Hi Will,
Do you have "dhcpinterfaces" attribute defined in the site table.
Please make sure the interface on the the mn that's in the second domain
is in this attribute.
Did you run makedhcp -n after adding the second domain?
# makedhsp -n
# makedhcp -a
Are there any service nodes in your cluster?
dhcpinterfaces: The network interfaces DHCP should listen on. If it is
the same
for all nodes, use a simple comma-separated list of
NICs. To
specify different NICs for different nodes:
xcatmn|eth1,eth2;service|bond0.
In this example xcatmn is the name of the xCAT MN, and
DHCP there
should listen on eth1 and eth2. On all of the nodes in
group
'service' DHCP should listen on the bond0 nic.
In fact for xCAT mn, you do not have to put the name there if there are no
service nodes. Just "eth1,eth2".
Thanks,
Ling

Subject: [xcat-user] help with second domain
Hello,
I'm trying to configure a second domain in xCAT. I have the interface
configured both with an IP and as a DHCP interface on the master node.
The networks table has been populated and the appropriate fixed IPs for
nodes in that domain have been added to the host file. All the nodes
have been added to the appropriate tables and the lsdef commands work as
expected, as does DNS. However, DHCP does not seedm as willing to
cooperate. The nodes are defined in the leases file without issue, but
there is never a fixed IP assigned to them (there is a dynamic range
defined for this network, but these nodes are not in that range). There
are also times when the MACs are defined in the leases file, but not
with the fixed IPs that are desired. The results seems to be a
discovery loop. makedhcp -q never responds with the appropriate
information. I've also tried defining the nodes in the hosts tables,
which isn't necessary for the default domain. I've also configured a
node for the default domain and everything works as it should. Any info
that will help me resolve this issue would be appreciated. Thanks.
