fig. 2 is a schematic structural diagram of a server according to an embodiment of the present invention.
Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the problems that the existing BIOS refreshing mode is easily affected by various unpredictable interference factors and hardware platform limitation, so that the BIOS refreshing mode fails in refreshing and cannot be restarted after refreshing operation, the invention provides a BIOS refreshing control solution which is not affected by the interference factors, is not limited by the hardware platform, has strong transportability and is low in cost.
Example one
Referring to fig. 1, the present embodiment provides a BIOS refresh control method, including the steps of:
In the step, the BIOS program is refreshed and controlled in an out-of-band management mode. Out-of-band management, i.e. management control information and data information are transmitted through different physical channels, and the control plane and the data plane are completely independent and do not affect each other. By adopting the out-of-band management mode, the BIOS program can be controlled through the control plane channel when running, namely, business processing is carried out through the data plane channel.
The BMC module, i.e. out-of-band management software, may manage the service system, such as managing a service power supply (power on or power off, etc.), providing a remote KVM (Keyboard, display, Mouse) function, and providing a mirror image mount function to facilitate a user to manage the service system; the BMC module may also manage hardware of the device, for example, monitor operating states of a CPU (Central Processing Unit), a memory, a hard disk, and a network card, so as to discover an abnormality in time; in addition, the BMC module may also provide various user interfaces for a user to manage the device through out-of-band management software, such as WEB, SSH, and FTP based interfaces.
Currently, the BMC module can manage power up and down, temperature, speed regulation, alarms, fault diagnosis, and the like. When the BMC module manages the BIOS, the BMC module may communicate with the BIOS through a Low Pin Count (LPC) interface to monitor states of the BIOS and a service system in a power-on process; or, the firmware can also be communicated with the BIOS solidified in the SPI Flash chip through an SPI (Serial peripheral interface), and the firmware of the BIOS solidified in the SPI Flash can be upgraded after the read-write permission is acquired.
The online update operation in this step may be performed in a conventional manner, and this embodiment is not limited.
And 102, after the online updating operation is finished, the BMC module sends a power-off instruction to the CPLD module.
The power-off instruction is used for instructing the CPLD module to perform power-off operation on the PCH. Illustratively, the power-down instruction may be an SGPIO signal, specifically, a high-level signal or a low-level signal.
And 103, after the CPLD module receives the power-off instruction, controlling all PCHs to be powered off.
And 104, after controlling all power-off of the PCH, the CPLD module waits for a preset time length and then controls the server to start.
Because the whole power-off of the PCH needs a certain time, in order to ensure that the PCH can be completely powered off to ensure that a subsequent server can be normally started, the step adopts time delay control on the starting operation. For example, the preset time period may be 1-5 seconds.
In summary, the embodiment of the present invention adopts a way that the BMC module directly performs online update operation on the BIOS file when the server is in a shutdown state, thereby reducing the step of setting the ME to recovery mode before update operation, completely eliminating interference of various unpredictable interference factors on the step of setting the recovery mode, removing the limitation of a hardware platform, improving portability, and ensuring smooth online update operation.
In addition, when the updating operation is finished, the BMC module sends the SGPIO protocol signal to the CPLD module to inform the CPLD to control the PCH to be completely powered off, so that the complete power failure of the PCH can be effectively ensured, and the smooth execution of the server restarting operation is ensured.
Example two
Correspondingly, referring to fig. 2, the second embodiment provides a server, including: a BMC module and a CPLD module.
The BMC module is used for carrying out online updating operation on the BIOS file after receiving the refreshing instruction in the shutdown state of the server; the power-off instruction is also used for sending a power-off instruction to the CPLD module after the online updating operation is finished;
the CPLD module is used for controlling the PCH to be powered off completely after receiving the power-off instruction; and the system is also used for waiting for a preset time length and then controlling the server to start after the PCH is controlled to be completely powered off.
The BMC module and the CPLD module can be connected by adopting an SGPIO bus, and the power-down command is an SGPIO signal and can be selected as a high-level signal or a low-level signal. Of course, other signals may be used for the power-down command, and the invention is not limited.
In summary, the BMC module in the embodiment of the present invention performs refresh control on the BIOS program in an out-of-band management manner, and on this basis, the BMC module in the embodiment of the present invention automatically triggers the CPLD to power off the PCH after the online update operation is completed, which can effectively ensure complete power off of the PCH and ensure smooth execution of the server restart operation.
