The default workflows for managing vSphere inventory objects are the workflows included in the vCenter Server plug-in workflow library. The vCenter Server plug-in workflow library contains workflows that you can use to run automated processes related to the vCenter Server and host management.
To access workflows in the vSphere Web Client, make sure that you configure at least one running Orchestrator server to work with the same 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 account that has the necessary privileges to manage vCenter Server extensions. For more information, see Installing and Configuring VMware vRealize Orchestrator.
Only a predefined set of vCenter Server workflows are available by default in the context menu. You can associate additional workflows with each vSphere object. See Associate Workflows with vSphere Inventory Object Types.
