Abstract

PURPOSE:To prevent an error code, which indicates heavy trouble information, from being deleted by the error code which occurs frequently and indicates light trouble information, by eliminating automatically the display operation of an error log to which deletion is designated. CONSTITUTION:A maintenance service processor 1 is connected to a data processor (CPU) 2. Normally, trouble information from the CP2 is converted in a converting part 13 each time and is stored in an error log table 11c, and the error code which is displayed is replaced with this trouble information, and this trouble information is displayed on a display device 14 through a register 15. When an input part 16 is operated to designate deletion of the displayed error code, a control part 10 registers this error code in a deletion register table 11d and accesses an error log table 11c to set a flag of register deletion. Further, the control part 10 traces back addresses in order to display the error code, for which the flag is not set, on the display device 15. Thus, light troubles whose deletion is designated are eliminated automatically, and high-operability useful error code display is possible.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a method for displaying failure information of a maintenance service processing device in a data processing system.

(b) Background of the Technology In recent years, with the development and spread of data processing technology, data processing devices have come to be used in a wide range of fields.

In particular, with the development of semiconductor integrated technology, data processing devices such as central processing units (CPUs) have become smaller and more sophisticated, but at the same time, it is expected that higher operational and maintenance efficiency will be achieved due to further labor savings. ing. Therefore, the CPU
In order to improve the reliability and maintainability of the complex logic circuits that make up the circuit, a total of 9 parity detection methods are used to balance the cost.

In addition to incorporating means such as automatic correction (FCC) and retry, the state of the logic circuit's flip-flop circuit (FF) can be read out to facilitate diagnosis of the logic circuit and pointing out the location of failure (scanout), arbitrary test patterns. etc. (Skitafu 4F 9 circuits are introduced in the logic circuit of the CPU.The present invention writes failure information using various means for reliability and maintainability in the maintenance service processing device, for example, on a display. It is related to the method of displaying on the screen.

(c) Prior art and problems Conventionally, the maintenance service processing device (sv
As for the display means in p), each time all fault data is received, the fault type/occurrence location of the fault data is immediately displayed, for example, by an error code, regardless of the severity of the fault content. Therefore, in this method, the CPU
It can identify temporary minor failures that do not affect continuous operation, such as the activation of parity detection or automatic correction (ECC), as well as severe failures, such as failures due to logic circuit main power failure or damage to important circuit elements. Therefore, the severe earlier error code that was being displayed on the display screen is replaced with the frequently occurring mild later error code that hardly needs to be displayed, and the operator is unable to detect the severe earlier error code. The problem was that it was difficult to recognize the code. Further, even if the operator attempts to erase a minor error code each time using an input means such as a light pen or a keyboard, and display a desired severe error code, for example, the operation is cumbersome. ? There are cases where reproducibility is poor while the CPU is continuing to process a job.

(d) Purpose of the Invention The purpose of the present invention is to eliminate the above-mentioned drawbacks by using the conventional method of displaying error codes when the operator does not take any action; When the designation is made, the @ indicates the above-mentioned error code kN along with the deletion of the designated error code, and after the deletion designation, the display is controlled so as to suppress the display of the deletion designation error code registered in the deletion registration table. The present invention aims to provide an error code display method that automatically removes the deletion specification error code expected by the operator and displays the error code.

(e) Structure of the Invention The object of the present invention is to provide a maintenance service processing device that processes all fault information sent by a data processing device, the maintenance service processing device having a data log table and an deletion registration table in its storage section, and a system for storing fault information. The controller comprises a means for receiving and converting the error code into a display error code, a means for displaying the error code, a data input means using a light bench and a keyboard, and a means for buffering and storing the error code to be displayed. The error code to be sent is set in the data log table and buffer storage means each time and displayed on the screen of the display means, while when an error code to be deleted from display is specified by operation of the input means, the error code is set in the data log table and buffer storage means and displayed on the screen of the display means. The error code is registered in the buffer storage means and the display means, and the aforementioned error code in the data table is set and displayed in place of the error code in the buffer storage means and the display means. An error code characterized by accessing a deletion registration table and inhibiting setting of an error code that matches a registered error code in a buffer storage means and causing the display means to continue displaying the error code held in the buffer storage means. This can be achieved by providing a full display format.

