    • 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 logical partitioned computer system. A hypervisor includes a resource management table for managing resources assigned to the hypervisor and an assigning/collecting unit for assigning and collecting resources to logical partitions. Each logical partiion has a guest resource monitoring unit for monitoring the amount of the resource being used out of the amount of the resource assigned to the logical partiion and an adding/separating unit for requesting addition and separation of a resource to the assigning/collecting unit based on results of monitoring. In response to the request, assigning/collecting unit searches resource management table, assigns a resource to logical partition when a reserve resource exists in case of an assignment request, and collects a resource as a reserve resource in the resource management table in case of a collection request.
    • 逻辑分区计算机系统。 管理程序包括用于管理分配给管理程序的资源的资源管理表和用于向逻辑分区分配和收集资源的分配/收集单元。 每个逻辑单元具有一个来宾资源监视单元,用于监视分配给该逻辑单元的资源量的正在使用的资源量;以及添加/分离单元,用于请求向分配/收集单元添加和分离资源 基于监测结果。 响应于该请求,分配/收集单元搜索资源管理表,当在分配请求的情况下存在预留资源时,将资源分配给逻辑分区,并且在资源管理表中将资源作为备用资源收集在资源管理表中 收集请求。
