Server system and crash dump collection method
Abstract:
There is provided a server system that collects memory information at the time of occurrence of a failure if a failure occurs in the operating system so as to enable failure analysis. Stall monitoring of a firmware is performed by hardware and, if a stall is detected, a reset is performed. A memory has a memory area used by a boot loader of the firmware and a memory area used by another part of the firmware. It is determined based on a reset factor retained in a device whether the reset is a normal reset or a reset associated with the stall detection. In the case where the reset is a reset associated with the stall detection, information of the memory area of the memory used by the another part of the firmware at the time of occurrence of the stall is collected.
