Oh, that's nice.

EVA is the name of the machine; HSV is the SCSI model name, right?
[Reilly, Stephen (MRO)] Correct, presented both for reference

What about the old MSA ones? Is there a firmware upgrade available?
If so, will the name change there, too?

			 Vendor Id: 		Product Id: 
MSA1500 A-A -      "HP      "		      "MSA VOLUME      "

MSA1000 A-P - 	 "COMPAQ  "			"MSA1000 VOLUME  "
MSA1500 A-P -      "COMPAQ  "			"MSA1000 VOLUME  "

I was under the impression that the name would stay the same. If that's 
not the case then of course we should match onto the name.

Please check the attached patch if it updates the hwtables correctly.
