Abstract
To completely perform a memory data collecting process by a panic dump in the event of failure, in the configuration information about main memory 5 announced to an operating system by boot firmware, different areas (first main memory area and second main memory area) are set between activation of an operating system in a system operation mode and activation of an operating system in a dump operation mode. In the event of failure, activation is performed in the dump operation mode and a dumping process is performed with memory information in the event of failure maintained.
Claims19
A recording medium for recording a program used to direct a computer to perform a panic dump producing process, comprising:
- an area definition information obtaining process of obtaining a second area defintion information from an area defintion information unit storing the second area defintion information about a second area other than a first area used for an operating system mode designation information for control of an operation of the information processing device:
- an operating system storing process of storing an operating system in an area according to the second area defintion information;
- a dump target area calculating process of calculating as a dump target area a predetermined area in the first area corresponding to a predetermined area in an area according to the second area definition information;
- and
- a dumping process of reading and outputting information stored in the dump target area.
A panic dump producing method, comprising:
- an area definition information obtaining process of obtaining a second area definition information from an area definition information unit storing the second area definition information about a second area other than a first area used for an operating system that is an area of a storage unit of an information processing device according to an operation mode designation information for control of an operation of the information processing device;
- an operating system storing process of storing an operating system in an area according to the second area definition information;
- a dump target area calculating process of calculating as a dump target area a predetermined area in the first area corresponding to a predetermined area in an area according to the second area definition information;
- and
- a dumping process of reading and outputting information stored in the dump target area.
