    • Provided is a computer system including at least one host computer; and at least one storage system, characterized in that: the storage system has a disk drive and a disk controller, and provides a storage area of the disk drive as at least one logical unit; upon detecting a failure in a logical path serving as an access route from the host computer to the logical unit, the host computer specifies logical paths for accessing the same logical unit that is connected to the logical path where the failure is detected; the host computer executes failure detecting processing for the specified logical paths to judge whether the specified logical paths are normal or not; the host computer selects normal logical paths out of the specified logical paths; and the host computer accesses the logical unit via the normal logical paths selected.
    • 提供了一种包括至少一台主机的计算机系统; 以及至少一个存储系统,其特征在于:所述存储系统具有磁盘驱动器和磁盘控制器,并且提供所述磁盘驱动器的存储区域作为至少一个逻辑单元; 在检测到从主计算机到逻辑单元的访问路由的逻辑路径中的故障时,主计算机指定用于访问连接到检测到故障的逻辑路径的相同逻辑单元的逻辑路径; 主计算机对指定的逻辑路径执行故障检测处理,以判断指定的逻辑路径是否正常; 主机从指定的逻辑路径中选择正常的逻辑路径; 并且主机通过所选择的正常逻辑路径访问逻辑单元。

    • A ram driving method including the steps of fixing one end of a large-diameter piston rod integral with a large-diameter piston reciprocably included in a large-diameter cylinder attached integrally to a ram to a fixing unit, connecting one end of a small-diameter piston rod integral with a small-diameter piston reciprocably included in a small-diameter cylinder integral with the large-diameter cylinder to a moving member moved by a motor driving, integrally moving the small-diameter cylinder and the small-diameter piston and communicating a first compartment and a second compartment of the large-diameter cylinder divided by the large-diameter piston with each other, moving the ram integrally with the small-diameter piston rod moved by the moving member, and communicating the small-diameter cylinder with the large-diameter cylinder, thereby moving the large-diameter cylinder with a strong force by a working fluid supplied from the small-diameter cylinder.
    • 一种冲头驱动方法,包括将大直径活塞杆的一端固定在大直径活塞上的步骤,所述大直径活塞杆可往复运动地包括在一体地连接到冲头的大直径圆筒中, 该直径活塞杆与小直径活塞一体地包括在与大直径圆筒形成一体的小直径圆筒中,并通过马达驱动而移动的移动构件,使小直径圆筒和小直径活塞整体移动,并且连通 大直径圆筒的第一隔室和第二隔室由大直径活塞分开,使活塞与由移动构件移动的小直径活塞杆一体地移动,并将小直径缸与 大直径圆筒,从而通过从小直径圆柱体供给的工作流体以大的力移动大直径圆筒。
