[rescue] Cert Testing, was Re: Just a thought

[Steve Hatle]

Way back, when we bought our Tricord (don't ask) I went to their Field 
Engineer class.

Besides all the book stuff, they had two "practical sessions".

In the first one, they assigned two people to one machine, and you had 
to take it apart into all it's components (CPU cards, memory cards, 
disks and disk chassis, power supply units, power controller, backplane, 
etc.). Then, you had to go to a different machine than the one you took 
apart, and put it all back together so it booted and ran correctly.

The second test was while we were at lunch, their techs went into each 
of the six machines, and introduced some kind of failure. You had to 
correctly diagnose 4 of the 6 machines. Pretty specifically, too. Not 
"the controller can't talk to the disks", but "Fuse two on disk 
backplane one is failed". The icky one was where they randomly 
re-arranged a bunch jumpers on the CPU boards. Nothing was apparent by a 
quick visual inspection- you had to have the right diagram for that 
particular rev of board in front of you to know if they were right or 
wrong.
