Program, method, and mechanism for performing panic memory dump

摘要

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 (S210) and activation of an operating system in a dump operation mode(S209). In the event of failure, activation is performed in the dump operation mode and a dumping process(S408) is performed with memory information in the event of failure maintained.
