Problems solved by technology

[0011] In this way, the complexity of the software in the storage controller is increased, and the software in each storage controller is not universal
[0012] Moreover, since it is difficult to distinguish the disks with multiple positioning lights on when positioning multiple disks in different disk cabinets at the same time, it can only be done one by one. One disk realizes positioning, making the efficiency of disk positioning low

Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0035] figure 2 It is a schematic flowchart of a method for locating a disk in a storage system in an embodiment of the present invention. Such as figure 2 As shown, the disk positioning method in this embodiment includes:

[0036] In step 200, an identifier uniquely identifying the disk cabinet is respectively set in each disk cabinet.

[0037] Wherein, the sequence of the identifiers of the disk cabinets may or may not be consistent with the sequence of the disk cabinets in the disk cabinet link, which mainly depends on the actual networking situation.

[0038] In practical applications, since each disk cabinet can usually be connected to a host, and each disk cabinet usually includes a non-volatile memory, therefore, in this step, through the ho...

Abstract

The invention discloses a disk position fixing method in a storage system. The invention separately in each disk cabinet pre-arranges a mark which only marks the disk cabinet, and after gaining the mark of each disk cabinet, the invention need not a software in a storage controller to distribute the mark for each disk cabinet, but can directly realize the disk position fixing according to the gained mark and disk information of each disk cabinet. Moreover, in a state of a ring mode adopting double storage controller, the mark of each disk cabinet gained by the two storage controller are both the same and need not the software in the storage controller to turn over the order of arrangement of the mark of each disk cabinet. The invention also can separately arrange a display unit for each disk cabinet, and differentiate a plurality of disks of which positioning lights are lighted up via the display unit displaying the mark of the disk cabinet which is near from the display unit. The invention also discloses the storage system for realizing the disk position fixing.

Description

technical field [0001] The invention relates to positioning control technology, in particular to a disk positioning method in a storage system and a storage system for realizing disk positioning. Background technique [0002] A storage system usually includes a storage controller and several serially connected disk enclosures, and each disk enclosure includes several disks. With the increasing complexity of the storage system and the more complex networking methods, the number of disk cabinets and disks is also increasing. In order to maintain the disk cabinets, it is necessary to Pinpoint any disk that needs to be tested, replaced or repaired. [0003] figure 1 It is a schematic flowchart of a disk positioning method in an existing storage system. Such as figure 1 As shown, the method includes: [0004] Step 101, when the system is initialized, the storage controller scans all disk cabinets and receives disk information fed back by each disk cabinet. [0005] Step 102...
