Abstract

The invention provides an LUN integration method used among different RAID groups so as to integrate the two RAID groups. The method specifically comprises the following steps that firstly, an LUN0 is established in the first RAID group; secondly, an LUN1 is established in the second RAID group; thirdly, an LUN2 is established to point to the unoccupied space of the first RAID group and the second RAID group; fourthly, integration of the LUNs is achieved. According to the method, any two different RAID groups are integrated so that a large-capacity LUN can be additionally provided for a system, the system utilization rate is increased, and the problem that an existing magnetic disk space is low in space utilization rate is solved.

Description

technical field [0001] The invention relates to the technical field of virtualized storage, in particular to a method for integrating LUNs among different RAID groups. Background technique [0002] With the continuous popularization of network and information technology, the amount of data generated by humans is increasing exponentially, and various applications are also increasing, which requires effective use of existing equipment and storage space. How to effectively utilize and manage storage space is an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to provide a method for integrating LUNs among different RAID groups, which is used to solve the problem of low utilization rate of existing storage space. [0004] The technical solution adopted by the present invention to solve the technical problems is: a method for integrating LUNs between different RAID groups, which is characterized in that two groups of RAID ...
