While agree sometimes we have to get on the same page, I see a vendor as a partner in my success.  If the vendor has a different idea, we don't have a problem seeking new vendors.  If that vendor can not help you reach your goals, why squander the company's money?

It is also best to discuss this during the sales cycle.  If we buy X number of nodes, I don't think I need to be spending 2,3 or 4 hours on each of them to upgrade all the firmware-before I can put them to work. I consider that absurd. 

We have also never had an issue with a vendor getting this information to us.  They have to capture it anyway. In fact, we send then a spreadsheet with hostname and they fill in the rest of the information. We get the spreadsheet, I run a script for the that vendor and the DB is populated-a second.  After that, as the nodes are placed in the rack and connected, when power is applied it starts to install!!!  On paper. :)

But is works way more than it doesn't.
