To preserve data integrity, follow the following shutdown order for the vRealize Automation components:
Shut down the primary vRO appliance. Once the shutdown completes, shut down the secondary nodes.
Shut down the Distributed Execution Manager Orchestrator, Workers, and all the vRealize Automation agents in any order and wait until all components finish shutting down.
Shut down the Manager Service machine. Once the shutdown finishes, continue to shut down additional nodes if they exist.
Shut down the primary web node. Once the shutdown finishes, continue to shut down additional nodes if they exist.
Shut down the primary vRealize CAFÉ appliance. Once the shutdown finishes, continue to shut down additional node if they exist.
Shut down the PostgreSQL and MSSQL virtual machines in any order and wait until the shutdown finishes.
Shut down your SSO appliance, which could be an identity appliance or a vSphere SSO/PSC if this is dedicated for the vRA deployment.
Shutting down the load balancer will be the last step.
