Abstract: When a primary computer is taken over to a secondary computer in a redundancy configuration computer system where booting is performed via a storage area network (SAN), a management server delivers an information collecting/setting program to the secondary computer before the user's operating system of the secondary computer is started. This program assigns a unique ID (World Wide Name), assigned to the fiber channel port of the secondary computer to allow a software image to be taken over from the primary computer to the secondary computer.

Abstract: In a data processing system which runs a plurality of operating systems, a channel device can be shared by the plurality of operating systems. In addition, a channel device which supports port multiplexing can also be shared by a plurality of operating systems. The channel device includes a plurality of IDs each indicating that the channel device is a medium for performing input/output processing, and an input/output processing controller for assigning one operating system to each of the IDs, and controlling a data transfer independently for each ID to control a plurality of data transfers. Further, in a channel device which has a plurality of ports, an input/output processing controller is provided for assigning an operating system to each of the ports, and transferring data independently for each port to control the plurality of ports.

Abstract: Data processing arrangements including a channel adaptor shared by a plurality of operating systems (OS's) for data transmission/reception, coupled to the PCI bus on a PCI bus side of the channel adapter, and including only one connecting port on an input/output (I/O) side of the channel adaptor. An input/output process is executed between each OS and the channel adaptor by using input/output process control data specifying I/O data each having an identifier. Configuration information is provided, defining the identifier of the input/output process control data which is usable by each respective OS. The channel adaptor can process a plurality of input/output process control data; and each OS uses the input/output process control data corresponding to a usable identifier and defined in the configuration information, and thereby, a plurality of OS's control input/output process control data have different identifiers relative to the channel adaptor to execute the input/output process.

Abstract: A channel adaptor is provided which can be shared by a plurality of operating systems (OS's) running in a data processing system, by generating an address translation table without changing input/output process control data. A plurality of OS's execute an input/output process for the channel adaptor by using input/output process control data having different identifiers, without sharing the input/output process control data for the channel adaptor by different OS's. The data processing system generates one virtual address translation table from a plurality of address translation tables generated by OS's, and the channel adaptor processes the input/output control data of OS's by using the virtual address translation table.
