This test execution part is instructed to execute the test if the test table indicates it; but the faulty part us taken as the diagnosis result if the test table indicates it.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diagnostic system in an information processing device for diagnosing each part of the information processing device to identify a failure location.

[0002]

2. Description of the Related Art Conventionally, when a fault location of an information processing apparatus is diagnosed, a test program is executed, and when an error occurs as a result, raw information (status register from the hardware targeted by the test program is executed. Data) is displayed on a display or the like.

[0003]

However, in the diagnosis method as described above, in order to identify the faulty part of the information processing apparatus, the operator analyzes the test contents and the error information, You then have to decide which test to run and then perform some type of test to gather information. Therefore, such a method imposes a heavy burden on the operator, and there is a possibility that a difference may occur in the diagnosis result of the faulty part depending on the ability and experience of the operator.

From this point of view, there has been a demand for a diagnostic system in an information processing apparatus that reduces the burden on the operator and does not affect the operator's ability or experience on the failure location diagnosis result.

[0005]

In order to solve the above-mentioned problems, a diagnostic system in an information processing apparatus of the present invention is
To a plurality of test execution units that execute a test for detecting a failure location of the information processing device, a failure location for the test execution results of these test execution units, and the next test execution unit for the test execution results of the test execution unit When a fault table of the information processing device is diagnosed with the test table indicating the pointer of, the execution of each test execution unit is instructed using the test table, and the execution result is sent to the next test execution unit. When the pointer is indicated, the execution of the next test execution unit indicated is instructed, and when the execution result indicates the failure point, the diagnosis section which makes the failure point the diagnosis result is provided. It is characterized by that.

[0006]

In the diagnostic system of the information processing apparatus of the present invention, when the fault location of the information processing apparatus is diagnosed, the diagnostic section uses the test table to instruct the corresponding test execution section to execute the test. . As a result, the test execution unit executes the test, and the diagnosis unit receives the test execution result. Then, the diagnosis unit refers to the test table and obtains a pointer to the next test execution unit or a failure location corresponding to the test execution result. Here, if the test table indicates a pointer to the next test execution unit, an execution instruction is given to the indicated test execution unit,
When the failure point is indicated, the failure point is output as the diagnosis result.

[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 is a block diagram showing an embodiment of a diagnostic system in an information processing apparatus of the present invention. The system shown in the figure has a test program group 100 and a test table 20.
0, the diagnosis unit 300.

The test program group 100 is composed of a plurality of test execution units 100-1 to 100-n, and these test execution units 100-1 to 100-n start execution in response to a test execution instruction from the diagnostic unit 300. In addition, the execution result is sent to the diagnosis unit 300. Each of the test execution units 100-1 to 100-n is composed of a test program, for example, a memory test program or a DMAC test program.

The test table 200 shows the correspondence between the test execution results of each of the test execution units 100-1 to 100-n and the faulty part, and each test execution unit 100-1.
~ 100-n test execution results and the next test execution unit 1
It is a diagnostic information file showing pointers to 00-1 to 100-n.

FIG. 2 shows an example of the structure of the test table 200. Each test table is a table showing the correspondence between the next test table pointer for the end status as a result of the execution of the test and the failure point. For example, HD (hard disk) write read
In the compare test table, if the end status is a compare error, the next test table pointer is a memory test. On the other hand, if the end status is OK (no abnormality), the next test table pointer is E.
ND (no next test) and the failure location is NONE (no failure location).

Each of the test execution units 100-1 to 100-1
The execution order of 00-n has a tree structure, which is shown below. FIG. 3 shows each test execution unit 100-1 to 100-1.
It is explanatory drawing of the tree structure of the execution order of 0-n. Further, FIG. 4 is an explanatory diagram showing the execution ranges of the respective test execution units 100-1 to 100-n.

As shown in these figures, the test execution units 100-1 to 100-n have predetermined test execution orders, and when an error occurs during the execution of each test, the test execution units 100-1 to 100-n end the test execution order. From the status, test table 200
Based on, the failure location is identified. That is, the execution order is determined so as to expand the range of the test execution target from the main part to the peripheral part in the information processing apparatus.
The execution operation of each of the test execution units 100-1 to 100-n will be described in detail later. Also, in these figures, DMAC indicates a direct memory access controller, and SCSI indicates a small computer system interface.

When diagnosing each unit in the information processing apparatus, the diagnosis unit 300 gives an execution instruction to each of the test execution units 100-1 to 100-n based on the above-described test table 200, and also executes each test. Part 100-1 to 10
The test end result from 0-n is input, the test table 200 is referred to based on the test end result, and an execution instruction to the next test execution unit 100-1 to 100-n or a failure location is identified. It has a function to perform, and includes a test program starting unit 301, an execution result analyzing unit 302,
A fault location output unit 303 is provided.

