Orchestrator Integration: Automation Workflow
Goal: Automate vsan stretched cluster configuration - site affinity and failure scenarios configuration and validation to reduce manual effort and ensure consistency across environments.
Workflow steps (VMware Aria Orchestrator)
• Create a workflow: 'vSAN vSAN Stretched Cluster Configuration - Site Affinity and Failure Scenarios Automation'
* Inputs: clusterName (string), configParams (object)
* Step 1: Query vSAN cluster configuration via vCenter API - collect storage policies, capacity utilization, performance baselines
* Step 2: Validate prerequisites from KB vsan-stretched - check version compatibility, hardware requirements, feature dependencies
* Step 3: Implement configuration changes through vSAN management API with validation at each step
* Step 4: Execute health checks post-configuration - run vSAN health service tests, verify storage policy compliance, check resync status
* Step 5: Generate capacity planning report - project future growth, identify optimization opportunities, recommend scaling strategy
* Step 6: Update documentation in CMDB with new configuration state, KB reference, validation results, timestamp
Expected outcome
Automated vSAN storage configuration management reduces manual effort, ensures consistency with KB guidance, provides validation and documentation for compliance.
