We could rework iscsi-manipulation code into another behavior. For exmaple, Dell PS-series SAN exports each volume in separate target, lun 0. So we can login into this target in activate_volume() and logout in deactivate_volume(). See my plugin for these storages: https://github.com/mityarzn/pve-storage-custom-dellps
Also, there's note about bug in debian's multipath-tools in plugin's README.

That way we can have LUNs only on hosts, where they're needed. Except some cases where PVE does not call deactivate_volume() for some reason (I think these are bugs?).