Here, the test program starting unit 301
Is a test execution unit 100-1 to 100-n operated by an operator.
Or the test execution units 100-1 to 100-n start command generated by the execution result analysis unit 302,
The test execution units 100-1 to 100-n have a function of giving a start instruction.

The execution result analysis unit 302 acquires the execution results of the test execution units 100-1 to 100-n, refers to the test table 200, and generates a start command for a test to be executed next. As a result of referring to the test table 200, when the failure location is indicated, the failure location is provided as a diagnosis result.

Further, the fault location output unit 303 has a function of notifying the operator of the fault location output as the diagnosis result by the execution result analysis unit 302, and outputs a display signal or the like to be displayed on a display (not shown) or the like. It has a function to do.

Next, the operation of this embodiment will be described.
FIG. 5 is an operation flowchart of this embodiment. First,
When the operator inputs a start command to the system, the diagnosis unit 300 responds to the start command by
The test execution units 100-1 to 100-n are instructed to be executed (step S1). It should be noted that this execution instruction is an execution instruction to the test execution units 100-1 to 100-n that perform a test that includes all the operations of the module to be diagnosed.

As a result, the test execution units 100-1 to 100-n instructed to execute the corresponding tests (step S2) and output the result (= end status) of the test execution. Test execution units 100-1 to 100
The end status output from -n is analyzed by the execution result analysis unit 302 (step S3). That is, the execution result analysis unit 302 refers to the test table 200 and extracts the next test table pointer or the fault location corresponding to it.

Here, the next test table pointer is "E".
Whether or not the diagnosis is completed is determined depending on whether or not it is "ND" (step S4), and the next test table pointer is "EN".
If it is not "D", the diagnostic process is continued, and the start command of the next test table shown in that column is generated.
The corresponding test execution units 100-1 to 100-n are instructed to start up (step S5), and the process returns to step S2. On the other hand, in step S4, when the next test table pointer is “END”, the diagnosis process is completed, and thus the execution result analysis unit 302 sets the failure location name described in the failure location column as the analysis result. The failure point output unit 303 also displays this on a display or the like (not shown) (step S6).

Next, a specific example will be described with reference to FIGS. First, the diagnostic tree shown in FIG. 3 is a tree in which a certain test is associated with a test to be executed next depending on the execution result. For example, if a compare error occurs during the HD write / read compare test, a memory test is performed next, and the result of the execution also traces the tree to the bottom to find the fault location. Is. Then, in the creation of this tree, as shown in FIG. 4, it is necessary to model the hardware and sequentially expand the operation range of the test (the range of the hardware operated by the test). This allows
By expanding the range of hardware that guarantees normal operation, the location of the failure can be identified.

That is, in this embodiment, first, all elements (hardware to be diagnosed) in the information processing apparatus
If any error occurs in this test, the hardware that is guaranteed to operate normally will be expanded from the upper hardware to the lower hardware (main part to peripheral part). By doing so, the failure location is specified.

FIG. 2 is a diagram in which the diagnostic tree of FIG. 3 is converted into a data structure. For example, by using such a table, when a compare error occurs in the HD write / read compare test, the memory test is executed next, and further, “O” is executed in the memory test.
K ”,“ OK ”in the DMAC test, and when the status error occurs in the SCSI test, the faulty part is SCSI
Is specified.

In the above embodiment, the hardware to be diagnosed is the HD unit, SCSI, DMAC, and memory, but the hardware is not limited to this. Arbitrary diagnosis can be performed by setting the test table 200 so as to be specified.

As described above, in the diagnostic system for the information processing apparatus of the above embodiment, the test table indicates the next test table pointer and the failure point for the end status of the test execution unit, and the next test table pointer is the current time. Is configured to indicate a failure point when the end of the test is indicated, and the diagnostic section is pre-determined in order to expand the range of the test execution target from the main section to the peripheral section, Since the test execution unit is instructed to execute in accordance with this execution order, it is possible to easily identify the failure location and obtain an accurate diagnosis result. In addition, such a diagnostic system is highly effective especially when a maintenance person performs maintenance of the information processing device in the field.

[0025]

As described above, according to the diagnostic system of the information processing apparatus of the present invention, the test execution result and the pointer to the next test are shown as well as the correspondence between the test execution result and the fault location. Set up a test table,
When diagnosing each part, the test is executed based on the test table until the execution result indicates the failure point, so the burden on the operator can be reduced and the ability of the operator can be reduced. It is possible to obtain a diagnostic result that is not affected by or experience.
