Method for reducing faults of independent redundant disk array

The invention provides a method for reducing faults of an independent redundant disk array. The method comprises the steps that a shake or impact suffered by the independent redundant disk array are detected at a certain frequency; when each shake or impact suffered by the independent redundant disk array is detected, the independent redundant disk array can be managed by a first management strategy if the shake or impact does not exceed a first threshold value; if the shake or the impact exceeds the first threshold value, a second management strategy can be called to manage the independent redundant disk array; and after the second management strategy is called to manage the independent redundant disk array, a disk is made to drop off line from the independent redundant disk array if the disk in the independent redundant disk array makes no response under the second management strategy. The method for reducing the faults of the independent redundant disk array provided by the invention has the advantages tha
