Infrastructure Software

I am following the wartak document located under http://www.oracle.com/technology/pub/articles/wartak-rac-vm.html

"Build Your Own Oracle Extended RAC Cluster on Oracle VM and Oracle Enterprise Linux"

I am hitting a problem when bringing up the rac1 and rac2 eth2 network devices.

E.g. rac2 eth2 shares the same I.P. address as iscsi2 :

[root@iscsi2 network-scripts]# cat ifcfg-eth1
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
NETMASK=255.255.255.0
IPADDR=10.98.1.102
MTU=9000

Note above that the address is 10.98.1.102.

As per the document, this is the same I.P. address as rac2 eth2:

[root@rac2 network-scripts]# cat ifcfg-eth2
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
TYPE=Ethernet
DEVICE=eth2
HWADDR=00:16:3E:22:78:26
NETMASK=255.255.255.0
IPADDR=10.98.1.102
MTU=9000

When I start the network, I get the following error:

[root@rac2 network-scripts]# service network start
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]
Bringing up interface eth1: [ OK ]
Bringing up interface eth2: Error, some other host already uses address 10.98.1.102.
[FAILED]

I believe I am following the document to the letter but I cannot get the device to come up without taking down the opposite device on iscsi2.

Please help.

Thanks.
