Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention manages the mounting state of each hardware device with respect to a central control unit of the information processing system by software when the system of the information processing system is started up or when a hardware device is added. The present invention relates to a hardware mounting state management system.

[0002]

2. Description of the Related Art Up to now, in an information processing system such as an electronic computer or an electronic exchange, data such as a device type and a device number of a hardware device to be connected to a central control unit of the system is previously stored as hardware mounting state data. As a result, hold it in the program that starts the system, and when starting the system or adding hardware devices,
It is known that the processing by the program manages the mounting state by connecting each hardware device described in the hardware mounting state data to a central control unit.

[0003]

However, in the above-described method, when the installation position of the hardware device is wrong, the connection process (mounting process) of the hardware device by the program at the time of system startup is performed. However, a hardware device different from the one recognized by the central control device side is connected to the central control device, and as a result, inconveniences such as inflow of abnormal data and abnormal interruption may occur, resulting in system disturbance.

Further, even if the hardware mounting state data itself held in the program has an erroneous setting, a hardware device different from the one recognized by the central controller is connected to the central controller. However, the same problem as in the case where the installation position of the above hardware device is incorrect occurs.

Further, when the system disturbance occurs, the cause thereof is not only the above-mentioned mistake of the installation position of the hardware device, the erroneous setting of the hardware mounting state data, the failure of the hardware device, The hardware mounting state data may be destroyed, but it is difficult to determine which cause is caused, and there is also a problem that it takes time to recover from the failure. And, in the case of a large-scale information processing system which is a so-called online system, such a problem becomes more serious.

The present invention has been made in view of the above circumstances, and a hardware device different from the one recognized by the central controller is connected to the central controller when the system is started up or a hardware device is added. It is possible to prevent the occurrence of inconveniences, and thus to prevent system disturbance caused by the fact that a hardware device different from the one recognized by the central controller is connected to the central controller. At the same time, it is an object of the present invention to provide a hardware mounting state management method capable of facilitating investigation of the cause when a system disturbance occurs and speeding up failure recovery.

[0007]

According to a hardware mounting state management system of the present invention, a program for causing a central control unit of an information processing system to execute a predetermined process is executed by a hardware unit connected to the central control unit. The hardware mounting status data in which the data such as the device type and the device number is set is retained and stored in the program when the information processing system is started up or when the hardware device connected to the central control device is added. It is for managing the mounting state of the hardware device with respect to the central control unit based on the held hardware mounting state data.

However, each hardware device provided to connect to the central control device is equipped with a device data holding means for storing data such as its own device type and device number.

Further, a normal route for enabling a data transfer between the central control unit and each hardware device is provided with a dedicated route for reading out the data stored in the device data holding means of each hardware device. Be equipped separately from the route.

Further, the program manages the mounting state of each hardware device with respect to the central control unit when the system of the information processing system is started up or when a hardware device connected to the central control unit is added. For this purpose, a device data reading function, a hardware determination function, and a hardware connection control function are provided in advance.

Here, the device data reading function is
It is a function of reading the data of the device data holding means equipped in each hardware device to be mounted using the dedicated route.

The hardware determination function is a function of comparing the data of the device data holding means read by the device data reading function with the contents of the hardware mounting state data and determining whether or not they match. .

Further, the hardware connection control function is
The hardware device determined by the hardware determination function that the data in the device data holding unit matches the content of the hardware mounting state data is placed in an operation state in which data transfer is possible through a normal access route, and the hardware determination is performed. The hardware device determined by the function that the data in the device data holding means does not match the contents of the hardware mounting state data is separated from the normal access route without connecting to the central control unit by the normal access route. It is a function to maintain the state.

[0014]

With the hardware mounting state management system according to the present invention, when the system is started up or when a hardware device is added, the installation position of the hardware device is erroneous or the data of the hardware mounting state data is erroneously set. If there is any, the hardware determination function equipped in the program makes a determination of inconsistency, and the hardware device for which a determination of inconsistency is made is made from the normal accelerator route by the hardware connection control function provided in the program. It is set to a separate state to avoid connecting to the central controller via normal access routes.

Therefore, it is possible to prevent the inconvenience that a hardware device different from the one recognized by the central controller is connected to the central controller, and a hardware device different from the one recognized by the central controller is provided. It is possible to prevent the disturbance of the system due to being connected to the central controller.

In addition, even if a system disturbance occurs, it is possible to easily confirm the actual installation state of the hardware device from the data of the device data holding means equipped in each hardware device. Compared with the conventional case where it is difficult to confirm the installation state of the device, the cause of the system disturbance can be easily investigated, and the restoration of the failure can be speeded up.
