Actually it's not all that odd. The nodes I'm working with are white box nodes so the FRU stuff is blank on purpose. Luckily these are test nodes so I can take all the time I need. I set the right FRU fields and xCAT picked everything up without an issue.
I'm now reading through code seeing how switch discovery works and if I can manage to get it to look for serial and auto assign based on that.
The use case is that we do a lot of integration and testing and already scan serials. We don't leave an image on the machines and the switches end up configured for the client. Since we already have the serials, in order, per rack, configuring top of rack switches twice can be quite a bit of added time that could be avoided. I can generate stanza files off the serial scan and pre add every node with the right name. If I can get be discovery to auto associate the nodes them that's one less step. If I can't then I'll write a script to go through a stanza file and fix it up nice and neat and go that route. I'm hoping for the prior but I'm not a Perl guru, I can read and modify but that's with looking things up.
Getting the serials set on my test nodes was a good step in the right direction.

Yeah, it can get a little weird digging into that part of it in a cross-vendor way. The switch discovery was intended as one of the more cross-vendor tolerant modes of getting the job done.

And after getting everything working the Intel Nodes I testing with don't have a machine type or serial number that can be identified by xCAT. I've some thinking to do about this one now.

For reference, one thought was that the gathering of the serial numbers could follow from the switch discovery, skipping tag scan in if that was desirable.
In the current circumstance:
[root@odin ~]# nodediscoverls
UUID NODE METHOD MTM SERIAL
5CD1216B-5C37-11E1-BA0C-5CF3FC6E49C8 undef undef 8737AC1 23XXH29
# nodediscoverdef -u 5CD1216B-5C37-11E1-BA0C-5CF3FC6E49C8 -n n1
There are some other things coming….

Subject: [xcat-user] MTMS Discovery Questions
I am working on getting MTMS up and running as it fits our use case very well. We do a large volume of nodes that are shipped out to customers and all we are responsible for is testing. Scanning tags for serial numbers is already part of the process so getting a list of serial/position is much easier than configuring top of rack switches and doing switch/port discovery. I am curious as to why this method can't be used with pre-defined nodes as switch/port discovery can.
What I'd like to be able to do is use the serial number/position file that I have to predefine the nodes and have them completely setup during discovery. Will this be an exercise in futility and will I be better off just developing scripts to handle the discovered nodes? I am guessing, from reading the docs, that I'll be scripting a chunk of this process but I thought it wouldn't hurt to ask the hive mind before I dived in and broke out the python.
