Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a BIOS serial port log testing system and method based on SOL. Background Art

[0002] At present, when BIOS starts to initialize the hardware and boot the OS, the BIOS operation log will be printed through the serial port. In this way, during the server development and debugging process, technicians can output the serial port log through the COM port, that is, connect to the serial port line to view the output of the BIOS log in real time, and develop and debug the BIOS according to the BIOS log.

[0003] However, the traditional BIOS serial port error checking test has the following disadvantages:

[0004] (1) It mainly relies on the server under test to connect to the client through a serial port line. The client uses Putty and other serial port software to capture the serial port to check whether there is Error or Fail on the serial port, and check whether the machine stops outputting at a specific position due to a crash.

[0005] (2) This method has the obvious disadvantage that it must rely on the physical connection of the serial port line. One machine under test requires one client machine to capture, which is not conducive to long-term testing of multiple servers at the same time, and the operation is complicated;

[0006] (3) The client can log in to the BMC client through SSH and manually start SOL through complex commands to print the serial port log, but the serial port information cannot be saved locally, or the serial port information saved locally cannot be printed on the screen, resulting in the inability to perform intuitive debugging and BIOS serial port log testing. Summary of the invention

[0007] The purpose of the present invention is to provide a BIOS serial port log testing system and method based on SOL, so as to solve the problem proposed in the above background technology that the tested server is mainly relied on to connect to the client through a serial port line, and the client grabs the serial port through Putty serial port software to check whether there are Error and Fail words on the serial port, and whether the machine stops outputting at a specific position due to a dead serial port; this method has obvious disadvantages that it must rely on the physical connection of the serial port line, and one tested machine requires one client machine to grab, which is not conducive to long-term testing of multiple servers at the same time, and the operation is complicated; the client logs in to the BMC client through ssh and manually opens SOL to print the serial port log through complex instructions, but the serial port information cannot be saved locally, or the serial port information saved locally cannot be printed on the screen, resulting in the problem that intuitive debugging and BIOS serial port log testing cannot be performed.

The serial port switching module switches the serial port to SOL mode and establishes a SOL session through a standard IPMI command. The data reading module sets a time interval according to the performance of the mainboard and reads data from the network card interface.
