Abstract: An assembly includes a vehicle frame having a crossmember defining a passage. The assembly includes a drive unit supported by the crossmember in the passage. The assembly includes a stabilizer fixed to the drive unit, the stabilizer permitting movement of the drive unit in a first direction relative to the passage and restricting movement of the drive unit in a second direction opposite the first direction.

Abstract: A vehicle includes a window and a striker positioned to strike the window. The vehicle includes an actuator positioned to drive the striker. The vehicle includes a temperature sensor in communication with the actuator.

Abstract: Provided are a method, system, and article of manufacture, wherein a request to write data to a storage medium is received. The data requested to be written to the storage medium is stored in a cache. A writing of the data is initiated to the storage medium. A periodic determination is made as to whether the stored data in the cache is the same as the data written to the storage medium.

Abstract: In a data storage controller, accessed tracks are temporarily stored in a cache, with write data being stored in a first cache (such as a volatile cache) and a second cache and read data being stored in a second cache (such as a non-volatile cache). Corresponding least recently used (LRU) lists are maintained to hold entries identifying the tracks stored in the caches. When the list holding entries for the first cache (the A list) is full, the list is scanned to identify unmodified (read) data which can be discarded from the cache to make room for new data. Prior to or during the scan, modified (write) data entries are moved to the most recently used (MRU) end of the list, allowing the scans to proceed in an efficient manner and reducing the number of times the scan has to skip over modified entries Optionally, a status bit may be associated with each modified data entry.

Abstract: Provided are a method, system, and article of manufacture, where a plurality of extents are stored in a first set of storage units coupled to a controller. A determination is made that a second set of storage units has been coupled to the controller. The plurality of extents are distributed among all storage units included in the first set of storage units and the second set of storage units.

Abstract: A communication-path management system includes a path-detection component for identifying all communications paths between a host computer, through a controller, to a data storage device. Once identified, the communication paths are incorporated into a logical-path mask. The path-detection component recognizes each path as either preferred or non-preferred based on latency, bandwidth, availability, or other user-defined criteria and divides the logical-path mask into a preferred path subset and a non-preferred path subset. If a valid path exists in the preferred path subset, all communications from the host computer to the data storage device transit paths belonging to this subset. Otherwise, active control is given to the non-preferred path subset. A channel subsystem manages actual communication based on resource allocation and contention using the currently active subset.

Abstract: A method, apparatus and program storage device for protecting data write operations against write failures in a data storage device is provided. The data storage device includes a storage medium, a write cache including a copy of data written to the storage medium, and a controller configured for testing data write operations to the storage medium. The controller tests data write operations to the storage medium before the write cache is flushed to confirm that it is safe to flush the write cache. If the test fails, the data in the write cache can be recovered.

Abstract: Provided are a method, system, and article of manufacture, wherein a request to write data to a storage medium is received. The data requested to be written to the storage medium is stored in a cache. A writing of the data is initiated to the storage medium. A periodic determination is made as to whether the stored data in the cache is the same as the data written to the storage medium.

Abstract: One aspect of the invention is a method for configuring an array of storage devices to reduce the probability of data loss due to clustered storage device failures in the array. An example of this method includes identifying all storage devices in a primary set of storage devices and a first mirror set of storage devices in the array of storage devices. This example also includes obtaining data regarding each identified storage device. This example further includes determining if any of the storage devices in the primary set of storage devices has a vital characteristic that is the same as a vital characteristic of any of the storage devices in the first mirror set of storage devices, and if so, indicating an array configuration error, and if not, continuing the configuration.

Abstract: Disclosed is a method, system, and program for managing metadata in cache. A first policy is used to determine when to remove data from a primary cache, and a second policy is used to determine when to remove data from a metadata cache.

Abstract: A method to initialize information disposed in an information storage and retrieval system comprising a data cache and one or more information storage media comprising a plurality of addresses. The method receives an initialization command, where that initialization command comprises a range of addresses and, optionally, an initialization pattern, where the plurality of addresses includes the range of addresses. The method forms and saves state information, where that state information includes the initialization pattern, and generates and saves a plurality of indicators, where that plurality of indicators includes an indicator for each track comprising the range of addresses. The method sets each of those indicators to a first value thereby indicating special handling, and provides an ending status signal, such that the receiving step, forming step, generating step, setting step, and providing step are performed substantially synchronously.
