Dear All,
I have configured Cluster Suite with 2 servers
Server 1 : 192.168.13.110 IP Address and hostname is primary
Server 2 : 192.168.13.179 IP Address and hostname is secondary
Floating : 192.168.13.83 IP Address (Assumed by currently active server)

I have configured Ethernet Channel Bonding in Each Cluster Nodes and 
Channel Bonding Configuration Details are
1) Created bonding devices in "/etc/modprobe.conf" file    alias bond0 
bonding
  options bonding miimon=100 mode=1
2) Edit the "/etc/sysconfig/network-scripts/ifcfg-eth0 and ifcfg-eth1" 
configuration
  DEVICE=eth0
  USERCTL= no
  ONBOOT=yes
  MASTER=bond0
  SLAVE=yes
  BOOTPROTO=none

  DEVICE=eth1
  USERCTL= no
  ONBOOT=yes
  MASTER=bond0
  SLAVE=yes
  BOOTPROTO=none
3) Created a network script for the bonding device is 
"/etc/sysconfig/network-scripts/ifcfg-bond0"
  DEVICE=bond0
  USERCTL=no
  ONBOOT=yes     NETMASK=255.255.255.0
  GATEWAY=192.168.13.1
  IPADDR=192.168.13.110
4) Reboot the system for the changes to take effect.

After i am rebooted both the server then cluster node becomes simplex 
and Services are started on both the nodes

secondary                               Online, Local, rgmanager

Service Name         Owner (Last)                   State
------------         --------------                --------
Service              secondary                     started

Before Ethernet Channel Bonding cluster services are active in one node 
and other nodes acts as passive node.
But after Ethernet Channel Bonding cluster services are active on both 
the nodes

I don't know what is the problem and is their any configuration is 
required in cluster configuration file and
cman is working only with eth0 interface

Can some one throw light on this peculiar problem
