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
