[ovirt-users] [Centos7.1] [Ovirt 3.5.2] hosted engine, is there a way to resume deploy

Hi, I tried to deploy ovirt hosted engine 3.5.2 on a Centos7.1 I messed up things with datacenter naming, I used something else than Default, and the result was that, after the DB welcome message between the engine and the hypervisor, there was in error (I didn't catch it I was using screen command over ssh without log :-( ), and the last steps were not done, so I ended up an engine up but without the hypervisor being registred. Is there a way to force the registration again, or will I have to deploy from the beginning and reinstall the VM engine? thanks.
