Abstract

The embodiment of the invention discloses a device and a method for backing up Control Device firmware by using BMC Flash, the device comprises a starting module, a control module and an upgrading module, the starting module is connected with the control module and the upgrading module, and the upgrading module is connected with the control module; wherein the starting module is used for startinga server, the upgrading module is used for firmware upgrading, and the control module is used for switching between firmware starting and firmware upgrading; the method comprises the steps that firmware to be upgraded is temporarily stored in a BMC RAM; the BMC checks whether the signature and content of the firmware to be upgraded in the RAM are correct or not; if the upgraded firmware passes theinspection, outputting a firmware difference gear before and after upgrading; the BMC writes the firmware difference file into a Backup flash; the BMC writes the firmware to be upgraded, which is temporarily stored in the RAM, into a Device flash; and starting the server by using the upgraded firmware by the Control Device. According to the method of the invention, the problems that the functionand the capacity of Device flash in the existing Contourler Device firmware backup circuit are limited, the circuit is complex, and the occupied board card space is large are solved.

Description

technical field [0001] The invention relates to the technical field of BMC control, in particular to a device and method for backing up ControllerDevice firmware by using BMC Flash. Background technique [0002] The firmware upgrade of the device on the server can generally be achieved through IPMI (IPMI, Intelligent Platform Management Interface, Intelligent Platform Management Interface) OEM commands. However, due to the limited Flash memory capacity of the BMC itself, the BMC will not actively back up the original firmware used by the peripheral Controller Device unless the peripheral Controller Device has designed redundant EEPROM / flash memory. Even if the device has a redundant design, it is usually only allowed to keep the latest firmware image. [0003] Such as figure 1 As shown, it is a block diagram of the hardware structure of the current backup Controller Device firmware using BMC Flash. When the server starts normally, the Controller Device connects to Device f...
