I guess you might need to port one of the other iSCSI-based drivers (e.g. lefthand) to use whatever creation/deletion/access control mechanisms your Dell SAN uses... This does not look to be a significant amount of work, but such commands aren't generally standardized so would need to be done for your specific SAN.

I also understand that there is another process for using an HP lefthand SAN or solaris iSCSI setup, whereby nova-volume can interact with APIs for volume creation on the SAN itself. I have a dell iSCSI SAN, and I can see that I'd be able to mount a LUN from the SAN on my nova-volume node, then go through the documented process of creating an LVM on this LUN and having nova-volume re-share it over iSCSI to the compute nodes, but what I'm wondering is whether I can have the compute nodes simple connect to the iSCSI SAN to access these volumes (which would be created and managed by nova-volume still), rather than connect each compute node to the iSCSI target which nova-volume presents? I imagine with this setup, I could take advantage of the SAN's HA and performance benefits. Hope that makes sense..
