3.8. Attaching a Storage Domain to a Data Center

# Get the reference to the root of the services tree:

search for the storage domain:

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:

  OvirtSDK4::StorageDomain.new(
    id: sd.id
  )
)

# Wait until the storage domain is active:
