Problems solved by technology

[0004] Since the way of connecting the SATA port to the hard disk cannot use hardware RAID, the cloud storage data storage node does not use the way of connecting the SATA port to the hard disk, but uses the way of connecting the RAID card to the hard disk. This method is recognized in the Linux system as host0 , so the traditional method cannot be used to identify the hard disk bay

Embodiment Construction

[0018] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0019] see figure 1 , is a system architecture diagram of a hard disk bay identification system for a data storage node in an embodiment of the present invention. The data storage node hard disk slot identification system 100 runs on a host computer running on a Linux device, and the Linux device includes a host computer and a disk slot connected to the host computer for inserting a hard disk. The data storage node hard disk position identification system includes a building module 10 and an identification module 20 .

[0020] The establishment module 10 is used to use the udev device manager to establish a rule file according to the rules of udev. The rule file is used to identify the disk position of the kernel device by running the ide...

Abstract

The invention discloses a data storage node hard disk position identification method applied to a host of Linux equipment. The Linux equipment comprises the host and a disk position connected with the host and used for allowing a hard disk to be inserted. The method includes the following steps that S1, a udev device manager is used for building a rule file according to udev rules, and the rule file is used for disk position identification by operating an identification shell script; S2, when a Linux inner core detects inner core devices, the udev device manager is used for operating the identification shell script, carries out disk position identification on the inner core device meeting requirements of the rules through analysis of a generated file driven by an RAID card, and then outputs a disk position identification result corresponding to the inner core device. The invention further discloses a data storage node hard disk position identification system.

Description

technical field [0001] The invention relates to a method and system for identifying a hard disk position of a data storage node. Background technique [0002] The disk slot is the hard disk slot of a single device without the connected expansion cabinet and array. The traditional hard disk identification method is through multiple SATA ports on the motherboard, each SATA port corresponds to host0, host1,...,hostn in the Linux system, and then through host0,host1,...,hostn to identify Hard drive tray. SATA (Serial Advanced Technology Attachment, Serial Advanced Technology Attachment) is a serial hardware drive interface based on industry standards. In actual use, SATA's HBA (Host Bus Adapter, host bus adapter) is like a switch on the network Similarly, it is possible to communicate with each individual hard disk in the form of a channel, that is, each SATA hard disk has an exclusive transmission channel. [0003] RAID (Redundant Array of Independent Disks, Redundant Array ...
