Storage Fault Management System Using Matching Rate Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current storage system management technologies face challenges in identifying the root cause of faults and providing effective recovery procedures, as they rely on static recovery procedures and lack association with solving target troubles, making it difficult to recover only the faulty component and operate components with and without faults accurately.
Innovation Solution
A management system that analyzes fault information to specify a matching rate between occurring faults and registered faults, using knowledge base information to display relevant recovery procedures and scripts, enabling targeted fault recovery by correlating fault details with recovery processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static recovery procedures are used that simply combine the order of components, then the procedure is easy to implement, but it fails to specify the root cause component and cannot provide appropriate recovery procedures
Solution Approach 1:
The system implements feedback by analyzing fault notification information and correlation information to dynamically determine which components should be recovered. The determination unit receives fault notifications, correlates them with component relationships, and provides feedback on which specific components require recovery, rather than using static predetermined procedures.
Solution Approach 2:
The patent replaces mechanical/manual analysis of fault relationships with automated information processing. The determination unit automatically analyzes correlation information and fault notifications to identify root cause components, substituting human judgment with systematic information processing that can handle complex component relationships.
2Reliability
If all components in fault state are recovered, then complete system recovery is achieved, but unnecessary recovery operations are performed on components that are not the root cause
Solution Approach 1:
The system extracts and identifies only the necessary root cause component(s) from the set of all faulty components. By analyzing correlation information, the determination unit separates the essential recovery target (root cause) from non-essential components, recovering only what is necessary to resolve the fault.
Solution Approach 2:
Instead of recovering all faulty components (excessive action), the system performs partial recovery by targeting only the root cause component(s). This partial action is sufficient to resolve the fault condition without the waste of recovering components that would work fine after root cause resolution.
3Device complexity
If fault analysis information is not associated with solving target troubles, then the system structure is simple, but it is difficult to solve troubles using correlation with the trouble
Solution Approach 1:
The correlation information structure serves multiple functions: it identifies component relationships, determines root cause components, and guides recovery operations. This universal information structure handles various fault scenarios and component relationships through a single coherent framework.
Solution Approach 2:
The system pre-establishes correlation information between components before faults occur. This preliminary structuring of relationships enables rapid fault analysis and root cause identification when faults occur, without requiring complex real-time analysis of component interactions.

AI summary
A management system of a storage system specifies a matching rate between an occurred fault and each of one or more registered faults on the basis of fault analysis information which is information indicating, for each fault, a relation between a fault in the storage system and a fault detail including knowledge base information. Each of the one or more registered faults is a fault in which the information is registered in the fault analysis information. The management system displays information related to the registered fault including the specified matching rate with respect to each of the one or more registered faults.
