Those should be expected. The SCSI layers are trying to configure the
devices (read capacity, partition tables etc). The dm-hp-sw module
is not in that path so it can't do anything about that. They should be
harmless. 
 
This is an architectural artifact of doing the multipathing above the
SCSI layer.
