations in memory in the second data format. A data transfer device is signaled to access the control blocks built in the memory. The data transfer device accesses the control blocks in the memory and then transfers components of the data record in the first data format to the memory to be stored in the second data format according to the operations indicated in the control blocks.

Abstract: Disclosed is a method, system, program, and data structure for defining paths for a computer to use to send commands to execute with respect to storage regions in a storage device that are accessible through at least two controllers. For each storage region, one controller is designated as a preferred controller and another as a non-preferred controller. The computer initially sends a command to be executed with respect to a target storage region to the preferred controller for the target storage region and sends the command to the non-preferred controller for the target storage region if the preferred controller cannot execute the command against the target storage region. In response to the non-preferred controller receiving at least one command for the target storage region, the designation is modified to make a current preferred controller the non-preferred controller for the target storage region and a current non-preferred controller the preferred controller for the target storage region.

Abstract: A method and apparatus for processing jobs on an enterprise-wide computer system. The computer system uses a portal architecture to allow a user to view a wide variety of content retrieved from a variety of different computer systems. The computer system is configured such that a plurality of users can access the system at the same time through a computer network such as the Internet. Users may access the computer system by using a standardized browser program, thus simplifying the user interface. The computer system may also be connected to one or more back-end databases that correspond to the different computer systems within the enterprise. The computer system is configured to run predefined jobs to process data. These jobs can perform a variety of tasks such as retrieving data from a back-end database, preparing a report based upon retrieved data, processing data already resident within the portal system, or notifying a user when a particular condition occurs within the portal system.

Abstract: A system for providing multiple hosts with concurrent access to cached data by selectively generating, maintaining, modifying, and consolidating multiple versions of data items in cache memory to efficiently accommodate data access requests by the hosts. Data associated with a logical track is represented in cache by a number of cache track image parts. Each part represents one or more records in cache, where multiple parts may exist in cache for the same logical track. The provision of multiple parts supports concurrent access by multiple operations or "processes" to data associated with a track. Namely, each part is given a "status" selected from a predetermined catalog of statuses; the assigned status thus establishes the permissible manner of accessing that part. Depending upon a part's status, the part may be used by one process (e.g. Read) or by multiple processes concurrently (e.g. Read and Destage). Other part statuses dedicate a part to a single process (e.g. Write).
