Hi, Like you said it depends on your Cinder and OS-Brick versions, and the open-iscsi package will be different depending on your distro, for RHOS 7.4 this is iscsi-initiator-utils version 6.2.0.874-2 or later. Things working fine may also depend on your multipath and Cinder/Nova configuration as well as LVM filters (if your deployment can have images that have LVM). I think that's all that need to be properly setup.
