Problems solved by technology

Because this solution is designed for desktop systems, and all hard disk partitions of the same capacity on the NAS system have the same structure, and the file system is not directly created on the hard disk partition, so the serial number of the file system cannot be obtained, so this solution does not work. Suitable for NAS systems as a method to identify hard drives

Embodiment Construction

[0037] Such as figure 1 As shown, it is a flow chart of the hard disk replacement control management method used in the network storage system of the present invention. First, record the tag data that can identify the hard disk in the hard disk (step 101); correspondingly record the data in the information file in the network storage system. Mark the data (step 102); simultaneously detect the actions of system startup and hard disk replacement (step 103); read the mark data of the hard disk and compare it with the corresponding data in the system file to determine the availability of the hard disk (step 104).

[0038] Wherein the hard disk mark data is recorded in the unused hidden sector of the hard disk, and the hidden sector refers to n unused sectors of the system whose sector number is smaller than the number of magnetic heads behind the master boot sector (MBR) of the hard disk. The number of magnetic heads of the current hard disk is greater than 16, so at least 15 sect...

Abstract

The invention relates to a hard disk changing control manage method used in network storage system. The record of mark data in hard disc is used as the reference of hard disc insert / pull-out management in order to change hard disc expediently. The mark data is recorded into hard disc, and registering the mark data corresponding to the record in information file in the network storage system. Meanwhile, checking the action of system starting and hard disk changing, when the actions are checked, the mark data would be read and compared to the corresponding data in system file to confirm the usability of the hard disc. The invention uses hard disc mark data records as the reference of hard disc management, supports hot / cool plug and keeps the consistent of the access path.

Description

technical field [0001] The invention relates to a hard disk control and management method in a data storage system, in particular to a hard disk replacement control and management method for a network storage system. Background technique [0002] At present, there are three main modes of disk storage on the market: CAS content addressable storage, NAS network attached storage or network attached storage, and SAN storage local area network. The latter two are the main choices in the network environment. [0003] After two rapid developments in computer computing power and network connectivity, people's demand for the network is no longer satisfied with connectivity, but more powerful information management capabilities. As more and more critical information is converted into digital form and stored in manageable media, new demands are placed on the network's ability to store and manage information. It can be said that whether the network has high efficiency depends on its da...
