Abstract

PURPOSE:To collect information without missing, by holding a collecting method of fault information in every main frame device in the form of a list, and allowing a monitoring device or an SVP to refer to the list and collect the fault information. CONSTITUTION:If a fault occurs to a main frame device 1-0, the device 1-0 causes an interruption to the SVP3 through a fault interruption line 6. A program module 9 of the SVP3 is activated by the interruption to discriminate the device 1-0 being in the faulty state. A program module 13, on the other hand, sets a latch address where information to be collected is held in a selecting circuit 12 to collect fault information on the main frame device 1-0 through an AND circuit 15-0, and the program module 13 processes it. Thus, the collected information is displayed on a display and reported to an operator.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention provides a system for collecting and processing fault information, particularly a monitoring device or a service processor (hereinafter abbreviated as SVP) that automatically performs automatic processing in response to an interrupt from a faulty device. The present invention relates to a fault information collection processing method that logs fault data automatically.

(2) Technical Background and Problems Traditionally, in relatively large-scale data processing systems, SvPs are created outside the main unit, such as main storage, central processing units, channels, etc. It is designed to monitor failures, etc. In response to a failure of the main unit, the system is configured to collect failure information from the failed device in response to an instruction from an operator.

However, in the conventional configuration, in response to a failure, a diagnostic command is given to the SVP by an operator's instruction, and based on this, the SVP scans out information in the failed device. For this reason, the operator may forget to acquire the fault information, and there may also be a situation where the fault information cannot be collected due to incorrect judgment by the operator.

(3) Object and Structure of the Invention The entire object of the present invention is to solve the above-mentioned objects, and the fault information collection and processing method of the present invention includes at least a main storage device, a central processing unit, a channel, and a monitoring system. In a data processing system in which a device or service processor monitors the system for failure conditions, a device is provided between the monitoring device or the service processor corresponding to the main storage device, central processing unit, and channel, respectively. ,
In addition to providing a fault interrupt line, an address information line for collected data, and a bus line for collected data, the monitoring device or service processor includes a fault device identification program module, a fault interrupt line, and a fault interrupt line provided in response to an interrupt from the fault interrupt line. The above-mentioned monitoring device or service is equipped with a selection register corresponding to the device and emitting a selection signal for selecting a faulty device, and a fault information collection program module that collects fault information in a form corresponding to the faulty device. The processor is characterized in that it determines the faulty device in response to an interrupt from the faulty interrupt line, and then collects fault information from the faulty device. This will be explained below with reference to the drawings.

(4) Embodiment of the Invention FIG. 1 shows an embodiment of a data processing system to which the present invention is applied, and FIG. 2 shows an embodiment in which a mode of failure information collection by SVP is illustrated in an explanatory diagram.

In the figure, 1 is the main unit that corresponds to the main memory, central processing unit, and channels; 2 is the system interface; 3 is the monitoring device or service processor; 4
is a display device, 5 is an information recording device, 6 is a fault interrupt line, 7
1 is an address information line for collected data, 8 is a bus line for collected data, 9 is a faulty device identification program module, 10 is a faulty device extractor, 11 is a faulty device selection register, 12 is a latch selection circuit for data collection, and 13 is a data collection latch selection circuit. Fault information collection program modules 14 and 15 each represent an AND circuit.

Between each main unit 1-0 to 1-5 and 5VP3,
A fault interrupt line 6, an address information line 7 for collected data,
A collected data bus line 8 is provided in parallel, so to speak. On the other hand, 5VPa includes program number modules 9 and 13, as well as a faulty device selection register 11.
is configured such that address information can be set in the data collection latch selection circuit 12 according to instructions from the program module 13.

When a failure occurs in one of the main devices, for example 1-0, 5VP3 is sent from the device 1-0 via the failure interrupt line 6.
An interrupt is issued for. In 5VP3, the program module 9 is activated based on this, and the #0 portion in the register 11 is set to logic "1" in order to select the faulty device 1-0 via the faulty device extractor 10.

On the other hand, the program module 13 executes the faulty device f.
Failure information is collected in a format corresponding to 1-0. That is,
Set the address for the latch in which the information to be collected is held in the selection circuit 12, access the latch in the faulty main unit 1ft-o via the AND circuit 14-0, and set the contents of the latch to the AND circuit. 15-
The information is collected by the program module 13 via o, and then collected by the information recording device 5. That is, main device 1-0
The contents of all the latches or the main latches are sequentially collected and recorded, and the operator is notified of this through the display device 4. Needless to say, such records are edited to summarize mutually related information.

When executing processing by the program module 13, the address of the latch to be scanned out, the editing format of the collected data, etc. are compiled into a list for each main device and stored on a disk, for example. When it is determined, the program module 13 executes the collection process with reference to the restructuring. Of course, the same list is used for main devices of the same type.

(5) As described in detail, according to the present invention, when a failure occurs, the monitoring device or SvP can automatically collect and record failure information. This prevents failure information from being forgotten or collected incorrectly. In addition, the program module 13 is largely independent of each main unit, as it is maintained in the form of a list and referenced as to how fault information is collected for each main unit. It is possible to prepare in this way.
