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

Embodiment

[0011] Hereinafter, in conjunction with the drawings, embodiments of the method and system for responding to a failure condition of a data storage unit of the present invention are detailed.

[0012] figure 1 That is, the application structure and the basic structure of the object-oriented component model (object-oriented component model) of the data storage unit failure response processing system of the present invention (the part included in the dashed box as indicated by the reference number 100) is shown. As shown in the figure, the data storage unit failure condition response processing system 100 of the present invention is in practical application coupled to an access control interface 30, and the access control interface 30 is coupled to at least one computer system 10 and at least one The data storage unit 20 provides a data storage unit failure status response processing function for the data access action between the computer system 10 and the data storage unit 20, tha...

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 method and system for responding to a failure condition of a data storage unit, which can be applied to an access control interface, and the access control interface is coupled to a computer system (such as a computer system). Between the server group) and a data storage unit (for example, a redundant independent 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 plug removal, system composition change, etc.), a special response processing procedure can be performed on the failure condition, so that the access control interface will occur in the failure condition The access command received at the time will not result in an incorrect processing result. Background technique [000...
