The Repository object displayed in the Explorer tree has three available actions in the right-click menu:
Discover VM Images: Use this action on a newly discovered or newly created repository to populate it with the VMs residing in the mapped datastore location.
Discover Disks: Use this action to discover ISO disks stored in this repository.
Delete: Use this action to delete the Repository object from the Explorer tree in the Orchestration Console.
Before you delete the Repository object, you need to delete all the VMs contained in that repository; otherwise, an error message is displayed.
Rename: Use this action to rename the Repository object. For more information, see Section 10.8, Repository Object Naming and Renaming.
