BBU fault diagnosis method and device, electronic equipment and storage medium

Abstract

The invention discloses a BBU fault diagnosis method, and the method comprises the steps: firstly judging whether a power supply is normal or not in a process of switching from a main power supply toa target BBU through power supply switching data, and accurately positioning a fault in a switching logic if the power supply is not normal; and if the target BBU is normal, subsequently determining the working state of the target BBU through the hardware signal of the target BBU, determining whether the target BBU is abnormal or not in the operation process based on the working state, and if thetarget BBU is abnormal, further determining a specific abnormal source causing the abnormality through fault simulation so as to perform targeted repair to recover the target BBU to be normal. Throughdeep analysis of the actual operation process of the BBU, all sources possibly causing the BBU fault are judged layer by layer, so that the fault determination accuracy is gradually improved, and theafter-sales service cost is also effectively reduced based on the full-automatic operation process of the machine. The invention further discloses a BBU fault diagnosis device, electronic equipment and a readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of storage system operation assurance, and in particular to a BBU fault diagnosis method, device, electronic equipment and readable storage medium. Background technique [0002] In the era of big data, higher requirements are put forward for the reliability of storage devices, especially for backup battery unit (BBU) and primary power supply related problems analysis and positioning efficiency and accuracy. [0003] Once the storage system has a BBU / PSU (industrial power supply) related problem, it needs to be analyzed, tested and verified. Traditional technology often requires staff to visit the customer's equipment site for manual debugging and analysis. The staff needs to check the retrieved BBU work logs one by one, which is not only inefficient, but also prone to omissions due to human instability. In particular, some on-site low-probability problems that are difficult to reproduce are even m...

AI Technical Summary

Problems solved by technology

Traditional technology often requires staff to go to the customer's equipment site for manual debugging and analysis. The staff needs to check the retrieved BBU work logs one by one, which is not only inefficient, but also prone to omissions due to human instability.

Especially some on-site low-probability problems that are difficult to reproduce are even more difficult to find and trace

These problems prolong the storage product design and development verification cycle, increase the cost of after-sales service, and reduce the stability and reliability of storage products.
