Embodiment Construction

[0029] The technical solutions provided by the present invention will be further introduced below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, the present invention provides a method for processing disk roaming in a storage system, including:

[0031] Step 101, when disk roaming occurs in the storage system, update the preset drive letter and / or slot of the disk when no disk roaming occurs to the current drive letter and / or slot of the disk;

[0032] Step 102, construct redundant disk array (RAID) information according to the updated drive letter and / or slot and the RAID information when no disk roaming occurs.

[0033] In the method provided by the present invention, when disk roaming occurs in the storage system, the drive letter and / or slot when no disk roaming occurs is updated to the current drive letter and / or slot of the disk, and then according to the updated drive letter and / or slots and RAID information when disk roaming does ...

Abstract

The invention provides a method and a device for processing disk roam in a storage system, which relates to the field of storage. The method comprises the following steps of: when a storage system generates disk roam, updating the drive and / or the slot position of a preset disk which does not generate the disk roam into the current drive and / or the slot position of the disk; and according to the updated drive and / or slot position and PAD information when the disk roam is not generated, constructing the information of Redundant Arrays of Inexpensive Disks (RAID).

Description

technical field [0001] The invention relates to the field of storage, in particular to a method and device for processing disk roaming in a storage system. Background technique [0002] A mid-to-high-end storage system usually consists of multiple controllers and multiple disk cabinets. Each controller is connected to multiple disk cabinets (Just Bundle Of Disks, JBOD). Each disk cabinet has multiple slots. One disk can be deployed in the slot. If the user removes the disk from the slot and puts it in the wrong slot, or inserts or removes the disk while the computer is powered on, there will be a discrepancy between the disk and the drive letter on the user interface. This phenomenon is a disk roaming problem. Once the problem of disk roaming occurs, building a redundant array of independent disk (Redundant Array of Independent Disk, RAID) on the basis of the disk using a disk letter will cause problems, causing users to be unable to access data in the disk. [0003] In or...
