So many variables, but here is a generalization:

--- If you init.ora is set as such ---
DB_CREATE_ONLINE_LOG_DEST_1 = '+dgroup1'
DB_CREATE_ONLINE_LOG_DEST_2 = '+dgroup2'

--- you can then ---
ALTER DATABASE ADD LOGFILE;

With VCS the filesystem is created just like a mount point (at least that is the way we have it configured here)... so to create a new redo log it is the same as if we were using local file systems...

ALTER DATABASE ADD LOGFILE GROUP 2 ('/oracle_prd/oradata/my_db/log2.ora') SIZE 50M;
