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 in a data storage system, comprising:
setting which types of movement are valid in the data storage system;
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, wherein the hard disk information includes the hard disk location and a type of the hard disk;
determining a movement type of the hard disk based on the recognized hard disk information, wherein the recognized hard disk information includes whether the hard disk is one of a system disk and a user disk, used to determine the movement type of the hard disk;
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 whether the hard disk is one of the system disk and the 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, comprising:
a data storage system including two or more hard disks; and
computer-executable program logic encoded in memory of one or more computers enabled to recognize movement of a hard disk, of the two or more hard disks, in the data storage system, wherein the computer-executable program logic is configured for the execution of:
defining which types of movement are valid in the data storage system;
recognizing hard disk information recorded in the hard disk in response to the hard disk being moved to a slot in a hard disk array, wherein the hard disk information includes the hard disk location and a type of the hard disk;
determining a movement type of the hard disk based on the recognized hard disk information, wherein the recognized hard disk information includes whether the hard disk is one of a system disk and a user disk, used to determine the movement type of the hard disk;
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.

8. The system of claim 7 , 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.

9. The system of 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 of claim 9 , 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.

11. The system of claim 9 , wherein the hard disk type information comprise whether the hard disk is one of the system disk and the user disk.

12. The system of claim 11 , wherein the computer-executable program logic is further configured for the execution of: 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.
