Hi Andrew,
It looks like you are deploying the stateless nodes. For stateless
nodes, the file /opt/xcat/xcatdsklspost will be called on the node. It
will wget all the postscripts and store them under /xcatpost directory.
You can take a look at /install/postscripts/xcatdsklspost file. I do not
know what version you are using, the latest should have the following
order to figure out what server to use for downloading the postscripts.
1. check /opt/xcat/xcatinfo file. look for "XCATSERVER=10.16.0.103". This
file is usually not there when the node first boot up. You can manually
add it to the image if there is only one xCAT server. Just add one line.
2. check XCAT=10.16.0.103:3001 from the kernel command line. You can see
it in the bootparams table. If it is not there, you can add it to
bootparams.addkcmdline
3. DHCP server
Hope it helps.

Subject: [xcat-user] wget from wrong server during netboot
I'm trying a netboot install for the first time, after having a working
xCAT installation for quite some time.
We use a central DNS and DHCP server on another subnet, at 10.101.1.11.
The master xCAT server is at 10.101.4.3.
The netboot progresses to the point where it's running the following
command, at which point it hangs, since our DNS/DHCP server isn't running
ftp:
wget -l inf -nH -N -r --waitretry=10 --random-wait -T 60
ftp://10.101.1.11/postscripts -P /xcatpost --cut-dirs=1
I've grep'd everything I could think of to figure out where it's getting
10.101.1.11 (the DNS/DHCP server address) from for that wget command.
/install/autoinst/nodename doesn't mention it.
lsdef nodename doesn't mention it.
/install/netboot/fedora13/x86_64/compute/rootimg doesn't mention it.
The only mention of it in a dump of all tables is in site.nameservers,
which is exactly where I want it.
Why is wget trying to contact the DNS/DHCP server instead of the master
server during netboot? Any other places I need to look to set this config
correctly?
Thanks.
Andrew
