2.8.2. I am already using confignics for configuring the additional
interfaces, perl is already included in our package list so the fact
that it's using perl is not a big deal.
I hadn't thought of using it for eth0 as well. Should confignics be
considered a replacement for hardeths in the future?

Which release of xCAT you are
using? In the latest releases xCAT added the postscript
'confignics' to help configure the nics for compute node. It
could fit your requirement to configure nics for stateless
node. But confignics postscript only works in 2.8.3 to support
stateless (implemented with bash) since the one which released
before 2.8.3 was implementation with perl, but perl is not a
default package which installed for stateless node.

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.

[xcat-user] missing -i flag 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!
