摘要： A method, apparatus and computer program for controlling data migration in an information processing system which includes a central processing unit (CPU), a new storage system connected to the CPU and an old storage system connected to the new storage system. In the information processing system data migration is conducted to transfer data from the old storage system to the new storage system. The invention operates by permitting access by the CPU to the storage systems during data migration. When an access by the CPU is generated the invention determines whether the access is to a region where data migration has been completed or to a region where data migration has not been completed. If the access is to a region where data migration has been completed, then processing of the access is handled by the new storage system. If the access is to a region where data migration has not been completed, then processing of the access is handled by the old storage system causing data related to the access to be transferred from the old storage system to the new storage system. The speed of data migration can be adjusted based upon the utilization of the resources of the information processing system and information of the priority of access to the new storage system by the CPU.

摘要翻译：一种用于控制信息处理系统中的数据迁移的方法，装置和计算机程序，其包括中央处理单元（CPU），连接到CPU的新存储系统和连接到新存储系统的旧存储系统。在信息处理系统中，进行数据迁移以将数据从旧存储系统传送到新的存储系统。本发明通过在数据迁移期间允许CPU访问存储系统来操作。当产生CPU的访问时，本发明确定访问是否到达数据迁移已经完成的区域，还是数据迁移尚未完成的区域。如果访问是在完成数据迁移的区域，那么访问的处理由新的存储系统处理。如果访问是在数据迁移尚未完成的区域，则由旧存储系统处理访问，导致与访问有关的数据从旧存储系统传输到新的存储系统。数据迁移的速度可以根据信息处理系统的资源利用率和CPU对新存储系统的访问优先级的信息进行调整。

摘要： For a computer system having a central processing unit, an external storage unit which records data in a count-key-data (CKD) format, and a storage control unit with a cache memory for controlling data transfer between the external storage unit and the central processing unit, a computer system and data search method is provided which can prevent the performance of the central processing unit from being lowered and can eliminate signal transfer between the central processing unit and storage control unit during most of a data search operation period, by disconnecting the storage control unit from the central processing unit. During the data search operation, upon reception of a search command for the first record, a quasi completion report is issued to disconnect the storage control unit from the central processing unit. The storage control unit executes the search operation by using data loaded in the cache memory of the storage control unit. After data is searched, a search completion report is issued. Since the storage control unit is disconnected from the central processing unit during most of the data search operation period, the central processing unit is not occupied during this period by the storage control unit. Signal transfer is therefore unnecessary between the central processing unit and storage control unit during the data search operation period, making it possible to elongate a physical distance between the central processing unit and storage control unit.
摘要翻译：对于具有中央处理单元的计算机系统，以计数密钥数据（CKD）格式记录数据的外部存储单元和具有用于控制外部存储单元和中央处理器之间的数据传输的高速缓冲存储器的存储控制单元处理单元，计算机系统和数据搜索方法，其可以防止中央处理单元的性能降低，并且可以在数据搜索操作期间的大部分期间消除中央处理单元与存储控制单元之间的信号传送，通过断开来自中央处理单元的存储控制单元。在数据搜索操作期间，在接收到第一记录的搜索命令时，发出准完成报告以将存储控制单元与中央处理单元断开连接。存储控制单元通过使用加载在存储控制单元的高速缓冲存储器中的数据来执行搜索操作。搜索数据后，会发出搜索完成报告。由于在大部分数据搜索操作期间存储控制单元与中央处理单元断开连接，所以在此期间中央处理单元不被存储控制单元占用。因此，在数据搜索操作期间，中央处理单元与存储控制单元之间不必要进行信号传递，从而能够延长中央处理单元与存储控制单元之间的物理距离。

摘要： A technique is provided in which, even when the number of devices and device addresses handled in the storage apparatus side increases, it is possible to access all the devices and save used resources by simple control of the configuration definition information without adding the device addresses retained on the host side. The host side handles a virtual device for an access to an actual device handled on a storage apparatus side to retain a virtual device address, specifies an actual device to be mounted to the virtual device, and makes an access for data input/output by the virtual device address. A CHA of a controller maps an actual device address to a virtual device address and retains it in a table in a SM, and when receiving the access by the virtual device address, obtains the corresponding actual device address from the table to access the actual device.
