AI Technical Summary

Problems solved by technology

Under normal circumstances, because the FW needs to do control self-test, hardware self-test, IO recovery and other processes when starting the FW, the FW reset time ranges from 30s / 40s to 1 minute, which is very time-consuming
Moreover, in the process of FW reset, it may also be accompanied by serious problems such as failure to start (FW hang) due to self-test failure, that is, staying in a certain state and no longer running, and repeated FW resets.
When the hard disk fails to respond, the hard disk side and the array side cannot perform IO transmission, and the IO sent from the array side to the hard disk side cannot respond (that is, the upper layer IO times out), and finally the business on the array is seriously affected.

Embodiment Construction

[0034] The technical solution in this application will be described below with reference to the accompanying drawings.

[0035] figure 1 A schematic block diagram of a hard disk 100 provided by the embodiment of the present application is shown. Such as figure 1 As shown, the hard disk 100 includes a first firmware FW101 and a second firmware FW102, wherein the first FW101 and the second FW102 share a shared data area.

[0036] The first FW101 is used to realize the complete function of the hard disk, which can respond to IO access of external devices and perform data processing during normal operation. The following will describe the technical solution of the present application by taking the external device as the first device as an example. In addition, the first FW 101 can also be used for performing background tasks (such as scanning media for bad sectors), status light control, configuration control and other operations. Here, the first FW 101 may also be called the ...

Abstract

A hard disk self-healing device, method, and hard disk are provided. The HDD self-healing device, includes a first firmware FW and a second firmware FW, As opposed to having only a single FW in that prior art, by provide a first FW and a second FW, When the first FW fails to restart, the second FW can quickly take over the control of the external IO and the data processing, thereby avoiding the first FW from being unable to respond in the reset period, thereby helping to reduce the impact on the service or avoid the impact on the service.

Description

technical field [0001] The present application relates to the field of computer hardware equipment, and more specifically, to a hard disk self-healing device, method and hard disk. Background technique [0002] The firmware (firmware, FW) inside the hard disk is used as the driver program inside the hard disk, and is used for input and output (input and output, IO) access control, data interaction control, and hard disk hardware control on the hard disk. When the FW runs abnormally, for example, the program software suddenly shuts down and enters an abnormal state (OOPS), the most direct processing strategy of the existing hard disk FW is to restart the FW program (FW reset), that is, initialize the operation of the FW program. In general, because the FW needs to perform control self-check, hardware self-check, IO recovery and other processes when starting the FW, the FW reset time ranges from 30s / 40s to 1 minute, which is very time-consuming. Moreover, in the process of FW...
