Problems solved by technology

However, in the case that the failed independent redundant disk array has not returned to the normal online state, the result of the retry will also lead to wrong processing results, which will consume unnecessary processing time, thus reducing the overall network information processing efficacy

Abstract

The invention is a failure response processing method and system for a data memory cell, assorted with an access control interface and coupled to at least a computer system and at least a data memory cell, providing a failure response processing function of a data memory cell and the system comprises: failure detection module, access instruction queue module and access instruction reading module; after a data memory cell fails, it registers all follow-up access instructions into a preset queue register region, and waits until the data memory cell return to normal and then in turn processes these access instructions, thus able to avoid wrong processing results and assure the whole efficiency of processing network information.

Description

technical field [0001] The present invention relates to a computer information technology, in particular to a data storage unit failure state response processing method and system, which can be applied to an access control interface, and the access control interface is coupled to a computer system (such as a Between the server group) and a data storage unit (such as an independent redundant disk array), a data storage unit failure response processing function is provided for the data access action between the computer system and the data storage unit, that is, When the data storage unit has a temporary failure condition (such as hot-swappable removal, system composition change, etc.), a special response processing procedure can be carried out for this failure condition, so that the access control interface can be used when the failure condition occurs The access command received at this time will not have an erroneous processing result. Background technique [0002] Redunda...
