Problems solved by technology

When the power is turned on, if the solid-state hard disk fails, although the firmware can be loaded normally, the power-on process cannot be performed normally due to the failure, so that it cannot be recognized by the upper layer, and the data cannot be restored.

Abstract

The invention discloses a method for recovering an abnormal state of a hard disk, which comprises the following steps of loading first firmware stored in a first storage position of the hard disk in response to a received power-on instruction; executing a subsequent power-on process by using the loaded first firmware; loading second firmware stored in a second storage position of the hard disk in response to an exception occurring when the subsequent power-on process is executed; establishing connection with an upper-layer system by using the second firmware so as to enable the upper-layer system to identify the hard disk; and receiving a command issued by the upper system to recover the hard disk. The invention further discloses a system, computer equipment and a readable storage medium. According to the scheme provided by the invention, when the power-on process cannot be normally executed after the normal firmware is loaded, the special firmware is loaded, and the minimum system startup is realized by utilizing the special firmware to establish the connection with the upper system, so that the normal identification of the hard disk is ensured, the influence of the software fault of the hard disk on the user is greatly retrieved, and the continuity of the user service is ensured.

Description

technical field [0001] The invention relates to the field of storage, in particular to a recovery method, system, equipment and storage medium for an abnormal state of a hard disk. Background technique [0002] With the development of technologies such as the Internet, cloud computing, and the Internet of Things, solid-state drives are widely used as a new generation of storage. [0003] As the bottom of the data center, SSD carries the key task of storing data. When the power is turned on, if the solid-state hard disk fails, although the firmware can be loaded normally, the power-on process cannot be performed normally due to the failure, so that it cannot be recognized by the upper layer, and the data cannot be recovered. Contents of the invention [0004] In view of this, in order to overcome at least one aspect of the above-mentioned problems, an embodiment of the present invention proposes a recovery method for an abnormal state of a hard disk, including the followin...
