Abstract

A system and method of recognizing a hard disk movement, the system and method including recognizing hard disk information recorded in a hard disk in response to the hard disk being moved to a slot in a hard disk array, determining the movement type of the hard disk based on the recognized hard disk information, judging validity of the hard disk movement based on the movement type, and updating the hard disk information of the hard disk in response to the hard disk movement being judged as valid, wherein the hard disk information comprises position information of the hard disk in the hard disk array.

First claim

What is claimed is:

1 . A method of recognizing a hard disk movement, comprising:
recognizing hard disk information recorded in a hard disk in response to the hard disk being moved to a slot in a hard disk array; determining the movement type of the hard disk based on the recognized hard disk information; judging validity of the hard disk movement based on the movement type; and updating the hard disk information of the hard disk in response to the hard disk movement being judged as valid; wherein the hard disk information comprises position information of the hard disk in the hard disk array.

2 . The method of recognizing the hard disk movement according to claim 1 , wherein determining the movement type of the hard disk comprises:
comparing a position of the hard disk in the hard disk array and the position information in the hard disk.

3 . The method of recognizing the hard disk movement according to claim 1 , wherein the hard disk information further comprises at least one of the following items:
hard disk type information; initialization information; and array serial number information.

4 . The method of recognizing the hard disk movement according to claim 3 , wherein determining the movement type of the hard disk comprises:
comparing an array serial number of the hard disk in the hard disk array and the array serial number information in the hard disk.

5 . The method of recognizing the hard disk movement according to claim 3 , wherein the hard disk type information comprise system disk and user disk.

6 . The method of recognizing the hard disk movement according to claim 5 , comprising:
judging whether the hard disk belongs to a redundant array of independent hard disk in response to the hard disk type information being recognized as the user disk.

7 . A system for recognizing a hard disk movement, comprising:
a hard disk information recognizing unit configured to recognize hard disk information recorded in the hard disk in response to the hard disk being moved to a slot in a hard disk array; a movement type determining unit configured to determine the movement type of the hard disk based on the recognized hard disk information; a movement validity judging unit configured to judge validity of the hard disk movement based on the movement type; and a hard disk information updating unit configured to update the hard disk information of the hard disk in response to the hard disk movement being judged as valid; wherein the hard disk information comprises position information of the hard disk in the hard disk array.

8 . The system for recognizing the hard disk movement according to claim 7 , wherein the movement type determining unit comprises:
a position information comparing unit configured to compare the position of the hard disk in the hard disk array and the position information in the hard disk.

9 . The system for recognizing the hard disk movement according to claim 7 , wherein the hard disk information further comprises at least one of the following items:
hard disk type information; initialization information; and array serial number information.

10 . The system for recognizing the hard disk movement according to claim 9 , wherein the movement type determining unit comprises:
an array serial number comparing unit configured to compare an array serial number of the hard disk in the hard disk array and the array serial number information in the hard disk.

11 . The system for recognizing the hard disk movement according to claim 9 , wherein the hard disk type information comprises system disk and user disk.

12 . The system for recognizing the hard disk movement according to claim 11 , comprising:
a redundant array of independent hard disk judging unit configured to judge whether the hard disk belongs to a redundant array of independent hard disk in response to the hard disk type information being recognized as the user disk.
