Storage Virtual Machine Configuration Inconsistency Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In storage network environments, synchronization of configuration data between storage clusters for disaster recovery often fails, leading to configuration inconsistencies, which can result in errors, security issues, and access failures during failover scenarios.
Innovation Solution
A system and method for identifying configuration inconsistencies between storage virtual machines across clusters by comparing the configuration data of a first storage virtual machine with its replicated counterpart in a second storage virtual machine, notifying clients of differences to facilitate corrective action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration data is replicated from the first storage cluster to the second storage cluster for disaster recovery, then data availability and system reliability are improved, but configuration inconsistencies may occur between clusters leading to errors and security issues
Solution Approach 1:
The system implements a feedback mechanism by continuously monitoring and comparing configuration data between the first storage virtual machine and the second storage virtual machine. When inconsistencies are detected in replicated configuration data, the system generates notifications to alert administrators, enabling them to correct discrepancies and maintain configuration consistency across clusters for reliable disaster recovery operations.
2Manufacturing precision
If configuration mirroring data is transmitted from the first storage cluster to the second storage cluster, then configuration synchronization is improved, but transmission failures may result in stale or incorrect configuration data
Solution Approach 1:
The system performs preliminary verification by comparing configuration data before and after replication operations. By proactively checking for inconsistencies between the first storage virtual machine and the second storage virtual machine before failover occurs, the system can identify and alert administrators to potential transmission failures, preventing the use of stale or incorrect configuration data during disaster recovery.
3Adaptability or versatility
If configuration data is replicated across storage clusters, then system availability during disasters is improved, but undetected configuration differences may cause access failures and security breaches
Solution Approach 1:
The monitoring system provides continuous feedback by comparing configuration data between clusters and generating notifications when inconsistencies are detected. This feedback loop enables administrators to identify and correct configuration differences before they cause access failures or security breaches during failover operations, ensuring safe and reliable disaster recovery execution.

AI summary
One or more techniques and/or systems are provided for identifying configuration inconsistencies between storage virtual machines across storage clusters. For example, a first storage cluster and a second storage cluster may be configured according to a disaster recovery relationship where user data and configuration data of the first storage cluster are replicated to the second storage cluster so that the second storage cluster can takeover for the first storage cluster in the event a disaster occurs at the first storage cluster. Because replication of configuration data (e.g., a name and size of a volume, a backup policy, etc.) may fail for various reasons, configuration of the first storage cluster is compared to configuration of the second storage cluster to identify a configuration difference (e.g., a new size of the volume at the first storage cluster may have failed to be replicated to a replicated volume at the second storage cluster).
