Hi, Laohu You shouldn't use cinder attach API to attach a volume to an instance. Cinder attach API worked with Nova attach API, so you should call Nova attach API that will attach volume really. Attach volume is a complex process, it start from Nova side, Nova will interact with Cinder several times via calling different Cinder APIs.
