摘要： A system creates a configuration definition table to be used for accessing a physical disk according to a host I/O request, to decrease a memory size of the configuration definition table even if common firmware is used for models with different scales. For this, a model correspondence table to show the definition of each model is provided in a configuration setup processing module, the maximum values of this model are recorded in a memory based on this content, and a memory area for each item is secured. And the actual content of the configuration definition is developed on the secured memory. Therefore even for a diversity of models, the memory size of the configuration definition table can be decreased to a size matching the model, with common firmware regardless the model.

摘要： In the present invention, for each set of blocks [#(0) to #(N−1)] storing update data, a history block [#(N)] storing an update state value, for example, a generation, time or check code, showing an update state is provided, constituting a set of management data as a check object. When writing update data on a disk, a new update state value is calculated for the same set of management data and stored in memory as update state confirmation value. The new update state value is also set as write data in the history block in the same set of management data, and the entire of the set of management data including update data and update state value are written onto a disk. The history block is read and disk write omissions are detected by comparing the update state value and the update state confirmation value stored in memory.

摘要： A cache managing unit creates a list of elements corresponding to each data block arranged based on a priority of writing data blocks to a magnetic disk apparatus, and when a group of elements corresponding to data blocks to be written to the same magnetic disk apparatus exists, provides a link connecting elements at both ends of the group. A write control unit searches, upon selecting a data block for writing, elements belonging to the list in descending order of priority, and if a link is set at an element corresponding to a data block to be written to a magnetic disk that cannot perform a writing, follows the link to search a subsequent element.

摘要： A primary disk and a secondary disk that duplicates the data in the primary disk are connected to a host computer via a disk-array control unit. The disk-array control unit includes a plurality of central management units. Each central management unit includes a cache memory for writing data accessed, and a command-process executing unit that executes a process based on a command received. Each central management unit executes a process including determining, when there is an error in data stored in the primary disk while data stored in the secondary disk is normal, that a recovery process is necessary, duplicating, after completing an input/output process with the host computer, data written in the cache memory into a cache memory of any other central management unit, and writing-back the data written in the cache memory into the primary disk and the secondary disk.

摘要： An interdevice communication monitoring unit 62-1 calculates a variable timeout time (T2−T) by subtracting an elapsed time T from a predetermined fixed timeout time T2 for monitoring an intermodule communication to monitor an elapsed time of an intermodule communication. The fixed timeout time T2 is a time shorter than a predetermined interface connection check time T1 for monitoring an interface connection with a channel. When the elapsed time T of the intermodule communication exceeds the variable timeout time (T2−T), the interdevice communication monitoring unit requests a channel to separate the interface connection, and then when an end response is obtained from a control module, requests the channel for an interface reconnection and then transmits an end response.
