Installing RAC again? What do you mean by RAC? If it is just the GRID and ASM, then it is OK..
Please remember the following;
A fresh install cannot be done in a pre-created database, single node or RAC-enabled.
Such a thing is only applicable to do an Upgrade. Other than that, rapid install will create its database from scratch using the downloaded CD's.

So you started dbca manually, just to ensure that your environment is okay, able to run a RAC database without a problem, right? But even then, you got some communication problems between RAC services and DB services.. This is so generic. No data for me to comment on this.

Anyways, you have ORA-27101 and you have Database SID ==> null in the autoconfig log (I believe..)
If your DB was okay, up& running properly as a RAC database, then probably you had some config missing in DB or Cluster level. (a config which is needed by EBS for reading the SID of the database) -- this may be a consequence of another missing thing.

You may encounter the same issue after reinstalling GRID and retrying the rapid install.. If that's happens, please send me the whole autoconfig log, your listener services output, your srvctl output, your db name and sid. With all that, I could help you.
