Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] Fig. 1 shows the system principle block diagram based on the method for retaining the system crash log on the POWER system through the BMC provided by the embodiment of the present invention. The method of retaining the crash log is described in detail in conjunction with the accompanying drawings as follows: The CPU sends the system log to the BMC in real time through the IPMI (Intelligent Platform Management Interface) protocol, and the BMC pre-allocates a piece of memory space for storing data from the CPU. system log. The memory space adopts a recycling strategy. When storing logs, the ...

Abstract

The invention discloses a method of retaining a system crash log on a POWER system through a BMC (boardmanagement control). A CPU (central processing unit) sends a system log to the BMC and stores the system log in the BMC in real time; the system log is prevented from being written into a Flash for storing BIOS (basic input and output system) FW(firmware), so that the BIOS FW damage risk can be avoided. The CPU sends the system log to the BMC through an IPMI (intelligent platform management interface) protocol. The BMC pre-allocates one memory space for storing the system log from the CPU. After the system crashing, the log before the system crashing can be checked on the BMC. According to the method, the system log is not directly stored into the Flash storing the BIOS FW; the system log is sent to the BMC through the IPMI protocol or other sending modes; the system log is stored into the pre-allocated memory space of the BMC or mounted external storage equipment; when the system crashes, the CPU sends the system log before the crushing to the BMC in real time, so that the all received system logs can be checked on the BMC; the BIOS FW damage risk is avoided.

Description

technical field [0001] The invention belongs to the technical field of server applications, and more specifically relates to a method for retaining system crash logs on a POWER (a server product name of IBM) system through BMC (Board Management Control). Background technique [0002] When the system crashes, the system log is written into the Flash storing the BIOS (Basic Input and Output System) FW (Firmware, firmware); the disadvantage of this prior art is that the Flash written by the system log is also The Flash of BIOS FW is stored, and there is a risk of damaging the BIOS FW when writing the Flash. Once the BIOS FW is damaged, the system cannot be started. Contents of the invention [0003] Aiming at the defects of the prior art, the purpose of the present invention is to provide a method for retaining the system crash log on the POWER system through the BMC, aiming to solve the problem in the prior art that the Flash written by the system log is also the storage of ...
