Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual methods are used to modify remote replication configurations when adding or removing logical devices, then flexibility in storage group modification is achieved, but system complexity increases and data protection reliability deteriorates due to partial protection and operational disruptions
Solution Approach 1:
The system automatically performs verification, analysis, and modification of remote replication configurations when storage groups are modified. The automated method independently checks replication status, analyzes configuration changes, and executes appropriate modifications without requiring manual intervention, thereby maintaining data protection reliability while enabling flexible storage group modifications
Solution Approach 2:
The system verifies the current remote replication configuration status before modification and performs analysis to determine the appropriate actions. This feedback mechanism ensures that the system understands the current state and can make informed decisions to maintain data protection during storage group expansions or reductions
2Reliability
If automated verification and analysis are performed before modifying remote replication configurations, then data protection reliability is maintained, but processing time and system complexity increase
Solution Approach 1:
The system performs verification and analysis of the remote replication configuration before actual modification occurs. By checking replication status and analyzing required changes in advance, the system ensures data protection is maintained while preparing the modification plan, preventing operational disruptions during the actual modification phase
3Device complexity
If manual modification of remote replication configurations is performed, then system complexity remains low, but resource consumption increases due to operational disruptions and partial data protection
Solution Approach 1:
The system automatically manages the complexity of remote replication configuration modifications through automated verification, analysis, and execution. This self-service approach eliminates the need for manual configuration management while preventing resource waste from operational disruptions and partial data protection, thereby reducing overall resource consumption despite the added automation capabilities

AI summary
Techniques for modifying an application data set may include receiving a request to modify a storage group of logical devices used by an application; and performing processing that modifies, in accordance with the request, the storage group and an existing remote replication configuration. The processing may include verifying that the logical devices of the storage group are protected by remote replication performed in accordance with the existing remote replication configuration; analyzing the existing remote replication configuration and generating analysis information; performing, in accordance with the analysis information and the request, a first modification to the existing remote replication configuration; and performing, in accordance with the request, a second modification to the storage group. The request may add logical devices to the storage group or remove logical devices from the storage group and accordingly modify the existing remote replication configuration.
