Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0022] Such as figure 1 As shown, the implementation steps of the disaster recovery recovery method for the disk array in the embodiment of the present invention are as follows:

[0023] 1) When creating a disk array, pre-connect and set up a backup disk;

[0024] 2) Set the disk array failure counter and trigger count threshold, detect whether the disk array fails when the operating system is powered on, if a failure occurs, add one to the disk array failure counter, and clear the disk array failure counter if no failure occurs;

[0025] 3) After the operating system is powered on, compare the disk array failure counter with the trigger count ...

Abstract

The invention discloses a disaster recovery method for a disk array. The disaster recovery method includes the following steps: 1), connecting and arranging a backup disk in advance during establishing of the disk array; 2), arranging a disk array fault counter and setting a trigger count threshold value, detecting whether the disk array has faults or not during starting of an operating system, if yes, adding one to a value of the disk array fault counter, and if not, resetting the disk array fault counter; 3), comparing the value of the disk array fault counter and the trigger count threshold value after starting of the operating system, judging whether or not a faulted disk can be replaced by the backup disk according to disk array types and disk array fault types if the value of the disk array fault counter is larger than or identical to the trigger count threshold value, and if yes, replacing the faulted disk by the backup disk and executing disk array reestablishment. The disaster recovery method has the advantages that the method is high in reliability, free from manual intervention, simple to operate and convenient to use.

Description

technical field [0001] The invention relates to the storage field, in particular to a disaster recovery method for disk arrays. Background technique [0002] Existing disk arrays lack disaster recovery methods. Once a disk array fails, the disk array must be repaired, rebuilt, or even initialized. However, these processes all rely on certain professional knowledge. For many end users, because they are not familiar with or ignore the warnings issued when the disk array fails, they may miss the repair of the disk array and may cause data loss. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a disaster recovery recovery method for disk arrays with high reliability, no manual intervention, simple operation and convenient use. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A kind of disaster recovery method for disk ar...
