Problems solved by technology

[0012] On the other hand, since the operating system (OS) and device driver on the computer use the PCI device, if the PCI device is deleted through the PCI manager while the OS is running, it may occur due to I / O disconnection. There is a problem due to OS failure
[0013] In particular, the occurrence of such failures cannot be tolerated in servers that perform important tasks, and there is a big problem

no. 2 Embodiment approach

[0091] Next, the configuration of the composite computer system according to the second embodiment of the present invention will be described. The configuration of the composite computer system in the second embodiment is compared to figure 1 In the configuration of the composite computer system of the first embodiment shown, the connection between the PCI manager 104 and the multi-routers 1011 and 1012 is changed, and the other configurations are the same as those of the above-mentioned first embodiment. Therefore, only the parts different from those of the first embodiment will be described below, and the description of the same parts will be omitted.

[0092] Figure 19 It is an explanatory diagram showing an example of a PCI tree managed by the PCI manager 104 of the composite computer system according to the second embodiment. In this embodiment, the BMC 1901 is mounted on the multi-route PCI switches 1011 and 1012 , and the PCI manager 104 is connected to each BMC 1901...

no. 3 Embodiment approach

[0094] Next, the configuration of the composite computer system according to the third embodiment of the present invention will be described. The configuration of the composite computer system in the third embodiment, with respect to figure 1 In the composite computer system according to the first embodiment shown, the method for obtaining the PCI tree state by the physical host PCI tree state obtaining unit 133 is changed, and other aspects are the same as those in the above-mentioned first embodiment. Therefore, only the parts different from those of the first embodiment will be described below, and the description of the same parts will be omitted.

[0095] Figure 20 It is an explanatory diagram showing an example of a method for obtaining the PCI tree state information 136 by the physical host PCI tree state obtaining unit 133 of the hybrid computer system according to the third embodiment. In addition, in Figure 20 In order to simplify the description, only the above...

no. 4 Embodiment approach

[0110] Next, the control of the composite computer system according to the fourth embodiment of the present invention will be described. The control of the composite computer system in the fourth embodiment is in Figure 11 as well as Figure 16 In the control of the composite computer system in the first embodiment shown, a process of judging whether the power of the physical hosts 1001 and 1002 can be turned on or not is added according to the policy set by the user or the device administrator, and the rest is the same as in the first embodiment. . Therefore, only the parts different from those of the first embodiment will be described below, and the description of the same parts will be omitted.

[0111] Figure 22 Shown is a flowchart showing an example of power-on determination processing when power is turned on to a physical host computer of the hybrid computer system according to the fourth embodiment of the present invention. In the first embodiment above Figure ...

Abstract

The present invention can assure that a PCI tree to be allocated to a computer is configured completely before the computer is powered. The invention includes a PCI switch that connects plural computers through PCI interfaces; plural PCI devices connected to the PCI switch; a system controller that controls the computers; and a PCI manager that controls allocation of the PCI devices to the computers; and includes the steps of powering an object computer to start up its OS; acquiring the identifier of a PCI tree allocated by the system controller to the computer and PCI tree management information denoting the status of the PCI tree; retrying the powering or canceling the powering of the computer if the acquired PCI tree management information denotes the status not initialized; and carrying out the powering for the computer if the acquired PCI management information denotes the status initialized.

Description

technical field [0001] The present invention relates to the device management technology of the composite computer system that connects multiple computers and multiple PCI devices with PCI switches, especially relates to the initialization and power control technology of the computer when the PCI device is assigned to the computer and the change on the computer A control technique at the time of allocation of allocated PCI devices. Background technique [0002] An IT system represented by an Internet site is composed of various servers such as a WEB server that displays information to users, an AP (Application) server that combines and processes information, and a DB (Data Base) server that accumulates and stores information. , computers composed of CPUs, memories, I / O devices, etc. are used in these servers. As mentioned above, an IT system is constituted by many servers, so in recent years, a blade server (blade server) in which a plurality of computers are mounted on one...
