A colleague discovered that the number of message logs on a certain machine suddenly increased sharply. After a brief check, there were memory-related errors, so he forwarded them to me for review.

Message log

Enter the server to view the message log. First, see what the alarm mentioned by the colleague is, as shown below:
Use log analysis to easily diagnose hardware failures
Really, channel 3, the memory in the first slot failed. However, I only know A1/B1/A2/B2, so I continue.

Ipmitool tool

No matter what, after checking it with the Ipmitool tool, there is indeed a memory alarm, as shown below

Although there is an alarm, it is impossible to locate the specific memory that is broken

IDRAC-web

No matter what, we still have the web page of DELL's own IDRAC to check the hardware status. Log in and take a look. First, look at the log. Here it is, B6 memory slot failure

Look at the hardware status again, there is an alarm in B6 memory

In this regard, I found the information I wanted and located the B6 memory failure, which needs to be replaced. As for how to replace it and what matters need to be paid attention to, I will talk about it later.

Summarize

Hardware security is the lowest level of security for the server. You must monitor the hardware and deal with hardware failures in a timely manner. Otherwise, you will understand. Introducing several common logs involving hardware failure analysis:

  1. messages log
  2. dmesg log
  3. ipmitool sel list view hardware log
  4. Logs on the remote management page (DELL's IDRAC, HP's ILO, IBM's IMM, etc.)
  5. smart log

The above is the detailed content of Use log analysis to easily diagnose hardware failures. For more information, please follow other related articles on the PHP Chinese website!

What are the differences in how Linux and Windows handle device drivers?What are the differences in how Linux and Windows handle device drivers?Apr 25, 2025 am 12:13 AM

The differences between Linux and Windows in handling device drivers are mainly reflected in the flexibility of driver management and the development environment. 1. Linux adopts a modular design, and the driver can be loaded and uninstalled dynamically. Developers need to have an in-depth understanding of the kernel mechanism. 2. Windows relies on the Microsoft ecosystem, and the driver needs to be developed through WDK and signed and certified. The development is relatively complex but ensures the stability and security of the system.

Learning Linux is not difficult. 1.Linux is an open source operating system based on Unix and is widely used in servers, embedded systems and personal computers. 2. Understanding file system and permission management is the key. The file system is hierarchical, and permissions include reading, writing and execution. 3. Package management systems such as apt and dnf make software management convenient. 4. Process management is implemented through ps and top commands. 5. Start learning from basic commands such as mkdir, cd, touch and nano, and then try advanced usage such as shell scripts and text processing. 6. Common errors such as permission problems can be solved through sudo and chmod. 7. Performance optimization suggestions include using htop to monitor resources, cleaning unnecessary files, and using sy
