Before managing the objects in your vSphere inventory by using Orchestrator and to run workflows on the objects, you must configure the vCenter Server plug-in and define the connection parameters between Orchestrator and the vCenter Server instances you want to orchestrate.
You can configure the vCenter Server plug-in by running the vCenter Server configuration workflows from the Orchestrator client.
To manage the objects in your vSphere inventory by using the vSphere Web Client, make sure that you configure the Orchestrator server to work with the same vCenter Single Sign-On instance to which both vCenter Server and vSphere Web Client are pointing. You must also ensure that Orchestrator is registered as a vCenter Server extension. You register Orchestrator as a vCenter Server extension when you specify a user (by providing the user name and password), who has the privileges to manage vCenter Server extensions.
