The iSCSI protocol/standard provides no mechanism for remote creation
of new LUNs. It all has to be done on the NAS administration console,
whatever they may be, or via vendor-specific APIs. One day we would
like to integrate some of these vendor specific APIs into libvirt's
iSCSI driver to improve this situation, but that's some way off...

I described one way todo this here:

YMMV depending on your iSCSI server
