Abstract

PURPOSE:To evade the fault occurred while loading a program by checking whether load processing is normally performed by a disk device control adapter or not, thereby taking countermeasures based on the contents of recorded error information generated while loading the program. CONSTITUTION:A disk device control adapter 100 is provided with a loader means A, an error detecting means B to check whether error is generated during loading with the loader means or not, an error recording means C to record error information detected by the error detecting means in a main memory 300, and a disk control means D to control these respective mean. Then, the loader means reads a load object program 21 from a fixed disk device 20 through the disk control means and transfers it to a load program storage area 31 of the main memory 30. At such a time, the error detecting means checks whether load processing is normally performed or not.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an error information collecting device, and more particularly to an error information collecting device suitable for starting up a data processing device.

[0002]

2. Description of the Related Art The conventional collection of error information when starting up a data processing apparatus has been provided as a function of an operating system.

The operating system retries if an error occurs while loading the program, and continues loading when the error is resolved.

[0004]

However, in the above-mentioned conventional example, since the error information during the loading of the program is not recorded, it is impossible to prevent or avoid the failure occurring during the loading, and the system There was an inconvenience that the operation could not be started.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to improve the inconvenience of the conventional example, particularly to record error information generated during the loading of a program, and to take preventive measures based on the content of the error information. An object of the present invention is to provide an error information collecting device capable of avoiding a failure that occurs during loading.

[0006]

Therefore, according to the present invention, a fixed disk device storing a program, a main memory storing the program and error information, and a program are loaded from the fixed disk device to the main memory. In addition, a disk device control adapter for performing error processing during loading and recording error information in the main memory is provided. This aims to achieve the above-mentioned object.

[0007]

When the data processing device is powered on, the disk device control adapter reads the load target program from the fixed disk device and transfers it to the load program storage area of the main memory. At this time, the disk device control adapter checks whether or not the loading process has been performed normally.

When there is an error in the area of the fixed disk device which stores the program to be loaded, the disk device control adapter executes the reading from the fixed disk device again. On the other hand, if there is an error in the area of the main memory that stores the program to be loaded, the disk device control adapter executes writing to the main memory again.

At the same time, the disk device control adapter stores retry information such as the number of retries, error address, and avoidance method in the error information storage area of the main memory.

When the loading of the program is completed and the operating system starts up, the operating system reads the contents of the error information storage area of the main memory, processes it into the same format as the system error log, and stores the logging data of the fixed disk device. Store in area.

By using the logging data analysis tool of the operating system, the contents of the error log stored in the logging data storage area of the fixed disk device are analyzed, and the fixed disk device storing the load target program is analyzed. You can know if there is an error in the area.

At this time, if there are many retries during startup, the area for storing the load target program is changed to an error-free area.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to FIG. In the embodiment shown in FIG. 1, a fixed disk device 20 storing a program, a main memory 30 storing a program and error information, a program being loaded from the fixed disk device 20 to the main memory 30 and being loaded. Disk device control adapter 1 for performing error processing and recording error information in the main memory 30
It consists of 0 and.

Here, the disk device control adapter 10
Is a loader means 14 for loading the load target program 21 stored in the fixed disk device 20 into the main memory 30, and an error detection means 12 for checking whether an error has occurred during loading by the loader means 14.
And a retry means 13 for retrying when an error is detected by the error detection means 12, and an error detection means 1
An error recording unit 15 for recording the error information detected in 2 in the main memory 30 and a disk control unit 11 for controlling each unit are provided.

Next, the operation of this embodiment will be described.
When the data processing device (not shown) is powered on, the disk control means 11 activates the loader means 14.

The loader means 14 is a disk control means 11
The load target program 21 is read from the fixed disk device 20 via the, and transferred to the load program storage area 31 of the main memory 30. At this time, the error detecting means 12 checks whether or not the loading process has been normally performed.

(1) When there is an error in the area of the fixed disk device 20 storing the load target program 21:

The error detecting means 12 is a retry means 13
Is started and the error recording means 15 is notified.

The retry means 13 operates the loader means 14 to execute reading from the fixed disk device 20 again.

The error recording means 15 stores retry information such as the number of retries, error address, and avoidance method in the error information storage area 32 of the main memory 30.

When the loading of the program is completed and the operating system starts up, the operating system reads the contents of the error information storage area 32 of the main memory 30 and processes it into the same format as the system error log, and the fixed disk unit 20 of The data is stored in the logging data storage area 22.

Then, by using the logging data analysis tool of the operating system, the contents of the error log stored in the logging data storage area 22 of the fixed disk device 20 are analyzed, and the fixed program storing the load target program 21 is analyzed. It is possible to know whether there is an error in the area of the disk device 20.

At this time, if there are many retries during startup, the area of the fixed disk device 20 for storing the load target program 21 is changed to an error-free area.

(2) If there is an error in the area of the main memory 30 that stores the load target program 21:

The error detecting means 12 is a retry means 13
Is started and the error recording means 15 is notified.

The retry means 13 activates the loader means 14 to execute writing to the main memory 30 again.

The error recording means 15 stores retry information such as the number of retries, error address, and avoidance method in the error information storage area 32 of the main memory 30.

When the loading of the program is completed and the operating system is started up, the operating system reads the contents of the error information storage area 32 of the main memory 30 and processes it into the same format as the system error log, and the fixed disk unit 20 of The data is stored in the logging data storage area 22.

Then, by using the logging data analysis tool of the operating system, the contents of the error log stored in the logging data storage area 22 of the fixed disk device 20 are analyzed and the main memory 30 for storing the load target program 21 is analyzed. You can see if there is an error in the area.

At this time, if there are many retries during startup, the area of the main memory 30 for storing the load target program 21 is changed to an error-free area.

[0031]

Since the present invention is constructed and functions as described above, it is possible to record error information generated during the loading of a program and take preventive measures based on the contents of the error information. It is possible to provide an unprecedented excellent error information collecting device capable of avoiding a failure that occurs during the loading of a program.
