Ah, that's news to me.
How does the product name change?
>> The firmware will change the name
My contacts at HP Boeblingen said that the revision number indicated the 
behaviour.
What are the names of the fw using START_STOP_UNIT?
>> HSV100 and HSV110 EVA3000/5000
And what are those for using ALUA?
>> HSV101, HSV111, HSV200 and HSV210 EVA 3000/5000  EVA4000/6000/8000

And irrespective of this I think matching by revision is still a valid 
addition to the hardware table mechanism.
