If you can point me to a single user of an MSA1500 I'm happy to include it. 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.


Cheers,

Hannes
