Thank you Jarrod.
I have added the second mac information to the node.
Also, before i saw your email - i had disabled network booting from the
second interface
Now, I see the following messages in the logs, and the console does not
show up anything useful. After some time, the system just reboots.
DHCPDISCOVER from 6c:ae:8b:20:d5:33 via eth2: booting disallowed

I will try changing netboot to xnba, and check if it performs as expected.
Thank you,

Discovery should have disabled the second nic or assigned the intended
address. To manually do so, nodech m2 mac.mac='6c:ae:8b:20:d5:32|
6c:ae:8b:20:d5:33!*NOIP*' then makedhcp.
FYI, you could also have left netboot=xnba and the 'right' behavior would
have been observed (the firmware would never actually attempt the second
nic).

interfaces
Hello All,
xCAT server in one of our cluster environments is running with version :
2.7.4
This is a prebuilt xCAT cluster from IBM, and i really do not want to
update this test environment as of now.
Issue : ( Node constantly goes into discovery genesis kernel and does not
install OSimage )
I have followed the following steps:
nodeset m2 osimage=centos6-x86_64-install-bluefin-mgmt
rsetboot m2 net
rpower m2 boot
However, the node does not recognize that it has to install the above
OSimage. Instead, it goes into the discovery mode, everytime.
I had verified the tftpboot files, and also the dhcpd leases values. The
leases file clearly mentions that m2 node mac address
(6c:ae:8b:20:d5:32 ) should load pxelinux.0 file. I do not find an issue
with it.
After some analysis, i realized that the node is actually trying to dhcp
from "both" of the ethernet interfaces that are present on the server
with mac addresses:
6c:ae:8b:20:d5:32 and 6c:ae:8b:20:d5:33
6c:ae:8b:20:d5:32 has the node discovered with its definition.
However 6c:ae:8b:20:d5:33 does not have a node defined with it, which is
leading to node discovery and the node goes into genesis kernel with ip
address from the dynamic range.

Is there anyway, that we could prevent this from happening.
Is it possible to use just one interface for tftp and dhcp look up.
It is also possible that, i do not understand the issue correctly. Please
advice.
Thank you,
Lohit
