    • A technology in which a magnetic disk apparatus executes data relocation involves the problems how to cope with new setup of file management and hardware failure and performance drop at the time in a data relocation. The invention provide a technology capable of executing data relocation without moving physical data position by a magnetic disk control apparatus when a disconnection operation of a logical volume is made, while keeping setup of an existing file management system. Therefore, the magnetic disk control apparatus is provided with means for keeping a file position information list inside a logical volume, executing optimal data reorganization in such a fashion as to eliminate fragmentation of the list and updating a physical/logical address mapping table. Reorganization of the logical file position is made without the data movement.
    • 磁盘装置执行数据重定位的技术涉及在数据重定位时如何应对文件管理新的设置和硬件故障以及性能下降的问题。 本发明提供一种能够在保持对现有文件管理系统的建立的同时,在进行逻辑卷的断开操作的同时由磁盘控制装置执行数据重定位而不移动物理数据位置的技术。 因此,磁盘控制装置设置有用于将文件位置信息列表保持在逻辑卷内的装置,以消除列表分段和更新物理/逻辑地址映射表的方式执行最佳数据重组。 逻辑文件位置的重组是在没有数据移动的情况下进行的。

    • A data transferring method is provided which can perform a data transfer without stopping transactions, without introducing a new device or without halting an access to a tape device by a higher-level device as would otherwise be required by a data transfer procedure. A technology is provided whereby a host computer controls an access request to a tape volume by managing and using information about source/destination tape devices (e.g., magnetic tape library management table and virtual tape management table) or data transfer state in a journal. As a result, even if an access request is issued from other device to a tape volume currently being data-transferred, the access can be made to the tape volume of interest without stopping transactions, i.e., a data transfer can be realized without an interruption of service.
    • 提供一种数据传输方法,其可以在不停止事务的情况下执行数据传输,而不引入新设备或者不停止由数据传输过程要求的上级设备对磁带设备的访问。 提供了一种技术,由此主计算机通过管理和使用关于源/目的磁带设备(例如,磁带库管理表和虚拟磁带管理表)或日志中的数据传输状态的信息来控制对磁带卷的访问请求。 因此,即使从其他设备向当前正在进行数据传送的磁带卷发出访问请求,也可以在不停止事务的情况下对访问磁带卷进行访问,即可以在不中断的情况下实现数据传输 的服务。
