Problems solved by technology

[0003] When a dual-port hard disk is selected for data storage, under normal circumstances, the dual ports of the hard disk are visible to the dual nodes connected to the dual ports of the storage system. The node of the hard disk is not visible, resulting in only one port available for the hard disk, which in turn affects the related data processing and storage services.
In the existing technology, there is a lack of port monitoring for the hard disk, and it is impossible to detect the port failure of the hard disk in time and quickly repair or replace the hard disk, which affects the integrity of data storage and the normal operation of data processing services.

[0036] see figure 1 , which is a schematic flowchart of a method for repairing a hard disk port provided by an embodiment of the present application.

[0037] It should be noted that the hard disk port repair method provided in the embodiment of the present application can be applied to a storage device including or having a dual-port hard disk.

[0038] It should be noted that the hard disk port repair method provided in the embodiment of the present application can be applied to a storage system having a drive, a chassis management module, or a device module having a similar function.

[0039] In this embodiment, the method may be implemented, for example, through the following steps S101-S103.

[0040] S101: The enclosure management module receives the visible state information of the hard disk port sent by the drive; wherein the visible state information is acquired by the drive after the hard disk establishes a connection with the storage system.

[0041] It should be n...

[0053] In view of the above situation, the present application provides another embodiment of a hard disk port repair method, which can add a re-judgment and re-inspection mechanism to avoid repairing hard disks that are temporarily invisible but not faulty, and ensure that the repaired hard disk can For normal work, mark hard disks that cannot be repaired for easy handling by technicians. Considering that the direct communication between the driver and the chassis management module and other modules will increase the difficulty of storage system design, the communication between the chassis management module and other upper-layer modules and the driver is carried out through the interface layer. The flowchart of another hard disk port repair method provided by the embodiment of this application refers to figure 2 shown.

[0054] S201: The chassis management module receives the visible state information of the hard disk port sent by the drive; wherein the visible state infor...

[0074] see image 3 , image 3 It is a schematic structural diagram of a repairing device for a hard disk port provided by an embodiment of the present application.

[0075] For example, the apparatus 300 may specifically include: a driver 301 and a chassis management module 302 .

[0076] The driver 301 is configured to obtain the visible status information after the dual-port hard disk is connected to the storage system and send the visible status information to the chassis management module 302;

[0077] The chassis management module 302 is configured to judge whether the dual-port hard disk has a problem that one port is not visible according to the obtained visible status information, and repair the hard disk with the problem.

[0078] Optionally, the chassis management module includes: a re-judgment unit, which is used for the chassis management module to judge whether the hard disk port has an invisible problem after a certain period of time after judging that the har...

Abstract

The invention discloses a hard disk port repairing method and device. The hard disk port repairing method comprises the steps that a case management module receives visible state information, sent bya drive, of a hard disk port; wherein the visible state information is acquired by the drive after connection between the hard disk and the storage system is established. And the case management module judges whether one port of the hard disk is invisible or not according to the visible state information. And if one port of the hard disk is invisible, the case management module repairs the hard disk. Therefore, according to the method and the device provided by the embodiment of the invention, the hard disk port with the problem can be discovered in time and repaired. The problem that in the prior art, due to the fact that single-port state monitoring of the dual-port hard disk is lacked, faults of hard disk ports cannot be repaired in time is solved, normal work of the hard disk can be guaranteed, and integrity of stored data and normal operation of data processing services are guaranteed.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method and device for repairing a hard disk port. Background technique [0002] In the era of big data, massive amounts of data are stored in storage devices. As a very important part of storage devices, hard disks have various attributes that are of great significance to data storage. [0003] When a dual-port hard disk is selected for data storage, under normal circumstances, the dual ports of the hard disk are visible to the dual nodes connected to the dual ports of the storage system. The node of the hard disk is not visible, so that only one port of the hard disk is available, which in turn affects the related data processing and storage services. In the prior art, there is a lack of port monitoring for the hard disk, and it is impossible to detect the port failure of the hard disk in time and quickly repair or replace the hard disk, which affects the integrity of data s...
