Problems solved by technology

However, the BMC will also fail. If the BMC fails and hangs, the black box log in the BMC cannot be captured in real time to confirm the fault phenomenon; and after the BMC hangs, the server needs to be restarted to recover. Data will be lost after power failure, so fault information will not be retained
In addition, restarting after a power failure is equivalent to setting the server once, which will have a relatively large impact on the capture of fault information at that time and subsequent fault recurrence, which in turn will have a great impact on fault analysis and location, and is not conducive to Timely resolution of faults and assessment of risks

example 1

[0089] Example 1. A method for recording fault information, implementing logic such as figure 2 shown, including:

[0090] The BMC records the fault information that occurs during the operation of the server and stores it in the black box log; the BMC sends the black box log to the CPLD in the server through the I2C bus, and the CPLD will receive the black box log through the I2C bus and record it to itself Flash. When the server fails and the BMC hangs, the black box log can be read from the CPLD after connecting to the JTAG through an external tool, and used for fault analysis and problem location.

[0091] In this example, the black box logs of the BMC can be obtained through the CPLD. When the server fails and the BMC hangs up, the availability of the black box logs and the storability of the black box logs can be ensured. Destroyed so as to facilitate on-site failure analysis.

[0092] This example can be implemented mainly through soft-layer code, which saves costs a...

Abstract

The invention discloses a fault information recording method and system. The fault information recording method comprises the steps that a BMC (baseboard management controller) writes in a black box log after obtaining the fault information of a server where the BMC is located; when the BMC meets the triggering condition, the black box log is sent to a complex programmable logic device (CPLD) in aserver where the BMC is located; and the CPLD writes the received black box log into a flash memory of the CPLD. According to the fault information recording method, the fault information can be obtained and the fault site can be reserved under the condition that the server fails and the BMC is suspended.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and system for recording fault information. Background technique [0002] With the development of cloud computing applications, informatization has gradually covered all fields of society. People communicate more and more through the network in their daily work and life, and the amount of network data is also increasing; at the same time, the application of cloud space is also gradually increasing. For the data center computer room that provides cloud computing and cloud space, a high-density computer room is proposed. , high stability requirements, and high requirements for the timeliness of server problem processing. Timely positioning and analysis can ensure the stable operation of cloud computing and cloud space. [0003] Among them, the server boards are highly integrated and high-density; and in the computer room, the servers are also high-density. If the failure of the s...
