Many information processing devices include a diagnostic device that can diagnose a plurality of circuit devices included in the information processing device.

In such a case, when the diagnostician replaces the printed circuit board package on which the faulty circuit device is mounted with a new printed circuit board package, even if only the mounting position in the information processing apparatus is known, the new printed circuit board package can be used. It is desired that a diagnosis for confirming the normality of a package be easily enabled.

[Conventional technology]

FIG. 5 is a diagram showing an example of a conventional diagnostic device for an information processing device.

In FIG. 5, a plurality of various circuit devices constituting the information processing apparatus, for example, the exchange 10, are mounted by being divided into a plurality of printed board packages, and a plurality of such printed board packages are respectively provided on one to a plurality of apparatus racks. It is mounted detachably on the shelf.

For example, the central control unit CC0 constituting the processing unit MPR as a circuit unit of the exchange 10 is a specific printed board package PCB1,13 mounted on the processing unit shelf CPSHA / 12 provided in the processing unit rack CPF.11. Has been implemented.

On the other hand, the exchange 10 is provided with a diagnosis execution unit 14 for diagnosing a plurality of various circuit devices constituting the exchange.

Central control unit C in the processing unit MPR, for example a circuit unit
In the case of the diagnosis of C0, the tester inputs the following commands from the input / output unit 21 provided on the maintenance console 20 attached to the exchange 10.

DIA: MPR, CC = 0,0, U; Here, DIA indicates that the input command is a diagnostic command, MPR and CC = 0 indicate a diagnostic circuit device by name, and 0 indicates a diagnostic range. (Function type to be diagnosed), and U indicates the output format of the diagnostic result (whether only the comprehensive result or the test item, etc.).

Based on the diagnostic command [DIA: MPR, CC = 0,0, U;] input from the input / output unit 21, the diagnostic execution unit 14 sends a command to the central control device CC0 mounted on the printed circuit board package PCB0.13. Then, the diagnosis in the specified range is executed, and the diagnosis result is returned to the input / output unit 21 in the specified format.

The input / output unit 21 outputs a diagnosis result returned from the diagnosis execution unit 14.

Therefore, for example, after a failure occurs in the central control device CC0 in the processing device MPR, the printed circuit board packages PCB0 In order to confirm the normality of the above, after confirming that the circuit device mounted on the printed board package PCB0.13 is the central control device CC0 of the processing device MPR, the above-described diagnostic command [ DIA: MPR, CC = 0,0, U;].

[Problems to be solved by the invention]

As is clear from the above description, with respect to the conventional diagnostic device, when confirming the normality of the printed board packages PCB0 and 13, the circuit devices mounted on the printed board packages PCB0 and 13 (for example, configuring the processing device MPR) After confirming the central control unit CC0), it is necessary to construct a diagnostic command [DIA: MPR, CC = 0,0, U;] for designating the confirmed circuit unit by name.
A great deal of knowledge about circuit devices and mounted printed circuit board packages was required.

Also, if the replaced printed board package mounts circuit devices related to a number of other circuit devices, such as a channel control device CHC, as circuit devices, the circuit device to be diagnosed including the related other circuit devices Had to be specified.

The present invention makes it possible to easily confirm the normality of a printed circuit board package on which a diagnostic circuit device is mounted without requiring a great deal of knowledge about a plurality of circuit devices constituting an information processing device and a mounted printed circuit board package. The purpose is to:

[Means for solving the problem]

According to the present invention, there is provided a diagnostic apparatus for an information processing apparatus having a plurality of printed board packages each mounting one or a plurality of circuit devices (200), as shown in the principle diagram of the present invention in FIG. The minimum diagnostic circuit device necessary for confirming the normality of the printed circuit board package, based on the diagnostic command including the mounting position information of the printed circuit board package mounted in the information processing device, which is input from the output device (100). Conversion means (400) for converting to a diagnosis command consisting of a name, and diagnosis execution means (300) for executing a diagnosis for confirming the normality of the printed board package by the diagnosis command output from the conversion means. This is achieved by a diagnostic device for an information processing device characterized by the fact that one or more circuit devices (200) are respectively mounted. In a diagnostic method for an information processing apparatus having a plurality of printed board packages, a diagnostic command, which is input from an input / output device and is composed of mounting position information of a printed board package installed in the information processing apparatus, is provided. Converting to a diagnostic command consisting of a minimum diagnostic circuit device name required for normality confirmation, and executing a diagnosis for confirming the normality of the printed board package by the diagnostic command output by the conversion. This is achieved by a diagnostic method for an information processing apparatus characterized by the following.

[Action]

When a failure occurs in the information processing device, the diagnostic command clarifies the faulty circuit device through a complicated diagnostic step, and further diagnoses the faulty circuit device by the diagnostic command. The printed board package on which a certain circuit device is mounted is determined.

The printed circuit board package on which the circuit device in the failure state is mounted is replaced by a new printed circuit board package by a maintenance person, and the maintenance person needs to confirm the normality of the new printed circuit board package.

However, the maintainer may not necessarily have knowledge of the relationship between a plurality of circuit devices constituting the information processing device and a plurality of printed circuit boards on which one or more circuit devices are mounted, In this case, the maintenance person is not in a position to know the name of the circuit device necessary for composing the diagnostic command for confirming the normality of the printed board package itself.

Even in such a case, the maintenance person knows that the mounting position of the target printed circuit board package is, for example, the number of the printed circuit board package inserted in the processing apparatus shelf of which stage in which processing apparatus rack, When the maintenance person inputs a diagnostic command including the mounting position information of the target printed board package from the input / output device, the diagnostic command including the mounting position information is used by the converter according to the present invention to confirm the normality of the printed board package. The diagnostic command is changed to a diagnostic command including the minimum circuit device name necessary for the operation, and the normality of the printed board package is confirmed by the diagnostic execution unit by the converted diagnostic command.

That is, according to the present invention, even if the maintenance person does not recognize the minimum circuit device name necessary for creating a diagnostic command for confirming the normality of the printed circuit board package on which the diagnostic circuit device is mounted, the target print is performed. By simply inputting a diagnostic command consisting of mounting position information of the board package, a diagnostic command for confirming the normality of the printed board package on which the diagnostic circuit device is mounted is automatically created, enabling diagnosis. .
