Problems solved by technology

However, by adding hardware to provide the above functions, the production cost will inevitably increase accordingly
Correspondingly, the selling price will also rise accordingly, making the competitiveness of the product vulnerable to being reduced by the price factor

[0019] figure 1 It is a flow chart of the method for automatically rebuilding a hard disk according to the first embodiment of the present invention. Please refer to figure 1 First, step S110 is performed at the initial stage of system establishment to initialize the first hard disks, and record and save the data configuration information of the first hard disks. Because these first hard disks can belong to different disk array groups according to requirements during system planning. Wherein, these different disk array groups can simultaneously provide services of different disk array levels on the host.

[0020] For example, some groups in the host are responsible for providing level 0 services to speed up the reading speed, while another part of the groups provide level 1 or level 5 fault tolerance and backup services. Therefore, after initializing the first hard disks, it is necessary to save the data configuration information corresponding to the disk array level and th...

[0026] figure 2 It is a flowchart of a method for automatically rebuilding a hard disk according to the second embodiment of the present invention. This embodiment is similar to the first embodiment, the differences will be described below, and similar steps will not be described in detail. Please refer to figure 2 , initializing the first hard disks at the initial stage of system establishment, and recording and saving the data configuration information of the first hard disks (step S210).

[0027]Next, proceed to step S220, and detect whether a hard disk is inserted into or pulled out of the hard disk slot through the pins arranged on each hard disk slot. Wherein, step S220 includes two sub-steps of S222 and S224: step S222, when a hard disk is inserted into or pulled out of the hard disk slot, an interrupt signal is generated through a pin; step S224: when the interrupt signal is received, scan all hard disk slots, to find out which hard disk slot has a hard disk inser...

Abstract

The invention provides an automatic reconstruction method of hard disks, which is applied for the host adopting the disk array, wherein the disk array includes a plurality of first hard disks. Each first hard disk is connected to the hard disk slot of the host through a small computer system interface. The method includes following steps: firstly initializing these first hard disks, and recording the data configuration information of these first hard disks; next detecting whether a hard disk is inserted in or drawn out from the hard disk slot through the pins configured on each hard disk slot; when detecting that a second hard disk is inserted, researching the data configuration information according to the inserting / drawing data, wherein the data configuration information corresponds to the hard disk slot with the inserted second hard disk; and then reconstructing the second hard disk according the backup data stored in other first hard disks according to the data configuration information.

Description

technical field [0001] The present invention relates to a method for rebuilding a hard disk, and in particular relates to a method for automatically rebuilding a hard disk. Background technique [0002] Nowadays, network technology is becoming more and more mature. Whether it is in enterprises or schools, the proportion of information transmission and exchange relying on the network is getting higher and higher, and the reliability of the server as an information exchange platform is also becoming more and more important. Therefore, when there is a problem with the hardware of the server, it is often necessary to replace part of the hardware without stopping the server, so as to ensure that the communication of information is not interrupted. In addition, the server also needs to have the function of data fault tolerance, so that the data can be restored in time when the data is damaged. [0003] In order to replace part of the hardware without stopping the server, the serv...
