Problems solved by technology

[0002] In the field of storage, NVMe SSD (NVMe solid-state drive) is directly connected to the general-purpose PCIe Bus (PCIe bus), and the hot plug of NVMe SSD is completely dependent on the PCIe processing mechanism of the Host, but the traditional PCIe processing mechanism is not suitable for hot plugging. The support for ease of use is not good, especially the violent hot plug (PCIe surprise hot plug), which can easily lead to poor serviceability of the NVMeSSD corresponding storage system

Abstract

The invention discloses a hot plug processing method, device and equipment, and the method comprises the steps: determining equipment with a hot plug-in event as plug-in equipment when a PCIe hot plug-in event occurs; if the plug-in equipment is a PCIe switch, scanning a downlink port of the plug-in equipment, initializing the hard disk mounted at the downlink port of the plug-in equipment when the hard disk is mounted at the downlink port of the plug-in equipment, and if the plug-in equipment is the hard disk, initializing the plug-in equipment; when a PCIe hot pull-out event occurs, determining the equipment in which the hot pull-out event occurs as a pull-out device; and if the pull-out equipment is a PCIe switch, scanning a downlink port of the pull-out device, when the hard disk is mounted at the downlink port of the pull-out device, cancelling the hard disk mounted on the downlink port of the pull-out device and recovering corresponding resources, and if the pull-out device is the hard disk, cancelling the pull-out device and recovering the corresponding resources. Good hot plug support usability and good serviceability of a corresponding storage system can be realized.

Description

technical field [0001] The present invention relates to the field of storage technology, and more specifically, to a hot swap processing method, device and equipment. Background technique [0002] In the field of storage, NVMe SSD (NVMe solid-state drive) is directly connected to the general-purpose PCIe Bus (PCIe bus), and the hot plug of NVMe SSD is completely dependent on the PCIe processing mechanism of the Host, but the traditional PCIe processing mechanism is not suitable for hot plugging. The support for ease of use is not good, especially the violent hot plug (PCIe surprise hot plug), which can easily lead to poor serviceability of the NVMeSSD corresponding storage system. Contents of the invention [0003] The purpose of the present invention is to provide a hot-swap processing method, device and equipment, which can realize better usability of hot-swap support, and further realize better serviceability of corresponding storage systems. [0004] In order to achie...
