Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data processing device, and particularly to a connection method between a main body system device and a console device.

[Conventional technology]

The console functions for operating a data processing system include the system console function that controls the system configuration, the operator console function that performs message input/output with the operating system, and the service processor (diagnostic control unit). There are functions such as a maintenance console function that performs maintenance diagnosis control between

As a console, there is also a method of installing independent console devices for each of the above console functions.

A method of controlling screens by switching them on one console is generally used.

Conventionally, when performing the above-mentioned screen switching method, a method used as an interface connection method between a console device and a main body system device such as a central processing unit, and an input method used as an interface between a console device and a system to be rated. It has a connection port between the standard input/output interface from the output control device and the diagnostic interface between the 9 diagnostic control devices, and both interfaces are used for each communication depending on the console function. .

Here, FIG. 2 shows an example of a conventional system configuration.

The main system device is a central processing unit (hereinafter referred to as CPU) 10.11 that accesses and executes programs in a main memory device (hereinafter referred to as ``interval'') 12 via a system control unit (hereinafter referred to as SCU) 13. and an input/output control processor (hereinafter referred to as IOP) 1 that performs input/output control between peripheral devices according to instructions from the rating system.
5.16, and the console 19 is connected to a service processor (hereinafter referred to as SVP) 18.

Similarly, the two-body system device is MMU 22, SC

A console 29 is connected to the SVP 28.

SVP 18 is connected to IOPs 15 and 25 by input/output interfaces 105 and 206, respectively.

It has a function of controlling data transfer for communication from the SVP 18H console 19 to the operating system, as well as controlling maintenance and diagnosis of the main body system.

Inside the SCU 13, there are CPUs 10 and 11.

MMU 12, SCU 13, and IOP 15
, a diagnostic control unit (hereinafter referred to as DGU) 14 that performs diagnostic control of each of the 16 devices.
A DGU 24 is provided that performs a diagnostic test a for each of the devices IOP 23 and IOP 25 and 26. And S
YP 18 is connected to DGUs 14 and 24 by diagnostic interfaces 107 and 208, respectively, and SVP
28 are connected to DGUs 14 and 24 by diagnostic interfaces 108 and 207, respectively.

First, as an operator console function, the console 19
When a message is input from the SVP 18, the message data is sent from the SVP 18 to the IOP 1 via the i4 bus 105.
5, causing an interrupt to the operating system. In response to this interrupt, data is read and sent to the system.

For operating system color console output, start I/O operations and set IOP 15 or 2.
This is done by sending data from SVP 5 to SVP 18 and displaying it on console 19.

When used as a maintenance console function, by switching the console screen to a maintenance screen and inputting a message, the input instruction is passed to the SVP 18, and the svp
i s interprets the contents and performs necessary maintenance operations. If the maintenance operation requires access to the main unit, the svp i s 107 or 208
An instruction command is sent to the designated DGU 14 or 24. After the DGU 14 or 24 executes the maintenance operation, the DGU 14 or 24 sends the resulting data to the service 107 or 208.
SVP 18 displays it on console 19.

When a failure occurs in a device of the main system, the DGU 14 or 24 performs necessary failure handling operations and notifies the SVP 18 of the results using the same bus as described above.

In addition, when using the SVP 28 and the console 29, processing is also performed with G being tightly fitted as described above. SVP 28
are reversely connected to the IOPs 16 and 26 through input/output interfaces 106 and 205, respectively, and the SVP 28 controls data transfer from the console 29 to the operating system, and also has a maintenance/diagnosis control function for the main system equipment. There is.

The DGUs 14 and 2 are then connected to the DGUs 14 and 2 by the diagnostic interfaces 108 and 208 from the consoles 19 and 29, respectively.
4 can be used.

[Problem that the invention seeks to solve]

By the way, in the conventional system described above, it is necessary to provide two types of buses, an input/output interface and a diagnostic interface, from the main system device to the svp. For this reason, the interface between the devices is complicated and a large number of cables are required. When connecting a console device that also has a maintenance console function that inputs and outputs messages for maintenance diagnosis to and from a control device to the input/output control processor that controls input/output operations from the operating system and the diagnostic control device, a common Means is provided for connecting the console device via a bus.

That is, the input/output interface with the input/output control processor and the diagnostic interface with the diagnostic control device are connected to the console device through a common bus.

With reference to FIG.
PU 60, 61.

It is equipped with MMU 62 and IOP 65 and 66.

SVPs 58 and 68 are connected by a common bus 530.

That is, a bus 505 from 10P 55 and a nozzle 506 from IOP 56, which are input/output interfaces that serve as an interface with the O rating system, are connected to a bus adapter (hereinafter referred to as BADP) 57, and BADP 57 is connected to bus 530. connected to. Similarly I
OP 65 and 66 // are connected to bus 530 via BADP 67.

Diagnostic interface 50 from DGUs 54 and 64
7.607 is directly connected to bus 530.

Data transfer using bus 530 is performed when a data transfer requesting device specifies the destination device number and requests access to bus 530.

For example, when transferring data from the DGU 54 to the SVP 58, the DGU 54 can perform this by specifying the device number of the SVP 58 and making a data transfer request. BADPs 57 and 67, DGUs 54 and 64, SVP 58 also connected to bus 530
Data transfer can be performed between the 68 devices in any combination.

(In case of Menoseno output from the rating system to the console, input/output interface from IOP 5
03, 504, 603, and 604 is received by BADPK and transmitted from BADP onto bus 530.

The above configuration is as shown in the explanation in FIG.

IOP as operator console function (!r S
With the configuration of the present invention, data transfer between VPs and data transfer between DGU and svp as a maintenance console function can be performed in exactly the same manner as in the conventional configuration.

Furthermore, in the case of the present invention, by using the bus 530, it is also possible to perform communication between the DGU 54 and the DGU 64, and higher functionality can be achieved compared to the conventional system.

In addition, in the case of this embodiment, a method using an adapter for connection between the IOP and the gas 530 was shown, but
It is also possible to eliminate the need for BADP by configuring the IOP to be directly connectable to the bus.
