Hi,
My diskful install process gets stuck in the post-install process on the
`updateflag.awk` script. I understand that this happens when the IP of the
node doesn't resolve to a name.
However, what bothers me is that this is caused by the assignment of 2 IPs
to the `ksdevice`.
The DHCP server deletes the ddns entry for the first IP lease, and assigns
the details of the 2nd lease in the DNS server. However, the updateflag.awk
script is communicating via the primary IP (it cannot select the secondary
IP as the local interface to use).

When I check in the console on the node (the 2nd console, Ctrl-Alt-F2), I
see 2 addresses assigned to the `ksdevice` (Both the IPs assigned to MAC
00:25:90:14:f8:18 : 10.2.72.9 and 10.2.72.10).
This is done in the %post section of the kickstart file:
[root@xcatmn01 tmp]# grep 'dhclient ' /install/autoinst/xcatsn01
dhclient eth0
The primary nic is `eth1`, and the template (
xCAT-server/share/xcat/install/scripts/post.rh.common) has these line:
[samveen@development xcat-core]$ git blame
xCAT-server/share/xcat/install/scripts/post.rh.common |tail -n +38 |head
-n 7
53374908 (immarvin 2014-05-30 03:12:08 -0700 38) IP=$(ip addr show dev
$PRINIC | grep inet | grep -v inet6 | awk '{print $2}' | head -n 1 | awk

8168b22e (ligc 2012-03-23 08:26:38 +0000 39) if [ -z $IP ]

awk -F '/' '{print $1}')
8168b22e (ligc 2012-03-23 08:26:38 +0000 44) fi
Given that this script sets the variable `PRINIC`, Line 4 should be as
follows(as can be seen from line 43):
--- a/xCAT-server/share/xcat/install/scripts/post.rh.common
+++ b/xCAT-server/share/xcat/install/scripts/post.rh.common

then

+ dhclient $PRINIC
#IP=$(ifconfig $PRINIC | grep inet | awk '{print $2}' | awk -F:

This fixes my problems.
