摘要： An input/output request sent from a host is once cued through a channel adapter and is then transferred to a resource manager and is cued, and the cuing is distributed. Even if sequential input/output requests of the host are separated through a distribution processing to a plurality of paths, they are recognized on the device controller side and a countermeasure is taken. In the case in which a path from the host to the device controller is caused to be redundant into an operation system and a standby system, a path confirmation command is issued to the device drivers of a standby system path in order to confirm that the standby system path is normally operated or not. When the issuance of the input/output request is transferred to another path, a command for releasing the reserve of a transfer path is issued from another path. In the case in which one path of a device driver of an operation system causes a fault, switching to the use of the path of the device driver of the standby system is carried out to implement a load balance through the same processing distribution driver as that obtained before the generation of the fault. Even if a difference in a channel transfer rate is made between the host and the device controller, a higher transfer rate can be maintained.

摘要： An ID portion indicating the corresponding relationship between the number of a record contained in an FBA block and the position of the record is provided at the beginning of the FBA block. When a seek command has been issued by a host apparatus in the CKD format, a device adapter obtains the FBA block number corresponding to the parameter value (CCHH) of a head positioning command and positions a head at the FBA block of this number. Next, the device adapter obtains the FBA block number corresponding to the parameter value (sector value) of a set-sector command, reads one CKD track of blocks from the FBA block designated by the FBA block number and develops these blocks in a cache memory. A channel adapter searches the cache memory for a commanded record by referring to the information in the ID portion.

摘要： A storage control apparatus concatenates a plurality of logical units to construct a large capacity logical unit, wherein logical units extending over a plurality of controllers can be concatenated. The channel adapter sends an I/O request to one controller which charges one logical unit constituting the concatenation logical unit, out of a plurality of controllers when an I/O request is sent from a host to the concatenation logical unit LU linking a plurality of logical units, executes I/O processing in the one controller, then sends the I/O request to another controller which charges another logical unit constituting the concatenation logical unit, and continues I/O processing in the another controller.

摘要： A disc array device for maintaining consistency of data. When write processing is interrupted and then restarted, new data may be stored in a nonvolatile memory and regeneration of parity may be impossible because data can not be read out normally from a disc device other than a disc device in which new data is to be written and a disk device for parity. In such a case, a special write executing unit overwrites the new data stored in the nonvolatile memory at a specified write position of the disk device in which new data is to be written.
