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
