摘要： 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). Multiple parts, not being actively used by a process, may be combined by a merge function to represent the most current image of the track.

摘要翻译：一种用于通过选择性地生成，维护，修改和合并高速缓冲存储器中的数据项的多个版本以有效地容纳主机的数据访问请求来向多个主机提供并发访问缓存数据的系统。与逻辑磁道相关联的数据在高速缓存中由多个高速缓存轨迹图像部分表示。每个部分表示缓存中的一个或多个记录，其中多个部分可能存在于同一逻辑磁道的高速缓存中。提供多个部件支持通过多个操作或“进程”对与轨道相关联的数据的并发访问。即，各部分被赋予从预定状态目录中选择的“状态”; 因此，分配的状态确定了访问该部分的允许方式。根据部件的状态，该部件可以由一个进程（例如，读取）或多个进程同时使用（例如读取和传送）。其他部分状态将一部分专用于单个过程（例如写入）。多个部分，不被过程主动使用，可以通过合并功能组合以表示轨道的最新图像。

摘要： 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.

摘要： Disclosed is a method, system, program, and data structure for updating code in a first and second controllers. The first and second controllers are capable of accessing storage regions in a storage device. The first controller receives a code update and signals the second controller. Access to the first controller is disabled and the code update is applied to the first controller. In response to the signaling, the second controller receives commands directed to all of the storage regions during the code update to the first controller.

摘要： 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.

摘要： 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. The determined pointer and a request for the determined storage blocks is transferred to a component that is capable of accessing storage blocks in the second format in cache using the control block if the storage unit data structure includes a pointer to the control block.

摘要： Disclosed is a method, system, and data structures for updating data in a storage device. An update to one or more blocks of customer data at addresses in the storage device is received. For each block of data to update, metadata is generated indicating the address of the block in the storage device and an error checking code that is capable of being used to determine whether the customer data in the block has changed. For each block of data to update, the block of data to update and the metadata for the block are written to cache. Further, for each block of data to update, the block of data and the metadata are transferred for the block from the cache to the storage device. The metadata may be used during power loss and recovery.

摘要： Disclosed is a method, system, program, and data structure for executing write operations. A first number of write operations is initiated. Performance data is gathered indicating a total time for a second number of the initiated write operations to complete. After at least one initiated write operation has completed, at least one additional write operation is initiated if a number of outstanding write operations is less than a maximum number of write operations. The maximum number of write operations is adjusted if the performance data meets at least one threshold.

摘要： Implementations describe the expansion of storage space in an array of storage units. The storage space formed by the storage units is configured as logical units to store data. Storage units are added to the array to form an expanded storage space. The storage units in the array prior to the addition of the storage units are in a pre-expansion storage space. At least one additional logical unit is configured in the expanded storage space such that the logical units existing prior to the addition of the storage units in the pre-expansion storage space are not affected by the logical units configured in the expanded storage space.
