Method, apparatus, and device for transmitting file based on BMC, and medium
View Patent ↗A method, an apparatus, and a device for transmitting a file based on a BMC, and a medium are provided. The method includes: receiving, by a second BMC, a preset command sent by a first BMC, where the preset command indicates that transmission of a file is to be initiated; parsing the preset command, and stopping an IPMI process running based on a UART interface in response to the preset command; and receiving, by using a communication function of the UART interface, a data file transmitted by the first BMC. With the method, when the data file is transmitted between the BMCs, the data file is not intercepted and verified by the preset command processing function of the IPMI process running based on the UART interface, and the IPMI process is prevented from being blocked and crashing, thereby implementing transmission of data files between BMCs.
1. A method for transmitting a file between Baseboard Management Controllers (BMCs), comprising:
receiving, by a second BMC, a preset command sent by a first BMC, wherein the first BMC communicates with the second BMC through a Universal Asynchronous Receiver/Transmitter (UART) interface, and the preset command indicates that transmission of a file is to be initiated;
parsing the preset command, and stopping an Intelligent Platform Management Interface (IPMI) process in response to the preset command, wherein the IPMI process intercepts and verifies a control command received through the UART interface; and
receiving, by using a communication function of the UART interface, a data file transmitted by the first BMC.
2. The method according to claim 1 , wherein the parsing the preset command, and stopping the IPMI process in response to the preset command comprises:
parsing the preset command, and modifying a value of a preset flag variable from an initial value to a flag value in response to the preset command, and
monitoring the flag variable by using a preset process, and stopping the IPMI process by calling a system function when the value of the flag variable is the flag value.
3. The method according to claim 2 , wherein after the receiving, by using the communication function of the UART interface, the data file transmitted by the first BMC, the method further comprises:
modifying the value of the flag variable to the initial value, and restarting the IPMI process in the second BMC by calling the system function.
4. The method according to claim 2 , wherein after the stopping the IPMI process by calling the system function, the method further comprises:
recording, in a log file, a time instant at which the IPMI process is stopped and parameter information of the second BMC in correspondence with each other.
5. The method according to claim 2 , wherein the initial value is 1, and the flag value is 0.
6. The method according to claim 1 , wherein the data file is a mirror file of a bin type.
7. A device for transmitting a file between Baseboard Management Controllers (BMC), comprising:
a memory, configured to store a computer program; and
a processor, configured to execute the computer program to implement steps of:
receiving, by a second BMC, a preset command sent by a first BMC, wherein the first BMC communicates with the second BMC through a Universal Asynchronous Receiver/Transmitter (DART) interface, and the preset command indicates that transmission of a file is to be initiated,
parsing the preset command, and stop an Intelligent Platform Management Interface (IPMI) process in response to the preset command, wherein the IPMI process intercepts and verifies a control command received through the UART interface, and
receiving, by using a communication function of the UART interface, a data file transmitted by the first BMC.
8. The device according to claim 7 , wherein the parsing the preset command, and stopping the IPMI process in response to the preset command comprises:
parsing the preset command, and modifying a value of a preset flag variable from an initial value to a flag value in response to the preset command, and
monitoring the flag variable by using a preset process, and stopping the IPMI process by calling a system function when the value of the flag variable is the flag value.
9. The device according to claim 8 , wherein after the receiving, by using the communication function of the UART interface, the data file transmitted by the first BMC, the processor is further configured to execute the computer program to implement a step of:
modifying the value of the flag variable to the initial value, and restarting the IPMI process in the second BMC by calling the system function.
10. The device according to claim 8 , wherein after the stopping the IPMI process by calling the system function, the processor is further configured to execute the computer program to implement a step of:
recording, in a log file, a time instant at which the IPMI process is stopped and parameter information of the second BMC in correspondence with each other.
11. The device according to claim 8 , wherein the initial value is 1, and the flag value is 0.
12. The device according to claim 7 , wherein the data file is a mirror file of a bin type.
13. A non-transitory computer readable storage medium, storing a computer program, the computer program being executed by a processor to implement steps of the method for transmitting a file between Baseboard Management Controllers (BMCs) according to claim 1 .
