Abstract: A storage system is configured to create and manage virtual ports on physical ports. The storage system can transfer associations between virtual ports and physical ports when a failure occurs in a physical port or a link connected to the physical port so that a host can access volumes under the virtual ports through another physical port. The storage system can also change associations between virtual ports and physical ports by taking into account the relative loads on the physical ports. When a virtual machine is migrated from one host computer to another, the loads on the physical ports in the storage system can be used to determine whether load balancing should take place. Additionally, the storage system can transfer virtual ports to a remote storage system that will take over the virtual ports, so that a virtual machine can be migrated to remote location.

Abstract: In one example, a method of detecting timing errors in a configuration of a programmable logic device (PLD) includes performing a timing analysis on the PLD configuration. The PLD configuration is adapted to configure the PLD to perform a data transfer between a first clock domain synchronized by a first clock signal received by a double data rate (DDR) block of the PLD configuration and a second clock domain synchronized by a second clock signal received by the DDR block. The method includes calculating a slack value associated with the data transfer using a first delay associated with the first clock signal, a second delay associated with the second clock signal, and a time constraint associated with the data transfer. The first delay and the second delay are provided by the timing analysis. The method includes determining whether the PLD configuration satisfies the time constraint based on the slack value.

Abstract: The subject matter of this specification can be embodied in, among other things, a method that includes identifying and restoring corrupted data stored, for example, on a portable media player. Some of the described implementations include synching a media player with a host device (e.g., a personal computer). During synchronization, the host device can query the media player to determine whether any media stored on the device should be replaced. For example, the host device can determine whether a corruption event occurred in association with a media file (e.g., whether the media player skipped the media file as unplayable). In another example, the host can determine whether portions of a media player's storage device are damage or “bad.” If a bad portion is detected, the host device can identify media stored on the portion as corrupt. After identifying corrupted media, the host can replace the media with valid copies.

Abstract: A CPU forced stop signal is used as means for stopping execution of a program executed on a ROM by a CPU of a target system. A time required for stopping the CPU from the issuance of the CPU forced stop signal between an ICE device and the CPU is considered and set, and a CPU forced stop signal issuance position which is prior to a stop target position is determined. Based on a real-time tracing function of the CPU, at an issuance position and timing of the CPU forced stop signal on the execution of the program, the CPU forced stop signal is issued, the CPU is stopped, and the event is acquired. By this means, an arbitrary number of events of the program can be acquired regardless of the number of breakpoint registers.

Abstract: A method, system and program are disclosed for validating the generation of globalized versions of software programs. The directory structure of an installed software program is traversed to discover resource files containing globalized strings. The values of the globalized string and its corresponding key in the resource file are then used to generate a unique key, formatted to identify the location of the globalized string. The locale supported by the globalized string is determined and the unique key and the globalized string value are appended to a corresponding locale table. A globalized string value that causes the failure of a globalization test for a predetermined locale is identified. The corresponding locale table is then searched for the failed globalized string value. Once found, the unique key for the failed globalized string value is retrieved to identify the location of the defective globalized string and perform predetermined remedial actions.

Abstract: This descriptive document is about a new backup device that takes advantage of the components of a PC's conventional power supply and it combines them with additional typical electronic components from an uninterruptible power supply (UPS). The result of such combination is a lower cost backup function that is applied directly to the PC and, therefore, eliminates the requirement of external devices—such as a UPS—to perform this backup function. In this document, the electronic components that combine with the PC's power supply in order to provide the backup functionality described above are referred to as integrated backup unit (URI).

Abstract: A method of generating a microcore file, which is a subset of a full core dump, for a networked storage system includes generating a microcore file according to a microcore specification, and dynamically defining the microcore specification at runtime of the network storage system. The microcore specification is dynamically defined with information provided by results of an event that triggers the generation of the microcore file. After the microcore specification is defined, a region of a system memory is identified according to the microcore specification. The method further includes dumping the data from the region of the system memory into the microcore file.

Abstract: A system for reporting and/or displaying errors in a system that affect end-user tasks includes mechanisms for gathering, interpreting and displaying application status information in a convenient display. In one implementation, for example, distributed application programs in a system are configured to provide status reports (e.g., positive, negative, pending) to a centralized reporting service. The centralized service stores the status information in a database. An event interpreter module queries the database to identify the status of certain application components that affect or otherwise implicate performance of generalized end-user tasks, such as sending/receiving email, logging-in to the network, accessing the internet, remote computer management, or the like.

Abstract: A software testing method. In particular implementations, a method includes accessing a first database of one or more bug entries, wherein each bug entry comprises information characterizing a bug, an associated code component, and a test script; and a mapping between the component and one or more scripts that test the code component; for one or more bug entries in the first database, determining if the bug is a new bug; if the bug is not a new bug, determining if the test script is new relative to the bug; and if the bug is a new bug or if the test script is new relative to the bug, accessing a second database of the script-to-component mappings to add a mapping between the test script and the associated code component of a respective bug entry.

Abstract: A management server obtains configuration information of an active server and creates a logical partition in a backup server so as to correspond to the active server. The backup server starts up the created logical partition. And when the created logical partition reaches a predetermined state, the backup server releases allocation of the first processor resource to the logical partition, thereby the logical partition stands by. The management server, when detecting an error occurred in the active server, stops the active server and searches the logical partition having same configuration as the active server in which error is detected, and enables allocation of the first processor resource to the searched logical partition, thereby completing the start-up of the logical partition.
