Here's how I did it in a three node iSCSI cluster...
[root@l82bi121 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
172.23.189.121 l82bi121.lss.emc.com l82bi121
172.23.189.212 l82bi212.lss.emc.com l82bi212
172.23.189.36 l82bi036.lss.emc.com l82bi036
10.10.10.36 node036.gfs node036
10.10.10.121 node121.gfs node121
10.10.10.212 node212.gfs node212
This host also contains two other NICs being used for iSCSI
connectivity.

Subject: running cs on hosts with two NIC's
Hello List,
I'd like to run the cluster suite on computers with two NIC's. One of
them is configured as 10.2.1.1/16, tho other one is our public ip range.
I set up both the public addresses in /etc/hosts. Unfortunately,
/proc/cluster/status states the private ip addresses instead of the
public ones. How can I force cman to use the public addresses and
therefore get the cluster being accessible for other hosts?
Thanks in advance!
Sebastian
