Abstract

The embodiments of the present invention relate to a processing method and an apparatus for RAID configuration information and an RAID controller used for an RAID. The RAID comprises a plurality of hard discs, the method comprises the steps of: detecting whether a new hard with information stored therein, not corresponding to the preconfigured RAID configuration information corresponding to the index of the hard disc self; when detecting that a plurality of hard discs are provided with new hard discs, the preconfigured RAID configuration information corresponding to the index of the hard disc self is written into the new hard discs and the new hard discs become one hard disc of RAID. The embodiments of the present invention can avoid the problem that the operation time is too long and the errors easily occur due to that the preconfigured RAID configuration information corresponding to index of hard disc is configured into the new hard discs manually by operators, thereby increasing the reliability of RAID configuration information.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for processing configuration information of a redundant array of independent disks (Redundant Array of Independent Disks, RAID for short), and a RAID controller. Background technique [0002] A redundant array of independent disks (Redundant Array of Independent Disk, referred to as RAID) is a hard disk group (logical hard disk) formed by combining multiple independent hard disks (physical hard disks) in different ways. RAID can use striping (striping) technology to distribute data to each hard disk. Each strip can be regarded as a logical unit (Logical Unit, referred to as LU), which can be represented by a logical unit number (Logical Unit Number, referred to as LUN). To identify. Each logical unit is distributed to a continuous block (block), and after the data is divided into several blocks ranging from 512 bytes to several megabytes...
