Server power failure detection method, system and device and medium

Abstract

The invention discloses a server power failure detection method, system and device and a storage medium, and the method comprises the steps: responding to the power-on completion of hardware, and controlling a PCH to read a BIOS code from a BIOS flash memory storage particle through a first interface and operate; detecting whether a bit of a register of the PCH is set or not; in response to the fact that the bit of the register of the PCH is set, controlling the PCH to send power failure completion information to the BMC through the second interface; and in response to the fact that the BMC receives the power-down completion information, recording the power-down completion information into the BMC flash memory storage particles, and returning to carry out hardware power-on again until thetest is completed. According to the method, whether the bit of the register of the PCH is set or not is detected by utilizing the BIOS, and the power failure completion information is sent to the BMC,so that the method has very high universality, an oscilloscope is not needed, and the detection cost is reduced.

Description

technical field [0001] The present invention relates to the field of servers, and more specifically refers to a method, system, computer equipment and readable medium for server power-off detection. Background technique [0002] The general server has AC Cycle test in the design stage. The test process of this test is: the server is powered on AC (alternating current) → the system automatically starts → enters the OS (system) → executes the shutdown script under the OS → the server enters the S5 state (S5 state: AC Power supply until the power-on is completed)→AC power-off→interval for a certain period of time→server AC power-on, and then continue to the next round of power-on and power-off tests. [0003] This test is mainly to simulate whether the server is in the computer room of the data center. If the AC power supply of the computer room is unstable, whether the server can be automatically turned on after intermittent power failure and power supply. In the AC test, the...

Problems solved by technology

However, in the AC measurement environment, the machine is repeatedly powered on and off, and it is necessary to use the oscilloscope probe to touch the test point of the power supply. This test method takes time to set up the test environment and has the risk of short circuiting the circuit board; AC In the measurement environment, the machine is repeatedly powered on and off, and the chassis has a large electromagnetic field change, which will affect the accuracy of the oscilloscope voltage measurement.
