    • In creating replicas to data of a storage volume in a storage system, a technique in which labor for issuing instructions from a processor can be reduced and then data consistency of related volumes can be secured is provided. A single replication instruction including designated information is issued for data of a logical unit serving as a copy source and a copy destination from a replication-control program of the processor. A control unit of the storage system possesses a multiple-replica creation program which enables a processing for creating replicas while securing the data consistency when an access such as a update or reference occurs for a group including a plurality of pairs of copy-source volume and copy-destination volume based on reception of the instruction. A save volume is provided to identify and control data save and update state by copy-source save information and copy-destination update information at the shared memory.
    • 在创建存储系统中的存储卷的数据的副本时,提供了可以减少用于从处理器发出指令的劳动,并且然后可以确保相关卷的数据一致性的技术。 从处理器的复制控制程序发出包含指定信息的单个复制指令,用于作为复制源和复制目的地的逻辑单元的数据。 存储系统的控制单元具有多重副本创建程序,其能够在为包括多对复制源卷的组发生诸如更新或引用的访问时在保证数据一致性的同时进行创建副本的处理,并且 基于接收指令的复制目的地卷。 提供保存卷以通过复制源保存信息和复制目的地更新信息在共享存储器上识别和控制数据保存和更新状态。

    • Disclosed herein is a method for controlling a storage device controller connected to a storage device provided with a plurality of storage volumes for storing data respectively and an information processing apparatus for requesting an input/output of data so as to receive an input/output request from the information processing apparatus and execute an input/output processing of the data for each of the plurality of storage volumes. The method brings one (primary) of the plurality of storage volumes into correspondence with another (secondary) in which a copy of data is to be written when the data is written in the primary volume so as to form a pair group consisting of a plurality of pairs, each having such a primary volume and such a secondary volume. Upon receiving an input/output request from the information processing apparatus, the method starts resetting of the correspondence between storage volumes of each pair included in the pair group to decide whether or not it is after resetting of the correspondence is started that the request has been issued and executes an input/output processing after resetting the correspondence if the request is issued after resetting of the correspondence is started.

    • The following steps are performed in a storage system: when volumes configuring each volume pair are used by separate applications, storing, for each pair in a memory, an address where updating of data has been made in the volumes as updated-location-managing information; in case a destination-of-restoring copy volume configuring one pair is to be restored to have the contents of a source-for-restoring copy volume belonging to another pair, obtaining, from the memory, pieces of the updated-location-managing information for each of the pairs; generating differential information by merging the pieces of updated-location-managing information obtained, the differential information indicative of a difference in the pieces of updated-location-managing information between the copy volumes; and reproducing the destination-of-restoring copy volume to have the contents of the source-for-restoring copy volume, by copying data designated by the differential information from the source-for-restoring copy volume to the destination-of-restoring copy volume.
    • 在存储系统中执行以下步骤:当由单独的应用程序使用配置每个卷对的卷时,将存储器中的每对存储器存储在卷中进行数据更新的地址作为更新位置管理信息 ; 如果要恢复配置一对的恢复目的地的复制卷以具有属于另一对的恢复原始卷的内容,则从存储器获取更新位置管理信息的一部分 对于每一对; 通过合并获得的更新位置管理信息,指示复制卷之间的更新位置管理信息之间的差异的差分信息来产生差分信息; 并且通过将由差异信息指定的数据从恢复源复制卷复制到恢复复原卷的目的地,再现恢复复原卷的目的地以具有恢复源复制卷的内容 。

    • Regarding an independently driven type spindle in a spinning machine, when a yarn breakage is occurred in a spindle 10, a brake operating member 35 of the spindle 10 is moved toward a spindle shaft 13. During the movement of the brake operating member 35, control surfaces 49 of the brake operating member 35 cause the stop/restart switches 46 and 47 to be made OFF between the electric driving motor 20 and alternate current lines S and T, thereby causing the motor 20 to be rotated under its own momentum. Then, braking parts 34 of the brake operating member 35 is pressed to the outer peripheral surface of the spindle shaft 13, thereby executing a mechanical braking operation. After the withdrawal of an end of broken yarn, the brake operating member 35 is released, so that a force of the springs 41 causes the brake operating member 35 to be detached from the spindle shaft 13, thereby canceling the braking operation. The movement of the brake operating member 35 also causes the stop/restart switches 46 and 47 to be made ON, thereby restarting the drive motor 20.
    • 关于纺纱机中的独立驱动型主轴,当在主轴10中发生纱线断线时,主轴10的制动操作部件35向主轴13移动。在制动操作部件35的移动期间,控制 制动操作构件35的表面49使电动驱动电动机20和交流电流线S和T之间的停止/再起动开关46和47断开,从而使电动机20在其自身的动量下旋转。 然后,将制动操作部件35的制动部件34按压到主轴13的外周面,从而进行机械制动动作。 在退出纱线末端后,制动操作构件35被释放,使得弹簧41的力使制动操作构件35从主轴13拆卸,从而取消制动操作。 制动操作构件35的移动也使停止/重启开关46和47变为接通,从而重新启动驱动马达20。
