Hi Robin,

Are you sure the tftp-server is listening and there's not a firewall (host or network
based that's blocking communication to that tftp port)?

Does the client system get a dhcp address from the server?

Cheers,
Harry

Hi Guys,

I have been using cobbler for a few months now and it has worked very
well for us.  However, we have been only building a few servers at a
time and my current process of having our SA's run a "cobbler system
add" command for each server has worked just fine.  I now have a
requirement to build a cluster with 50+ nodes and was wondering how to
automate this as much as possible.  Has anyone out there already done
something similar?  If so, how did you approach this?  I would hate to
tell someone to run the cobbler system add command for 50 servers.

Thanks in advance for your help with this!

Regards.

I suppose you have a list of the MAC addresses and power management data
(and maybe
IP addresses) of the 50+ nodes. Simply create a Python script which
creates the missing
system data (eg name) automatically and uses Cobbler CLI / XML-RPC
interface to add the
systems to Cobbler.

Actually I don't have the mac addresses handy.  Would have to login to
the ilo/idrac of each server and grab the mac which is very time
consuming.  I do have all the hostnames and ip addresses defined in
dns.  Is there a way for me to get the bare metal hardware to tell the
cobbler server its mac addresses and auto register somehow.  From
there maybe I can write a shell script to populate the other needed
info.

Thanks.

Hi!

Yes, all dhcp/dns/tftp parameters were ok.

I juste succed in depoyling nodes, the problem was the path of the repos... 

Thank's and sorry for asking your help for that ><

Write a script to do that? expect/pexpect may be helpful.

If your bare metal hardware is in the same LAN of the Cobbler server,
you can use "arp -a"
after pinging the bare metal hardware from Cobbler server to get its MAC
address.
If Cobbler server is not in the same LAN, you could split this in 2
steps: run a MAC address
discovery script in a system which *is* in the same LAN of the bare
metal hardware and then
add the systems to Cobbler.