(f) Embodiments of the Invention An example of the present invention will be described below with reference to the drawings. Fig. 1 is a block diagram of an error code display method in a laughable example of the present invention, and Fig. 2 (a), (b) (
c) I'i A flowchart showing the processing procedure is shown below.

In the figure, 1 is the maintenance service processing device (SVP), 2
is a data processing device, and 10 is, for example, a microprocessor (
11 is a storage section by RA OM, 12 is an input/output port by a peripheral relay adapter (PIA), and 13 is not shown, but it receives fault information from a fault detection section provided in the CPU 2. 14 is a display; 15 is a register that buffers and stores the error code to be displayed on the display 14; 16 is an input unit such as a light bench and a keyboard;
Note that 11a is a control program in the storage area of the storage unit 11, 11b is control data, 11c is an error log table, and lld is an deletion registration table. In the configuration shown in the figure, a control unit 10 accesses a storage unit 11, controls each component in accordance with a control program lla and control data llb, and processes fault information sent from the CPU 2. If the operator does not operate the input section 16 at this point, the
) As shown in K, as in the past, the fault information that is input to the CPU in large quantities is converted into Sheller code by the converter 13 and stored one by one in the error log table LLC. register 1 instead of code
Set to 5. The error code set in register 15 is displayed on display 1 in the same way as in normal display display operations.
There is no difference in that the data is converted into dont data corresponding to the light spot on the screen of No. 4 by a character generating section (not shown) and is scanned and displayed at, for example, 30 frames per second. On the other hand, when the operator operates the input unit 16 and inputs a designation to delete the displayed error code, the control unit 10 registers the error code in the all deletion registration table lid, as shown in FIG. 2(b). Furthermore, the error log table llc is accessed and, for example, 1 is recorded in a flag indicating that the error code has been designated to be deleted. Further, the control unit 10 sequentially goes back from the address of the error code, selects another error code that does not have a flag of 1, sets the selected error code in the register 15, and displays it on the display screen 14.

Here, the error log table llc is a storage area for error codes having n addresses, for example 256, as shown in Table 1, and the error code is always stored in the address FF next to the address where the previous error code was stored. Next, return to OO and write the -H error code and flag O' on top of the old error code, and write the 256 error codes specified for deletion registered in the deletion registration table lid mentioned above. It is assumed that a flag is written to 1 for the error code in the entire address range.

Table 1: Recording side of error log table lid After the operator recognizes the error code displayed on the screen of the display 14 and erases the input section 16 for a certain error code, as shown in FIG. 2(e) Then CP as shown in
Regarding the failure information manually inputted from U, each error code sent by the conversion unit 13 is recorded in the error log table lid, and the deletion registration table LLC is accessed and compared with the registered error code, and when they match. The error code disappears without being displayed.

If there is no matching registered error code, 1/Jister 1
0 displayed on the display 14 in place of the error code set to 5 and currently displayed. When access to the deletion registration table llc matches, a flag 1 is added to the corresponding record in the error log table lid. Also, since the error code to which a flag is added to the recorded content of the error log table LLC and the registered error code of the deletion registration table lid match in content, the n recording areas of the error log table LLC are set to be sufficiently large. For example, the daily amount can be covered by recording, and there is no problem even if the deletion registration error code ID is shared. If the control section 10 has a sub-digit capacity, the function of the conversion section 13 may be replaced with a part of the control section 10, and the storage area of the storage section 11 which also has the function of the register 15 may be used. It goes without saying that if necessary, the answers in the error log table 1idO can be displayed on the screen of the display 14 by separately specifying the recording order or the reverse j-row.

(g) As described in detail, according to the present invention, the display operation of the error log that has been designated for deletion is automatically removed by the operator's deletion designation, which is a drawback of conventional error log display methods. A useful error code display method with good operability is obtained in which error codes indicating severe failure information are not erased from the display due to frequent input of minor error codes.
