All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The core of the embodiment of the invention is to provide a method for modifying server parameters, which can improve the convenience of modifying the server parameters; another core of the present invention is to provide a device, apparatus and computer readable storage medium for modifying server parameters, which have the above advantages.
In order that those skilled in the art will better understand the present invention, the following description of the present invention will be taken with reference to the accompanying drawings and detailed description.
Fig. 1 is a flowchart of a method for modifying server parameters according to an embodiment of the present invention. As shown in fig. 1, a method for modifying server parameters is applied to a BMC, and includes:
s10: and acquiring server parameters of the target server, and writing the server parameters into a preset memory.
Specifically, in this embodiment, the operator may input server parameters through IPMI tool or BMC web, and the BMC may obtain corresponding server parameters by receiving data information input by the operator; after the BMC acquires the server parameters, checking whether the format of the server parameters accords with the standard format, and storing the server parameters in a preset memory under the condition that the format accords with the standard format. In practice, the preset memory is typically a memory in the BMC, such as an EEPROM (Electrically Erasable Programmable read only memory ).
S20: when the target server is restarted to run to the hostboot stage, receiving an acquisition request for acquiring server parameters, which is sent by the PONR;
s30: and reading the server parameters from a preset memory according to the acquisition request, and sending the server parameters to the PNOR so that the PNOR writes the server parameters into the corresponding target registers.
After the BMC stores the server parameters in the preset memory, the target server is restarted. When the target server restarts to run to the hostboot stage, receiving an acquisition request for acquiring server parameters, which is sent by the PONR; and reading the server parameters from a preset memory according to the acquisition request. Specifically, after receiving an IPMI command input by an operator, the BMC obtains pre-stored server parameters from a preset memory according to the IPMI command, generates corresponding response information, and feeds back the response information according to the IPMI command. The IPMI command may be set according to actual requirements, and the specific content of the IPMI command is not limited in this embodiment.
After acquiring the server parameters from the preset memory according to the acquisition request sent by the PNOR, the BMC sends the server parameters to the PNOR, the PNOR sets the server parameters in the corresponding target memories after receiving the server parameters, and the updated server parameters, namely the server parameters, are used to take effect when the target registers are operated.
In addition, it should be noted that, in this embodiment, the server parameter of the target server can be modified by using the BMC, that is, the server parameter is modified out of band, and for the prior art, the convenience of modifying the server parameter by the operation and maintenance personnel is further improved in the mode that the server parameter can only be modified in band generally.
According to the server parameter modification method provided by the embodiment of the invention, firstly, the server parameters of a target server are obtained through the BMC, and the server parameters are written into a preset memory; then when the target server is restarted to run to the hostboot stage, receiving an acquisition request for acquiring server parameters sent by the PONR; and reading the server parameters from a preset memory according to the acquisition request, and sending the server parameters to the PNOR so that the PNOR writes the server parameters into corresponding target registers, thereby realizing the modification of the server parameters of the target server. In the method, the modification of the server parameters can be realized by only editing the server parameters in a data calling mode, and compared with the mode of modifying the server parameters by using an in-band tool pflash in the prior art, the operation process is more convenient.
On the basis of the above embodiment, the present embodiment further describes and optimizes the technical solution, and specifically, in this embodiment, the process of obtaining the server parameter of the target server and writing the server parameter into the preset memory specifically includes:
obtaining server parameters of a target server;
calculating a check value of the server parameter;
writing the server parameters and the check values into a preset memory;
correspondingly, after reading the server parameters from the preset memory according to the acquisition request, the method further comprises:
and verifying whether the check value is accurate, and if so, entering a step of sending the server parameter to the PNOR so that the PNOR writes the server parameter into a corresponding target register.
Specifically, in this embodiment, after obtaining the server parameter of the target server, the BMC further calculates the check value of the server parameter, and writes the server parameter and the corresponding check value into the preset memory. In actual operation, the method of calculating the check value of the server parameter may be to calculate the corresponding hash value as the corresponding check value by a hash algorithm, or may calculate the corresponding check value by a CRC algorithm, which is not limited in this embodiment.
As a preferred embodiment, the process of calculating the check value of the server parameter is specifically:
a CRC check value of the server parameter is calculated.
It should be noted that in this embodiment, it is preferable to calculate the corresponding CRC check value according to the server parameter, and write the server parameter and the corresponding CRC check value into the preset memory. It can be understood that the CRC check value, that is, the cyclic redundancy check code CRC, is abbreviated as cyclic code, which is a commonly used check code having the capability of error detection and error correction.
