Embodiment Construction

[0035] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments. The following examples are only used to illustrate and explain the present invention, but not to limit the technical solution of the present invention.

[0036] Such as figure 1 As shown, it is the process flow of the embodiment of the disk positioning method for realizing the high-end disk array of the present invention, including the following steps:

[0037] 110: Obtain the address of the disk through the agreement between the disk and the operating system according to the name of the disk;

[0038] In high-end disk arrays, it is common to follow the protocol standard between the disk and the operating system is the Small Computer System Interface (SCSI, Small Computer System Interface) protocol.

[0039] For example, when a disk in a high-end disk array is found to be abnormal, the 0x83 protocol page information ...

Abstract

The invention discloses a disk positioning method and a disk positioning device for realizing a high-end disk array. The method comprises the following steps of: acquiring an address of a disk by using a protocol between the disk and an operating system according to the name of the disk; and querying the address of the disk in an expander by using the protocol according to the acquired address of the disk so as to determine a physical position of the disk. In the invention, information such as a disk position is immediately acquired by using a protocol standard between the disk and the operating system, and the positioned disk is indicated by modifying disk state information, so the technical problem of unreliable application of the high-end disk array is solved.

Description

technical field [0001] The invention relates to a mass storage system, in particular to a disk positioning method and device for realizing a high-end disk array in the mass storage system. Background technique [0002] With the continuous development of applications such as digital libraries, e-commerce, and multimedia transmission, especially the application of massive data services such as financial telecommunications, exploration and surveying, bioengineering, meteorology, and energy, the data ranges from GB (=1024MB), TB (=1024GB ) to the PB (=1024TB) magnitude and the rapid growth. Storage products are no longer auxiliary equipment attached to servers, but have become the most important expense in the Internet. Mass storage has become the third wave following the computer wave and the Internet wave, and disk arrays and network storage have become pioneers. [0003] For high-end disk arrays used in mass storage systems, from the perspective of disk types and available ...
