Method, system, device and storage medium for reading log during operation of solid state disk

Abstract

The present application discloses a method, system, device and computer-readable storage medium for reading a runtime log of a solid-state hard disk, comprising: assigning the size of the runtime log to a data register according to a query instruction sent by a reading device through a PCIe channel; According to the read command sent by the read device through the PCIe channel, the sub-runtime log in the runtime log corresponding to the read command is assigned to the data register for the read device to read through the PCIe channel; this application reads the device Establish a connection with the SSD through the PCIe channel, read the device to send the corresponding message, and assign values ​​to the pre-allocated registers in the SSD, so that the SSD can obtain instructions and assign the runtime log to the data register accordingly. The reading device obtains the runtime log through the data register, which reduces the dependence on the host, can communicate with the host through the in-band PCIe channel, and can directly communicate with the substrate through the out-band PCIe channel, which improves reliability.

Description

technical field [0001] The present invention relates to the technical field of solid-state hard disks, and in particular, to a method, system, device and computer-readable storage medium for reading a solid-state hard disk runtime log. Background technique [0002] The Running Time Log (RTLOG) records the running footprint of the SSD in the past period of time. It is a commonly used debugging method for SSD development engineers and on-site support engineers. However, in actual use, it is found that the existing There are many deficiencies in the operation log of the SSD. [0003] The existing runtime logs can only be obtained by relying on the NVMe channel (NVMe, Non-Volatile Memory express). The host sends the command to obtain the runtime log, and the SSD returns the runtime log, but the NVMe channel depends on the host's NVMe driver and PCIe channel. The normal operation of (PCIe, peripheral component interconnect express, peripheral device interconnect bus) is too simp...

Problems solved by technology

[0003] Existing runtime logs can only be obtained by relying on the NVMe channel (NVMe, Non-Volatile Memory express). The host sends a command to obtain the runtime log, and the solid-state drive returns the runtime log, but the NVMe channel depends on the NVMe driver and PCIe channel of the host. (PCIe, peripheral component interconnect express, peripheral device interconnect bus) normal operation, the acquisition method is too simple, once NVMe fails, even if the host and solid-state disk are normal, the runtime log will not be obtained
