Abstract

PURPOSE:To prevent the fault state of a mainframe system computer from being continuously left as it is by permitting the mainframe system computer to report that it has fallen into an unoperable state due to a fault in a system control processor itself when it occurs. CONSTITUTION:When the system control processor 102 executes the critical state control of the mainframe system computer 101, a display F/F 106 showing that the system is under critical processing is set under the recognition of software. When the fault has been detected in a fault detection and report part 105, a condition is taken in the output of critical processing display F/F 106 and an AND gate 107, namely, while the system control processor 102 processes a critical state and when the fault occurs in the system control processor itself, it is reported to an operator station 103 through an unoperable state report line 109. Thus, the mainframe system computer 101 is prevented from being left as it is without being recognized that it is in the fault state, and the enlargement of a damage can be avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an independent system control processing device that executes fault handling and state control of a computer, and particularly, the present invention relates to an independent system control processing device that executes failure processing and state control of a computer, and in particular, This paper relates to a failure reporting method when a failure occurs in the system control processing unit itself while executing control. [Prior Art] Conventionally, the function of a system control processing unit is to handle failures in the main system computer. In other words, when a failure occurs in the main system computer, it performs processing such as collecting information about the failure location and restarting the system. In addition, the system control processing unit is in an independent relationship with the main body computer, so that failures that occur within the system control processing unit do not adversely affect the main body computer, except when the main body computer is processing a critical state. Therefore, normal operation of the main system computer can continue normally. At this time, only failures in the system control processing unit are reported to the operator. This report allows the operator to recognize that the main body computer is operating normally, but that the system control processing unit is inoperable.

However, this system control processing unit is executing control of transient states such as start-up control, configuration control, and fault handling control of the main body computer, and especially critical state control that is extremely unstable for the main body computer. For example, if you are managing computer configuration information, collecting failure information in the event of a failure, or controlling information that has great significance in determining the operating status, such as communicating important information, it is difficult to determine the status of the main computer. The control is entrusted to the system control processing unit, and if a failure occurs in the system control processing unit at such times, the status of the main system computer cannot be guaranteed, which is extremely fatal. In this case, the main system computer will not be able to perform restart processing and will become inoperable. However, at this time, the system control processing unit that handles failure processing for the main body computer is inoperable due to a failure, and only the failure of the system control processing unit is reported to the operator, and failures of the main body computer cannot be reported. ．． [Problem to be solved by the invention] As mentioned above, if a failure occurs in the system control processing unit itself while processing a very critical state of the main body computer, the main body computer will become inoperable. However, only failures in the system control processing unit are reported to the operator, and failure conditions in the main system computer are not reported. That is, there is a problem in that the main computer appears to be operating normally, and is left unrecognized without being recognized as being in a faulty state. In order to avoid further damage such as memory corruption and inoperability affecting users, failure conditions must be promptly reported.

[Means to solve the problem]

The fault reporting method of the present invention provides a system control processing device that collectively executes fault processing and state control processing of a computer to control an unstable critical state in which the operating state of the computer is not determined. critical processing display means for displaying that processing is in progress; failure detection reporting means for detecting and reporting a fault in the system control processing unit; and critical processing display means for indicating that the computer is in critical state. and inoperable state reporting means for reporting that the computer has fallen into an inoperable state when a fault in the system control processing unit is detected by the fault detection reporting means. [Example] The present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing one embodiment of the present invention. In the figure, a system control processing device (
DGP) 102 is a system control processing unit 102 other than when the main body computer 101 is processing a critical state.
The failure is an independent device that does not affect the normal operation of the main computer 101. The system control processing unit 102 sets and cancels the critical processing display F/F 106, which indicates that the critical state of the main body computer 101 is being processed, and the critical processing display F/F 106. Display setting control 1

F/F10 before executing critical state control in step 1.
6 is set and cleared after execution to indicate that critical processing is in progress. Furthermore, it has a failure detection and reporting section 105 that detects failures within the system control processing unit 102 and reports them to the operator station 103. The system control processing unit 102 is the main body computer 10
If critical processing 1 is not performed, a fault in the system control processing unit 102 detected by the fault detection reporting section 105 is reported to the operator station 103 via the fault reporting line 108. The operator station 103 receives this report and displays it to the operator. This does not affect the normal operation of the main computer 101 in any way. The system control processing unit 102 is the main body computer 10
When performing critical state control 1, the critical processing display F/F 1 0 6 is set in advance with software recognition. Failure detection reporting unit 10
If a failure is detected in 5, the critical processing display F/
If a condition is established between the output of F 1 0 6 and the AND gate 107, that is, the system control processor 102 is processing a critical condition and a failure occurs in the system control processor itself, the inoperable condition report line 109 is output. and report to operator station 103. In this case, the system control processing unit 102 is in a failure state, and it is impossible to carry out troubleshooting for the failure of the main body computer 101 caused by this, but at least the operator can be notified that the main body computer 101 has fallen into an inoperable state. You can report it. As described above, it is reported to the operator that the main body computer 101 has fallen into an inoperable state due to a failure that occurred in the system control processing unit 102 while the main body computer 101 is processing a critical state.

〔Effect of the invention〕

As explained above, in the present invention, when a failure occurs in the system control processing unit itself that is processing a very critical state of the main body computer, this causes the main body computer to become inoperable. By reporting this to the operator, it is possible to prevent the failure state of the main system computer from continuing to go unrecognized, which has the effect of suppressing the spread of damage.
