Accidentally created local df in RAC

I've got a potential resume-faxing situation in dealing with a 20+ TB db.  This 
is on a 6-node RAC, Oracle 10.2.0.4, RHEL 4.x, ASM, OMF.

I added a datafile to a tablespace on node1 and unfortunately forgot the plus 
sign in front of the diskgroup.  We use OMF so what happened is instead of a 
datafile getting added to ASM under <diskgroup>/<db>... it created one on node1 
under $ORACLE_HOME/dbs.  Of course the other 5 nodes started complaining about 
ORA-01157 errors.  I saw this right away and quickly offlined the datafile.  
Now the datafile has an ONLINE_STATUS of "RECOVER".

Unfortunately the database is in noarchivelog mode and also critical production 
(odd combo, I know), so I'm paranoid on trying anything further.  My thought is 
to use DBMS_FILE_TRANSFER to put the datafile in ASM, then do a rename and 
bring it online.  Is that the best method?  I'm pretty sure nothing got written 
to the datafile as DBA_EXTENTS shows no extents in that FILE_ID.

Thoughts?
