Hannes, can you give a quick yes/no on the approach of the attached
patch?  The address of the HBA is given by a wwn property or, in the
lack of one, by an increasing index similar to the one used for MAC
addresses.  The address of the disks is also given by a wwn property or,
in the lack of one, by combining the HBA address with the target number.
