step S101: judging whether an upgrading instruction for starting the BIOS firmware to upgrade is received or not according to the operation of a Smshclp system interface of the BMC; if yes, go to step S102;
in one embodiment, the instruction can be sent through a Smshclp system of the BMC without an account number and a password, and the BMC is controlled to perform corresponding operation. Therefore, when the BIOS firmware needs to be upgraded, whether an upgrade instruction for starting the BIOS firmware to upgrade is received or not can be judged according to the operation of an operation and maintenance person on a Smshclp system interface of the BMC. If yes, the BIOS firmware can be upgraded according to the upgrading instruction.
Step S102: acquiring file information of an upgrade file of the BIOS firmware contained in the upgrade instruction;
step S103: and according to the file information, acquiring an upgrade file to upgrade the BIOS firmware.
In specific implementation, the upgrade instruction includes file information of an upgrade file of the BIOS firmware. Specifically, the file information specifically includes an Internet Protocol (IP) address, a port number, and a file name of the upgrade file of the file server storing the upgrade file. In one embodiment, an HTTPS file server may be established and the BIOS firmware upgrade file placed under the HTTPS file server directory. And then, acquiring an upgrade file according to the file information, storing the acquired upgrade file into a BMC memory, and upgrading the BIOS firmware.
In one embodiment, acquiring the upgrade file to upgrade the BIOS firmware according to the file information specifically includes:
establishing communication connection with a file server for storing the upgrade file according to the IP address and the port number in the file information;
and acquiring a file with a file name from the file server as an upgrade file.
Specifically, the communication connection between the BMC and the file server may be established according to the IP address and the port number of the file server storing the upgrade file, so that the BMC may obtain the file stored in the file server. And according to the file name of the upgrade file recorded in the file information, searching files with the same file name in a file server directory to obtain the upgrade file.
In one embodiment, the obtaining the upgrade file to upgrade the BIOS firmware specifically includes:
and acquiring a compressed file corresponding to the upgrade file, and decompressing the compressed file according to a preset decompression algorithm to acquire the upgrade file.
Specifically, when the storage space occupied by the upgrade file is large, the upgrade file is generally compressed and stored in the form of a compressed file. In order to ensure the transmission efficiency of the file, the compressed file corresponding to the upgrade file can be directly obtained, and the decompression operation is carried out on the compressed file according to a preset decompression algorithm, so that the upgrade file is obtained. It should be noted that the preset decompression algorithm is specifically a decompression algorithm corresponding to a compression algorithm adopted when the upgrade file is compressed.
In one embodiment, the obtaining the upgrade file to upgrade the BIOS firmware specifically includes:
and acquiring an encrypted file corresponding to the upgrade file, and decrypting the encrypted file according to a preset decryption algorithm to acquire the upgrade file.
Specifically, in order to ensure the security of the transmission of the upgrade file, the file server encrypts the upgrade file in advance to obtain an encrypted file corresponding to the upgrade file. The BMC may obtain the encrypted file first and perform a decryption operation on the encrypted file according to a preset decryption algorithm to obtain the upgrade file. It should be noted that the preset decryption algorithm is specifically a decryption algorithm corresponding to the encryption algorithm used when the upgrade file is encrypted.
The invention provides a BIOS firmware upgrading method, which comprises the following steps: judging whether an upgrading instruction for starting the BIOS firmware to upgrade is received according to the operation of an operation and maintenance person on a Smshclp system interface of the BMC; if yes, acquiring file information of an upgrade file of the BIOS firmware contained in the upgrade instruction; and according to the file information, acquiring an upgrade file to upgrade the BIOS firmware. Therefore, the upgrading operation of the BIOS firmware is carried out through the received upgrading instruction sent by the Smshclp system, and the Smshclp system can complete information interaction in a mode of directly inputting the instruction, so that operation and maintenance personnel can directly complete the sending operation of the upgrading instruction on the Smshclp system interface without an account number and a password, and the condition that the account number and the password are input in a system interface provided by a client is avoided. The upgrading process of the BIOS firmware is simpler, unnecessary time and resource waste are reduced, and the upgrading efficiency is improved. The use risk caused by untimely upgrade is reduced as much as possible, and the use experience of the client is improved.
In one embodiment, the method for upgrading BIOS firmware provided by the present invention further includes:
judging whether an upgrading script of the BIOS firmware is integrated in the stored BMC mirror image;
if not, an alarm prompt is made to indicate that the BIOS firmware is temporarily unavailable.
Specifically, after the BIOS firmware is upgraded, the related operations of the BIOS firmware are required to be operated according to the requirements of the upgraded BIOS firmware, so that the upgrade script of the BIOS firmware needs to be integrated in the BMC image to ensure that the BIOS firmware can normally work subsequently. In order to confirm whether the upgraded BIOS firmware can work normally, whether an upgrade script of the BIOS firmware is integrated in the stored BMC image or not can be judged, if not, the upgraded BIOS firmware is not supported to work normally under the current condition, the BMC image needs to be configured in advance, and an alarm prompt can be given to indicate that the BIOS firmware cannot be used temporarily, so that operation and maintenance personnel can find and process problems in time; and if the judgment result is that the upgrading script is integrated, the BIOS firmware after upgrading can be normally used.
In an embodiment, the method for upgrading BIOS firmware provided in the embodiment of the present invention further includes:
judging whether an updating instruction for updating the upgrading file is received or not;
and if so, updating the upgrade file according to the update instruction.
In particular, typically the BIOS firmware needs to be continually upgraded and updated to provide better service to the user. Therefore, the upgrade file of the BIOS firmware also needs to be updated continuously, whether an update instruction for updating the upgrade file is received can be determined, and if so, the upgrade file can be updated according to the update instruction. Specifically, the latest upgrade file of the BIOS firmware of the latest version may be obtained according to the update instruction and stored in the memory of the BMC.
Further, the method for upgrading the BIOS firmware provided in the embodiment of the present invention further includes:
judging whether a history upgrading file of the BIOS firmware is stored in the memory;
and if so, deleting each history upgrading file.
In specific implementation, in order to ensure effective utilization of the BMC memory, the history update file of the history version stored before may be deleted, so as to increase the remaining space of the BMC memory. The files stored in the BMC memory can be detected at regular time, and when the historical upgrading files are judged to be stored in the memory, the deletion operation is correspondingly carried out.
The invention also provides an upgrading device of the BIOS firmware and a corresponding embodiment of the upgrading device of the BIOS firmware.
