Solid state disk runtime log reading method, system and device and storage medium

Abstract

The invention discloses a solid state disk runtime log reading method, system and device and a computer readable storage medium, and the method comprises the steps: assigning the size of a runtime logto a data register according to a query instruction sent by reading equipment through a PCIe channel; assigning a sub-runtime log in the runtime log corresponding to a reading instruction to a data register according to the reading instruction sent by the reading device through the PCIe channel, so as to enable the reading device to read the sub-runtime log through the PCIe channel. According tothe invention, the reading device establishes connection with the solid state disk through the PCIe channel; the reading device sends a corresponding message, assigns values to pre-distributed registers in the solid state disk, so that the solid state disk acquires instructions, and the runtime log is correspondingly assigned to the data register, so that reading equipment acquires the runtime logthrough the data register, the dependence on a host is weakened, the reading equipment can communicate with the host through the in-band PCIe channel and can directly communicate with a substrate through the out-band PCIe channel, and the reliability is improved.

Description

technical field [0001] The present invention relates to the technical field of solid-state hard disks, in particular to a method, system, device and computer-readable storage medium for reading logs during operation of solid-state hard disks. Background technique [0002] The running time log (RTLOG, Running Time Log) records the running footprint of the solid-state hard drive in the past period of time. It is a common and important debugging method for solid-state hard drive 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 solid-state disk. [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 compone...

[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
