Description

Technical Field

[0001] The present invention relates to the field of servers, and in particular to a fault handling device and a server. Background Art

[0002] With the rapid development of information technology, servers play a vital role in various application scenarios. In many cases, servers are required to run 24 hours a day, or to be repaired as soon as possible when a failure occurs to ensure that the business is not affected. Therefore, debugging technology is particularly important.

[0003] When a server fails, there are two possible scenarios: 1. The server is still running. You can obtain the fault log through the monitoring and management system to analyze and locate the problem.

[0004] 2. The server is down (the machine is turned off and the function fails), and the monitoring and management system cannot access it. It is necessary to restart the machine or obtain the fault log through offline diagnosis.

[0005] If the server crashes, and the cause of the failure is uncertain, offline diagnosis is required to analyze the problem in order to ensure the fault site environment or if a partial failure causes the server to be unable to power on normally. However, the current offline diagnosis methods for servers are limited. A common method is to turn on the power supply of the button battery by pressing a button, light up the fault indicator light, and determine the faulty module. However, this solution is mostly used for offline diagnosis of memory module failures. This method obtains less information and cannot cover all modules.
