If you don't know what an MSA1500 is nor what hp_sw does it's probably not a good idea to have it. Why? scsi_dh_hp_sw is used also for dec/compaq ESA12000 and RA8000 arrays with HSG80 controller. And in HP MSA 1000/1500 and EVA 3000/5000, with old firmware. EVA? I sincerely doubt that. Do you really have an example for that? Anyway. Point here is, these are _really_ old SCSI parallel arrays. And the failover command is _really_ stupid (just send a START STOP UNIT to the passive path). As this has a tendency to interfere with normal operation I prefer to _NOT_ have it loaded per default; in fact, I'm on the verge of removing it altogether.
