How to create 2nd set of online redo logs for node 2 RAC

I am trying to setup RAC on a two node cluster. I was able to mount and start the database on both nodes alternately. I am about to try and bring up the two instances on the two node RAC, however I think a am missing something.

Can anybody tell me how to create the 2nd set of on-line redo logs (thread 2) for my second node rac.

it would look something like this

alter database add logfile thread 2
group 3 ('d:\oracle\oradata\redoXXX.dbf') size 254m reuse, group 4 ('d:\oracle\oradata\redoXXX.dbf') size 254m reuse;

alter database enable public thread 2;

...notice that thread 2 is the key here enabling the logs for the 2nd instance
