I'm practicing recovery (this is not an emergency). Did an RMAN backup. (9.2 on Solaris)

Originally:
testdb:/d02/testdb> ls redo*
redo01a.log
redo01b.log
redo02a.log
redo02b.log

I deleted all database files EXCEPT one control_01.ctl file and one redo01a.log
I did an RMAN restore and recovery successfully.
I created control_02.ctl from control_01.ctl
I copied redo01a.log to redo01b.log
I copied redo01a.log to redo02a.log from redo01a.log <-----This was where I went wrong !!

The Problem:
SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-00341: log 2 of thread 1, wrong log # in header
ORA-00312: online log 2 thread 1: '/d02/testdb/redo02a.log'
ORA-00312: online log 2 thread 1: '/d02/testdb/redo02b.log'

testdb:/d02/testdb> oerr ora 341
00341, 00000, "log %s of thread %s, wrong log # %s in header"
// *Cause: The internal information in an online log file does not match the controlfile.
// *Action: Restore correct file or reset logs.

But the OPEN with RESETLOGS fails too:
SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery

So I cant restore redo02a.log and redo02b.log from anywhere or OPEN RESETLOGS because it's not an imcomplete recovery. What to do???
