Sun Blade 2000 Swapping hard drives

We have a SUN Blade 2000 that has one 72G hard drive in it.
When we power on the Blade it does nothing.  Doesn't boot, no display, nothing.  But the fans do come on.

So we have a spare Blade 2000 that does work.  I want to take the hard drive out of the one blade and place it in the spare.  Everyone here is saying it won't work.  Says the blade is looking for a different hard drive.

What they are saying seems to be like the issue the Netra 240 and Netra 20s have when swapping hard drives where you have to set the environment to nothing and clear it all out and then boot off the disk.

So my questions is:
How do I get a Sun Blade 2000 to boot off of the hard drive from a different system but the exact same hardware?

Thank you

Just plug the disk and boot?
normally it is juggling with ls and setenv boot-device if it does not boot on the spot.

That is what I said, but everyone here is saying no that won't work.  I'll give it a try.

How do I check the dial of the SCSI ID and how do I make them the same?

I may need to clarify the question.  I can't find the SCSI ID of the hard drives in the system they are currently in because that system will not even perform a POST.  The Sun Blade screen doesn't even come up.

I am taking the hard drives out of the old system and placing them in a new one.  Just want to try and avoid any issues with doing it.

Everyone here is saying it can't be done.
Your machine does not have retractable configuration card. MAC addresses will change.
If you are lucky (like both machines from factory) you get same SCSI ID and it will boot just fine.
