cinderlib.objects module

class Connection(*args, **kwargs)

Bases: cinderlib.objects.Object, cinderlib.objects.LazyVolumeAttr

Cinderlib Connection info that maps to VolumeAttachment.

On Pike we don’t have the connector field on the VolumeAttachment ORM instance so we use the connection_info to store everything.

We’ll have a dictionary:

{‘conn’: connection info

‘connector’: connector dictionary ‘device’: result of connect_volume}