Correspondingly, when the target server restarts to operate to the hostboot stage, after receiving an acquisition request for acquiring the server parameters sent by the PONR, the BMC reads the server parameters from the preset memory according to the acquisition request and further verifies whether the check value is accurate or not, specifically, the check value acquired from the preset memory is compared with a preset standard check value, and if the check value is consistent with the preset standard check value, the check value stored in the preset memory is accurate. Under the condition that the check value is accurate, the method enters a step of sending the server parameter to the PNOR so that the PNOR writes the server parameter into a corresponding target register; if the check value is inaccurate, the invalid value is responded.
Therefore, in this embodiment, by further calculating the corresponding check value for the server parameter, and storing the server parameter and the corresponding check value in the preset memory, when the server parameter is obtained from the preset memory, the integrity of the server parameter is verified according to the check value, so that the availability and reliability of the server parameter set for the target server can be further ensured.
As a preferred embodiment, the process of writing the server parameter into the corresponding target register by the PNOR specifically includes:
PNOR verifies the validity of the server parameters and writes the server parameters into the corresponding destination registers if verification passes.
After the PNOR acquires the server parameters from the BMC, further verifying the validity of the server parameters, wherein the verification of the validity may include the source of the server parameters, whether the server parameters carry digital certificates, etc., and if the verification passes, the PNOR writes the server parameters into the corresponding target registers; if the verification is not passed, ending the modification flow of the server parameters.
That is, the modification method of the server parameter in this embodiment further verifies the validity of the server parameter before the PNOR writes the server parameter into the corresponding target register, thereby further guaranteeing the security of the target server.
On the basis of the above embodiment, the technical solution is further described and optimized in this embodiment, and specifically, after the server parameter is read from the preset memory according to the acquisition request, and the server parameter is sent to the PNOR, so that the PNOR writes the server parameter into the corresponding target register, this embodiment further includes:
and sending out corresponding prompt information.
Specifically, in this embodiment, after the server parameter is read from the preset memory according to the acquisition request, and the server parameter is sent to the PNOR, so that the PNOR writes the server parameter into the corresponding target register, the prompting device is further triggered to send corresponding prompting information. It should be noted that, the prompting device may be specifically a buzzer and/or an indicator light and/or a display, and the corresponding prompting information, such as a buzzer/a flashing light/a text or an image, is sent out by triggering the prompting device such as the buzzer/the indicator light/the display, so as to intuitively prompt the operation and maintenance personnel that the modification of the server parameter of the target server is completed at present, thereby further improving the use experience of the user.
On the basis of the above embodiment, the technical solution is further described and optimized in this embodiment, and specifically, after the server parameter is read from the preset memory according to the acquisition request, and the server parameter is sent to the PNOR, so that the PNOR writes the server parameter into the corresponding target register, this embodiment further includes:
server parameters are displayed.
Specifically, in this embodiment, after the server parameter is read from the preset memory according to the acquisition request, and the server parameter is sent to the PNOR, so that the PNOR writes the server parameter into the corresponding target register, the server parameter that is currently modified is displayed by using the preset display device. In this embodiment, the specific form of the display server parameter is not limited, and in this embodiment, the specific type of the display device is not limited, and may be, for example, a liquid crystal display or a touch screen.
Therefore, the server parameters are further displayed, so that operation and maintenance personnel can conveniently and intuitively check the condition of the currently modified server parameters, and the use experience of a user is further improved.
On the basis of the above embodiment, the technical solution is further described and optimized in this embodiment, and specifically, after the server parameter is read from the preset memory according to the acquisition request, and the server parameter is sent to the PNOR, so that the PNOR writes the server parameter into the corresponding target register, this embodiment further includes:
the updated server parameters and the operation time for updating the server parameters are recorded.
Specifically, in this embodiment, when the modification of the server parameter of the target server is completed, the time for writing the server parameter into the corresponding target register, that is, the operation time for updating the server parameter, is obtained, and then the updated server parameter and the operation time for updating the server parameter are recorded. In the actual operation, the specific recording mode may be a text recording mode, an excel recording mode or a database recording mode, which is not limited in this embodiment, and is selected according to the actual requirement.
In this embodiment, by further recording the updated server parameter and the operation time for updating the server parameter, it is convenient for the operation and maintenance personnel to check the modification condition of the server parameter of the target server, thereby further improving the use experience of the user.
