[Pacemaker] cman heartbeat / interconnect configuration

[Dvorak Andreas]

Dear all,

after a little break I am coming back to my problem to configure heartbeat / interconnect with cman.
Meanwhile I know that cman is the recommended stack on RHEL6.
I have a pacemaker cluster with cman that is working, but now a would like to configure special interfaces for the direct node communication (heartbeat / interconnect /keep alive).

Unfortunately I do not understand how configure the interfaces. Can you please give me an advice?
Currently the cluster uses
corosync-cfgtool -s
Printing ring status.
Local node ID 2
RING ID 0
                id            = 10.15.28.27
                status   = ring 0 active with no faults

bond0     Link encap:Ethernet  HWaddr C8:1F:66:D1:8B:23
          inet addr:10.15.28.27  Bcast:10.15.255.255  Mask:255.255.0.0

The interfaces to configure are
em4       Link encap:Ethernet  HWaddr C8:1F:66:D1:8B:24
          inet addr:192.168.2.27  Bcast:192.168.2.255  Mask:255.255.255.0
and
p6p4      Link encap:Ethernet  HWaddr 00:0A:F7:2F:A7:6F
          inet addr:192.168.3.27  Bcast:192.168.3.255  Mask:255.255.255.0

my current configuration
cat /etc/cluster/cluster.conf
<cluster config_version="12" name="mysql-int-prod">
  <fence_daemon/>
  <clusternodes>
    <clusternode name="sv2828" nodeid="1">
      <fence>
        <method name="pcmk-redirect">
          <device name="pcmk" port="sv2828"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="sv2827" nodeid="2">
      <fence>
        <method name="pcmk-redirect">
          <device name="pcmk" port="sv2827"/>
        </method>
      </fence>
    </clusternode>
  </clusternodes>
  <cman/>
  <fencedevices>
    <fencedevice agent="fence_pcmk" name="pcmk"/>
  </fencedevices>
  <rm>
    <failoverdomains/>
    <resources/>
  </rm>
</cluster>

Best regards
