Actually, it occurs to me to ask: Can Jordi's presentation be uploaded to
the sourceforge wiki so that it can benefit more people?

Hi John,
I had a similar experience to you in the matter of the documentation only
taking me so far and the rest was left to my "real world" implementations
(mostly troubleshooting when things didn't go as expected). xCAT has
dependencies on many other things that are assumed to be working already
(like SNMP on switches if you are using network discovery, to take one
example among many), and so has many moving pieces. I too found the
Sumavi documentation useful to an extent. I have over 20 pages of notes
in a google doc of my own observations on specific xCAT things I have run
into.
To add to your list of documentation though, I discovered this little gem
of a presentation by Jordi Caubet working at IBM Spain given in 2011:
http://www.bsc.es/media/4373.pdf. It may not cover everything you need
but I actually found that it had details about xCAT that you cannot find
elsewhere. For example on slide 56 he shows the exact order that
deployment template scripts are parsed in in a very useful picture, which
is information not even to be found in the sourceforge wiki (maybe
someone reading this can fix that?).
Anyway, maybe that will give you something you are looking for.
Regards,
Josh Nielsen

This is a good start. It's a little bit old and does some things in a
different way than I would, but the overall information in it is great:

I'm working on a government contract to support an HPC environment
that uses xCAT. I've spent over 7 1/2 months working with a
document that really doesn't say much more than how to get
hardware support that was produced by the vendor who did the
initial installation. I've also used what I could find in Google.
But, to tell you the truth, none of it really seems to be all that
"good". It tells me about this or that implementation, and can be
adapted to meet my needs, but it takes time and effort that seems
to be more than should be necessary.
Now, it may be better than it once was. I'll give you that. But
I'd like to know if there is a good published document out there I
can look for, electronic or pulp, that I can use to give me better
guidance? What is there out there? And are there any sites you've
run across that might help me to fill in the gaps in my current
knowledge?
Don't get me wrong. I really do appreciate the pieces of
documentation I've found. I'd just like to find something that
would help me to be able to tie it all together better.
Sincerely,
John W. Hosie III
