    • In an information processing system including host computers and disk devices, each of an execution-node host and a standby-node host includes an I/O request unit and an access-right change command unit. The I/O request unit issues an I/O request. The access-right change command unit transmits an access-right change command. The access-right change command results from causing I/O-enable/disable information and the host identification information to correspond to each other. The disk device includes an access control table, an access control unit, and an access-right change unit. The access control table stores information of the access-right change commands from the hosts. The access control unit judges the execution enablement/disablement for the I/O requests from the host identification information and the access control table. The access-right change unit, in accordance with the access-right change commands from the hosts, changes in batch the I/O-enable/disable information on each host basis within the access control table.
    • 在包括主计算机和磁盘设备的信息处理系统中,执行节点主机和备用节点主机中的每一个包括I / O请求单元和访问权限改变命令单元。 I / O请求单元发出I / O请求。 访问权限改变命令单元发送访问权限改变命令。 访问权限改变命令是由于导致I / O使能/禁止信息和主机标识信息彼此对应而产生的。 磁盘装置包括访问控制表,访问控制单元和访问权限改变单元。 访问控制表存储来自主机的访问权限改变命令的信息。 访问控制单元从主机识别信息和访问控制表判断对I / O请求的执行启用/禁止。 访问权限改变单元根据来自主机的访问权限改变命令,在访问控制表内基于每个主机批量地改变I / O启用/禁用信息。

    • A restart method for restarting an operating system in a computer in which a failure has occurred, the restart method includes the steps of, upon occurrence of a failure in an active computer in which an operating system (OS) is in operation, ordering disconnection of an OS storing storage device from the active computer by using a processor, ordering connection of the OS storing storage device to a stand-by computer by using the processor, restarting the operating system in the OS storing storage device by using the stand-by computer, and outputting dump information to a dump information storing storage device, by using the active computer, in parallel with restart of the operating system conducted by the stand-by computer.
    • 一种用于在其中发生故障的计算机中重新启动操作系统的重新启动方法,所述重新启动方法包括以下步骤:在操作系统(OS)正在操作的活动计算机中出现故障时,排序 通过使用处理器从活动计算机存储存储设备的操作系统,通过使用处理器将存储存储设备的操作系统存储存储设备的顺序排序到备用计算机,通过使用备用计算机重新启动存储存储设备的操作系统中的操作系统 并且通过使用活动计算机与由备用计算机执行的操作系统的重启并行地将转储信息输出到转储信息存储存储装置。
