Get the reference to the root of the services tree: Locate the service that manages the storage domains and use it to search for the storage domain: Locate the service that manages the data centers and use it to search for the data center: Locate the service that manages the data center where you want to attach the storage domain: Locate the service that manages the storage domains that are attached to the data centers: Use the "add" method of service that manages the attached storage domains to attach it: Wait until the storage domain is active:
# Get the reference to the root of the services tree:
