Patent ID: 7359833

Claim:
An information processing system which communicates with a storage system, comprising: a program storage area which stores a plurality of computer programs; a fault storage area which stores fault data relating to a fault occurred in the storage system; and at least one processor which reads and executes at least one computer program from said program storage area, wherein said plurality of computer programs comprise: an information issuing program which issues information; an intermediate processing program which receives and converts the information issued by said information issuing program into a different format interpretable by the storage system, and then outputs the converted information to an information filter program; and said information filter program which, when detects information received from the storage system is anomaly information regarding an anomaly occurred in the storage system, prior to notifying said information issuing program of the anomaly, outputs and then re-outputs said anomaly information at least once to the intermediate processing program, and when the anomaly continues even after said one or more re-outputs, notifies said information issuing program of the anomaly, wherein the information filter program receives the converted information output by said intermediate processing program, judges whether fault data is stored in said fault storage area, either passes said converted information to said storage system when judging said fault data is not stored, or notifies said intermediate processing program of the anomaly in response to reception of said anomaly information without outputting said anomaly information back to said storage system when judging said fault data is stored in said fault storage area.
