Abstract

PURPOSE:To easily point out a fault position by transferring detailed information on a fault to a central processor when a mechanism device in a communication control processor has the fault. CONSTITUTION:When the fault occurs in the communication control processor 22, a service control means 32 collects and stores temporarily fault information and a channel connecting means 33 is put in operation under the control of the service control means 32 to transfer the collected fault information to the central processor 21 through an input/output channel 23. Therefore, even when the continuation of normal operation is disabled and a fixed fault occurs to a constitution device of the communication processor 22, fault information on plural installed communication control processors 22 is gathered to the central processor 21, which fixes and recognizes the fault occurring device without sending any operator to the installation places of the respective communication control processors 22. Consequently, the fault position is easily pointed out.

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a failure information collection processing method for a communication control processing device that controls data communication between a central processing unit and a data communication line using a dedicated communication control program. It is.

[Conventional technology]

In recent years, in the field of computer systems, with the spread of distributed processing, it has become common to configure large-scale computer networks by complexly combining multiple central processing units and numerous data communication lines.

In such a computer network, a dedicated communication control program is installed to control data communication lines that require various transmission control procedures so as not to reduce the processing capacity of the central processing unit. It is conventional practice to connect a communication control processor that operates independently of the central processing unit to the human output channel of the central processing unit.

The central processing unit 2a has a plurality of ICs installed.

2b and 2c are communication control processing units 3a which are independently connected to each central processing unit la, lb and lc.

3b, 3c are input/output channels that connect the central processing units 1a, lb, lc and the communication control processing units 2a, 2b, 2C, respectively; data to connect to,
Communication lines 5a, 5b, 5c are terminals for data input/output; 6a, 6b, 6c are terminals 5a, 5b, 5c and a communication control processing device 2a.

FIG. 3 shows the communication control processing device 2a shown in FIG.

FIG. 2 is a block diagram showing the internal configuration of 2b and 2c.

In the figure, 2 is a communication control processing unit, 3 is an input/output channel connected to the central processing unit 1, 4 is a data communication line,
6 is a data communication line for the terminal; 7 is a channel control device that controls data transfer between the input/output channel 3 and the communication control processing device 2; 8 is a channel control device that stores a communication control program 9 and is connected to the data communication lines 4 and 6; 10 is a central control unit that controls the execution of the communication control program 9; 11 is a line control unit that controls data transfer between the communication control processing unit 2 and the data communication line 4.6; be.

Next, the operation will be explained. When data communication is performed using the program-embedded communication control processing device 2 having the configuration shown in FIG. 3, the program in the central processing device 1 prepares only communication destination information and a message; Exchange is performed with the communication control processing device 2 via the input/output channel 3. The subsequent specific processing related to data communication is performed by the communication control program 9 in the communication control processing device 2, and the central control device 10 actually reads out the commands of the communication control program 9 stored in the storage device 8 one by one. This is achieved by executing When transmitting data from the central processing unit 1 to the data communication line 4.6, the destination address and message sent via the input/output channel 3 are transmitted to the channel control unit under the control of the central control unit 10. 7 and is temporarily stored in the storage device 8. Next, the communication destination address is decoded under the control of the communication control program 9, and the message is added with transmission control characters according to the individual communication rules in accordance with the transmission control procedure preset for each communication line, and the communication is controlled by the communication line. The data is sent to the device 11 and parallelized/processed within the line control device 11.
After serial conversion, the signals are sent to data communication lines 4 and 6.

Contrary to the above, when the central processing unit 1 receives data from the data communication line 4.6, the data including transmission control characters sent from the data communication line 4.6 is serially transmitted within the line control unit 11. /parallel conversion is performed, transmission control characters are deleted under the control of the communication control program 9, and the message and destination information are assembled and stored in the storage device 8. Thereafter, the central controller 10 sends only this destination information and the message to the central processor 1 via the channel controller 7 and the input/output channel 3.

Through such processing by the communication control processing device 2, the central processing unit 1 is freed from complicated identification of transfer destinations related to data communication, addition and deletion of control characters in accordance with individual communication regulations, and the like.

Therefore, when a hardware failure occurs, collection of this failure information must be controlled by the central control unit 10 itself, making it difficult to collect detailed information. On the other hand, when transferring the failure information to the central processing unit 1, the central control unit 1
The channel control device 7 assembles several bytes of information based on the fault information collected by the channel control device 7, and sends it to the central processing device 1 as channel status information accompanying input/output operations from the central processing device 1 as a hardware operation of the channel control device 7. The problem is that the quality and quantity of failure information is insufficient, and if a fixed failure occurs in the central control unit 10 or channel control unit 7, failure information cannot be transferred. There was also.

In addition, in recent computer systems, when configuring a complex computer network, multiple central processing units 1 and 1

In response to these problems, recently, fault information from each device that makes up a computer system is collected in the central processing units 1a, lb, and lc, and the system fault information is organized and consolidated in a format that is easy for maintenance personnel and others to see, thereby improving maintainability. There is a growing demand to achieve this. However, the conventional communication control processing devices 2a and 2b.

2C cannot sufficiently transfer information to the central processing units 1a, lb, and lc, and the information is insufficient, and the central processing units 1a, lb, and lc cannot create accurate system failure information, and the above The problem was that it was not able to fully meet the demands.

This invention was made in order to solve the above-mentioned problems, and when a failure occurs in the mechanical device in the communication control processing unit, this detailed information can be transferred to the central processing unit, so that the central processing unit can It is an object of the present invention to provide a failure information collection processing method that can easily point out a failure location of a communication control processing device using created system failure information.
