Problems solved by technology
[0004] One is to rely on the ipmitool tool to implement BMC out-of-band management. This method has relatively large limitations. It needs to test the server and test nvmessd to support the BMC out-of-band management hot-swap function. However, the current mainstream commonly used servers are large Part of the function that does not support BMC hot-swappable hard disk
Moreover, this method of hot plugging cannot achieve precise control of plugging time and speed, nor can it achieve non-notified hot plugging tests
[0005] The other is realized by setting the POWER state of the corresponding PCIe card slot, which can be understood as unloading and loading nvmessd. This method cannot fully simulate the actual hot-plug test scenario of nvmessd, and can only support notification-type hot-plug , unable to support unannounced hot swap

The invention relates to the technical field of data storage, and provides an NVMe SSD hot plug test method, device and equipment and a storage medium, the method comprises the following steps: obtaining equipment information of a to-be-tested NVMe SSD, and connecting the to-be-tested NVMe SSD to a test host through a storage system component hot plug device; a control instruction is sent to a storage system component hot plug device, the control instruction carries preset test parameters and device information, so that the storage system component hot plug device configures on-off delay information of a target signal pin according to the test parameters, and the target signal pin is a signal pin for establishing a connection relation between the to-be-tested NVMe SSD and a test host; and controlling the hot plug device of the storage system component to perform on-off control on the target signal pin according to the on-off delay information so as to simulate a hot plug scene of the to-be-tested NVMe SSD. According to the invention, the purpose of accurately and quickly testing the hot plug function of the NVMe SSD can be achieved.
Description
technical field [0001] The present invention relates to the technical field of storage device failure testing, in particular to a NVMe SSD hot swap testing method, device, equipment and storage medium. Background technique [0002] In recent years, with the rapid development of industries such as cloud computing, big data, and the Internet of Things, the demand for data storage is increasing. Since nvmessd (non-volatile memory express solid state disk, non-volatile memory host controller interface specification solid state disk) has the characteristics of large capacity, fast read and write speed, low io delay, etc., whether it is in the consumer or enterprise market , the market size of nvmessd is greatly increasing. In different application scenarios, nvmessd has been applied on a large scale, and the requirements for the use of nvmessd are becoming more and more diversified. Therefore, the reliability requirements for nvmessd are also getting higher and higher. . If the...
