Abstract: Disclosed is a method, system, program, and data structures for mapping logical units, such as logical unit numbers (LUNs), to a storage space comprised of at least one array of storage units, e.g., hard disk drives. Configuration information stored in one array indicating a first mapping of logical units to storage locations in the array is read. A second mapping of logical units to storage locations in multiple arrays is generated using the configuration information read from the array. Each logical unit is assigned to only one of the arrays.

Abstract: Disclosed is a method, system, program, and data structures for maintaining electronic data at a point-in-time. A first data structure indicates point-in-time data at one of a first storage location and a corresponding second storage location. A second data structure indicates point-in-time data at one of a first storage location and corresponding second storage location. A first relationship data structure indicates a relationship between the first storage location and corresponding second storage location and a second relationship data structure indicates a relationship between the first storage location and second storage location. A request to process the first storage location is processed by processing the first relationship data structure to determine the corresponding second storage location for the first storage location and processing the first data structure to determine whether data at the first storage location was transferred to the second storage location.

Abstract: Disclosed is a method, system, and program for accessing an object in a network providing communication among multiple network devices and a namespace server including a namespace comprising one network address, e.g., IP address, for each network device in the system. The network device retrieves the namespace from the namespace server over the network and maintains the retrieved namespace as a local namespace at the network device. The network device may then determine the network address of a target network device to use to send a request to the network address of the target network device.

Abstract: Disclosed is a method, system, program, and data structure for transforming at least one column in a database input table. An input data table has multiple columns and rows. A determination is made of multiple data column names and multiple pivot columns in the input table. A row is generated in an output table for each data column name, having one data column name field including one data column name and at least one pivot column field including the value in one pivot column field in the input table, wherein each of the rows in the output table for each data column name has different values in at least one of the data column name field and pivot column field.

Abstract: A variably positionable electrical connector provides a direct interface for a disk drive or other electrical device to a printed circuit board (PCB), backplane or motherboard of a computer system. The connector has a base (which may comprise a PCB or backplane) and a housing that slides relative to the base to allow the housing to be positioned according to the spacing between the electrical device's power and signal connectors. The housing includes multiple electrical contacts that receive or engage corresponding contacts of the device. Conductors that are electrically coupled to the computer system extend from the base and include portions that are aligned substantially parallel to a direction in which the housing can slide. The housing contacts slidably engage the parallel portions of the conductors and, as the housing is moved, the housing contacts slidably maintain electrical contact with the conductors.

Abstract: Disclosed is a method, system, program, and data structure for selecting a path to one of at least two controllers. Each controller is capable of providing access to storage areas, such as Logical Unit Numbers (LUNs). Path information is received from the controllers indicating a preferred controller to use to access each storage area. An input/output (I/O) command directed to a target storage area is processed and the I/O command is directed to the controller indicated in the path information as the preferred controller for the target storage area. The controller receiving the I/O command executes the I/O command against the target storage area. The path information to the storage controllers providing access to the storage areas is encoded with information designating one controller as the preferred controller and another as a non-preferred controller. The encoded path information is returned to a requesting computer.

Abstract: Disclosed is a set of tools or program instructions, an installation program, and a system that operates a drive in a platform independent manner. A drive object represents a single drive mounted by an operating system and contains fields providing information including drive name, block size, free space, type, format long file name support, and space needed by the files to be installed on that drive. During the installation process, each drive is processed to ensure that the drive has sufficient free space for the files to be installed.

Abstract: Disclosed is a system, method, and program for accessing an application program, such as a transaction manager. A request for a file is received. The request includes a pathname and the pathname includes at least one directory name and the file name. The pathname is processed by a file system to determine whether the request is for a file on a storage device or an operation for the application program to perform. The file request is processed to generate a control message for the application program after determining that the request is not for a file on the storage device. The control message is then passed to the application program to cause the application program to perform an operation.

Abstract: Disclosed is a system, method, and program for testing appliances. The appliance includes an embedded processor and an appliance network address to communicate with remote systems over a network. A first server program having a first network address, such as an HTTP server program, receives a test request indicating a test to perform and an appliance to test. A second server program, such as a Java servlet, having a second network address is loaded and transmits information on the test request to the appliance network address indicated in the test request. A third server program having a third network address, such as a Java servlet, is loaded to execute within the appliance embedded processor in response to receiving information on the test request. The second server program transmits at least one test command to the third network address.

Abstract: Provided is a method, system, and program for releasing storage space in a first and second storage devices. Updates to the first storage device are copied to the second storage device to provide secondary storage for the updates. A first and second tables map data sets to addresses in the first and second storage devices, respectively. A first command is detected to invalidate data sets in the first table. The addresses in the first table comprise virtual addresses, and a third table provides a mapping of the virtual addresses to physical storage locations in the first storage device. A second command is generated to update the second table to invalidate the data sets in the second storage device invalidated in the first table by the first command. A third command is detected to invalidate the virtual addresses in the third table used by the data sets invalidated in the first table to free the physical storage locations in the first storage device pointed to by the invalidated virtual addresses.

Abstract: The present invention concerns a method, apparatus, and article of manufacture for managing print files associated with a job ticket describing a plurality of print files included in a print job. The print files are stored in a library within a server. When space usage in the library has exceeded a predetermined limit, print files are migrated from the library to a backup unit. For each file migrated from the first storage device to the second storage device, a stub file is generated which includes information on the migrated file. A computer is used to select a print file to include in the print job described in the job ticket. If the print file selected is stored in the backup unit and a stub file is stored in the library, then the server will access the stub file upon selection of the print file. The stub file in the library is replaced with the print file in the backup unit when the stub file is accessed.
