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
