Abstract: A primary data mover monitors both consistency time and idle time in a system that performs continuous, asynchronous, extended remote copying between primary and remote processors, and manages both with accuracy and consistency. The primary data mover detects system activity levels and manages data accuracy for the extended remote copying in both active and idle systems.

Abstract: A method, apparatus, and article of manufacture for performing a point-in-time backup using multiple copy technologies includes steps of suspending execution of updates to the source data; determining what point-in-time backup technology is supported by the device by determining the device and extents of the source data; processing each of the extents as determined by the backup technology supported and copying the source data in point-in-time; and backing up copied entire source data to a target media. If the backup process fails, the method, apparatus, and article of manufacture provides a restart function.

Abstract: Disclosed is a system for backing up files in a distributed computing system. A file server maintains files in a shared name space. The file server provides a first backup client program and a second backup client program with access to the files in the shared name space. The first backup client program initiates a backup request to backup a requested file. A determination is made as to whether the requested file is maintained in a shared name space. The backup request is transmitted to the second backup client program upon determining that the requested file is maintained in the shared name space. The second backup client program transmits a message to the file server to provide the requested file. The file server transmits the requested file with the file server to the second backup client program. The second backup client program then transmits the requested file to a backup server program. The backup server program stores the requested file in a storage device.

Abstract: Disclosed is a system for indicating whether a group of at least one library element was accessed. The library elements are contained within a housing and are capable of holding storage cartridges. A controller is signaled when an access door of the housing is in an open position. An operator may access the library elements when the access door is in the open position. A motion detector directed toward the group of library elements is activated to detect whether at least one library element in the group was accessed. The motion detector signals the controller upon detecting that at least one library element in the group was accessed. The controller then indicates in a memory area that at least one of the library elements in the group was accessed after the controller is signaled that the access door is in the open position and that at least one library element in the group was accessed.

Abstract: Disclosed is a system to diagnose and handle errors in an automated hierarchical storage management system. A host system requests an access operation on a first file, such as a logical volume, in a first storage device, such as a magnetic hard disk drive. A server processes the host request to determine whether the first file is resident in the first storage device. The server initiates a recall of a second file, such as a physical volume, in a second storage device, such as tape cartridges, optical disks, etc., corresponding to the first file upon determining that the first file is not resident in the first storage device. The second file is then copied from the second storage device to the first file in the first storage device upon determining that the second file is accessible. The server further determines whether the recall of the second file has failed.

Abstract: Disclosed is a system for handling failures in a storage controller interfacing between a plurality of host systems and direct access storage devices (DASDs). The storage controller directs data from the host systems through a first and second data paths in the storage controller to a DASD. A first processor, first non-volatile memory unit (NVS), and a first cache are associated with the first data path and a second processor, a second NVS, and a second cache are associated with the second data path. A bridge provides communication between the first processor and the second NVS and the second processor and the first NVS. During normal operations prior to a failure in the storage controller, data directed to the first data path is written in the first cache and communicated with the first processor to the second NVS via the bridge for storage in the second NVS.

Abstract: The present invention discloses a method, apparatus, and article of manufacture for organizing files associated with a job ticket in a computer system linked to a storage device. The job ticket includes information on a document included in a print job, information on a plurality of files that are associated with the document, and location information indicating the location of the files. The user specifies a directory location in the storage device in which to copy the job ticket and related print job files. The files are accessed using the location information and copied, along with the job ticket, to the user specified directory location in the storage device. The invention may further include the step of modifying the location information to indicate that the files copied to the directory location are in a location relative to the location of the job ticket. The user may enter the directory location using a GUI on a computer.

Abstract: A system, method, and program for generating a color rendering dictionary file or look-up table for an equivalent device dependent four component colorant combination for a given printer from a given device independent three dimensional color space. First input parameters are comprised of varying percentage amounts of an additional fourth colorant and corresponding measured color values for varied percentage amounts of the additional fourth colorant. Second input parameters are comprised of varying percentage amounts of three base colorants and corresponding measured color values for varied percentage amounts of the three base colorants. Percentage amounts of the three base colorants (three colorant values) for each varied percentage amount of the additional fourth colorant are determined from the sets of measured color values.

Abstract: A graphical user interface may used to construct a list from pre-defined and user-defined printer values. Predefined values may be added or removed through a dialog box by selecting or deselecting values. New user-defined values may added by filling in a value in the add value dialog. An existing value may be modified by selecting a modify push-button. In response to selecting the modify push-button, a value may be edited in a modify value dialog. Adding, removing, modifying, and deleting printer values may be performed by user interaction with various push-buttons and dialog boxes.
