    • In an electronic computer system in which a plurality of OSs are operated, a plurality of input-output arrangement information defined in response to each of a plurality of OSs and a correspondence table indicative of a correspondence relationship between each OS and each input-output arrangement information are created previously and stored in a control information storage means. When an input-output request is issued from an arbitrary OS, the central processing unit identifies the corresponding OS, and recognizes input-output arrangement information corresponding to the identified OS based on the correspondence table. Then, the central processing unit executes an input-output processing based on the recognized input-output arrangement information. According to the present invention, since one electronic computer system becomes able to use a plurality of input-output arrangement information at the same time, the maximum number of input-output arrangements can be distributed to each OS so that the data processing capability of the whole system can be improved considerably.

    • A connection method of a plurality of input/output channels between a plurality of sub-channels of an information processing system having a virtual machine running on a physical machine under control of a hypervisor and a plurality of devices. The method includes issuing from the hypervisor a command for setting configuration information defining a plurality of configuration structures between the sub-channels set for the respective virtual machines and the devices in a storage device and acquiring configuration information containing the sub-channel corresponding to a designated device from the configuration information corresponding to one of the virtual machines based on the device designation contained in the input/output command from the one virtual machine. The virtual machines are enabled after the issuance of the set command and before the issuance of the input/output command. The corresponding configuration information is searched by using ID information of the virtual machine which issued the input/output command in order to execute the step so that one of a plurality of channel paths between a plurality of devices and the sub-channels is selected to execute the input/output designated by the input/output command.
    • 信息处理系统的多个子信道之间的多个输入/输出信道的连接方法,具有在管理程序的控制下在物理机上运行的虚拟机和多个设备。 该方法包括从管理程序发出用于设置在针对各个虚拟机设置的子信道和存储装置中的设备之间定义多个配置结构的配置信息的命令,并且获取包含与指定的对应的子信道的配置信息 设备根据来自一个虚拟机的输入/输出命令中包含的设备指定从与虚拟机之一相对应的配置信息。 虚拟机在发出设置命令之后以及发出输入/输出命令之前启用。 通过使用发出输入/输出命令的虚拟机的ID信息来搜索相应的配置信息,以执行该步骤,使得选择多个设备和子信道之间的多个信道路径中的一个来执行 由输入/输出指令指定的输入/输出。
