I didn't found at Cluster Administration Documentation (docs.redhat.com) that it's necessarily to start rgmanager separated.
now the Service up and running.

 Service Name                   Owner (Last)                   State
 ------- ----                  
 ----- ------                   -----
 service:webprod                vbox1.example.local            started

Thank you very much Colin.

Maybe I'm missing something but it just looks like the "rgmanager" service isn't started?

Subject:  RHCS simple ip-failover problem

Dear List,

I've received today a evaluation License for
RHEL 6.1[Red Hat Enterprise Linux Server release 6.1 (Santiago)] for learning purposes with the
RHCS.

So I've setup 2 machines vbox1 and
vbox2, with 2 Interfaces (Intranet + 
Hearbeat) and created a cluster.conf with a simple
IP-fail-over Scenario.

Starting the cluster no node takes the IP.

After checking cluster state I'm a little bit confused, it doesn't list the service.

Maybe i understood something wrong from the documentation.

[root@vbox1 cluster]#
clustat  -l
Cluster Status for
vbox @ Sun Nov 27 14:38:00 2011
Member Status: Quorate

 Member Name                             ID   Status
 ------ ----                             ---- ------
 vbox1.example.local                         1
Online, Local
 vbox2.example.local                         2
Online

By testing the rules the system takes the ip-address.
