[Linux-cluster] RHCS simple ip-failover problem

Sun Nov 27 16:11:53 UTC 2011

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.
