Redundant ring protocol in CMAN works very fine with >=RHEL6.4 (I only 
use in active mode though).

Is it possible that lotus-5vm8 (from DNS) and lotus-5vm8-ring1 (from 
/etc/hosts) resolves to the same IP ( which could maybe 
confuse cman and make it decide that there is only one ring ?

In my case, to be extra safe, and because I want everything to work 
without network in case of admin interventions/failures (whatever), I 
always put both entries in /etc/hosts, eg: node01 node01.example.com node01_alt node01_alt.example.com
