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.
摘要翻译：从主机发送的输入/输出请求一旦通过通道适配器提供，然后被传送到资源管理器，并被提示，并且分发。即使主机的顺序输入/输出请求通过分发处理分离成多个路径，它们在设备控制器侧被识别并采取对策。在从主机到设备控制器的路径在操作系统和备用系统中被冗余的情况下，向备用系统路径的设备驱动器发出路径确认命令，以便确认备用系统路径是否正常运行。当输入/输出请求的发送被传送到另一路径时，从另一路径发出用于释放传送路径的保留的命令。在操作系统的设备驱动器的一个路径导致故障的情况下，执行切换到备用系统的设备驱动器的路径的使用，以通过与该处理分配驱动程序相同的处理分配驱动程序实现负载平衡在发生故障之前获得。即使在主机和设备控制器之间进行信道传送速率的差异，也可以保持更高的传送速率。

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.
