We have about 8000 nodes that would be sitting on DHCP and trying to
update their leases whenever it expires - that's a lot of
unnecessary traffic and log entries. So we utilize hardeths to turn
the interface into a statically-assigned IP to prevent that.

you want to set the static ip for a stateless node?

from genimage --dryrun
Thanks Xiao,
The issue wasn't that the nodes weren't booting, just that
dryrun wasn't giving me the interface flag that is required.
Unfortunately genimage still seems to need this flag to produce
the /etc/sysconfig/network-scripts/ifcfg-eth0 file. Hardeths
needs this file to be able to correctly create a static
interface file. Am I missing something there?
I also found that the "nodebootif" option in osimage was what I
was looking for to give me the missing "-i" flag.
Thoughts? Is there a way to properly get the needed
/etc/sysconfig/network-scripts/ifcfg-eth0 file into the image
without using the "-i" flag? Or a way to get hardeths to
cooperate when the ifcfg-eth0 file isn't there?

Generally, xCAT recommends to
use the mac address to specify the boot network interface.
That means during the genimage, no specific interface needs be
specified, but configure the mac address for node and set
installnic=mac so that during the boot of stateless image, the
interface which specified with the specific 'mac' will be
used.
So the problem was that did you configure your node correctly
with the mac and installnic attributes I guess.
If you really want to specify the network interface by
yourself, just use the -i flag anyway.
Thanks

missing -i flag from genimage --dryrun
Hi all,
I am following this guide for generating a CentOS 5 image on
a CentOS 6
management node:
http://sourceforge.net/apps/mediawiki/xcat/index.php?title=Building_a_Stateless_Image_of_a_Different_Architecture_or_OS
When I am running the "genimage --dryrun $osimage", it
produces output
that does not include the "-i" flag that specifies $prinic,
which is
then used for creating the
/etc/sysconfig/network-scripts/ifcfg-$prinic
file by the genimage script. As a result, the image that is
generated is
missing ifcfg-eth0 file, and hardeths fails on the node.
Am I missing configuration somewhere that would give me the
missing -i
flag for my genimage line?
Thanks!
