What creates isci volumes?

Hello, I am currently trying to create a kvm manually by copying the kvm command that Nova runs. However I come upon an error saying "could not open disk image" when trying to access isci by /dev/by-path/ip- etc.. Nova is turned off, but doesn't cinder create the volumes? What do I need to regain access to this volume?

View LVMiSCSI cinder backend for RDO Juno on CentOS 7
Actually, if LVMiSCSI backend is properly configured for CINDER then:-

iSCSI target gets created automatically when you launch VM based on Cinder volume, which may be created automatically  during boot up ( boot from image create volume ) or pre-created via glance image by cinder CLI or Horizon interface.  It happens on Storage Node.  iSCSI initiator ( a client of iSCSI Target Server) is running always on Compute Nodes, where VM reside.

I am using Ubuntu 12.04.5 LTS, and I guess my question is does nova initiate the volume?
