Does cinder exposes the wwn of volume? Either through CLI or REST API?

No, I'm asking about the LUN wwn.

so the Fibre Channel World Wide Name of the target that has a LUN?

No, every LUN created on the storage array will have wwn assigned. I'm asking about individual lun's wwn. Not the target array's wwn(fc) / iqn (iscsi )

Nova exposes the WWPN of the HBA it uses to attach LUNs, it does this like the following: https://review.openstack.org/#/c/19992/ and os-brick can be used to review that information: http://lists.openstack.org/pipermail/openstack-announce/2015-September/000581.html (http://lists.openstack.org/pipermail/...) However I am unable to determine the entirely of the way one would use API calls or Client calls to determine this information and I've also been unable to find this info in logs.
