Failure of Duplicate Db command 11g R2

Question

I have a RAC production(prod) database (11G R2) and created Auxiliary(cscp) database on different server and both have same Solaris 10 platforms. I cannot clone the database using “UNTIL TIME”. I do followings but get error. I would appreciate your help. I am running command from Auxiliary. Should I run RMAN from Prod server?
In Aux Server:
1-     Moved password file
2-     Created init.ora and has following value
DB_NAME='cscp'
3-     startup nomount pfile='/apps/oracle/ora112/dbs/init.ora';
in prod Server:
1-     connect target sys/pw@prod
2-     connect auxiliary sys/pw@cscp;
3-     connect catalog rman/pw@prod;
4-     RUN {
SET NEWNAME FOR DATABASE TO "/apps/oracle/ora112/oradata/%U";
DUPLICATE TARGET DATABASE TO CSCP pfile=/apps/oracle/ora112/dbs/init.ora
SPFILE
NOFILENAMECHECK
UNTIL TIME "to_date('08-09-2010 13:03:14','dd-mm-yyyy hh24:mi:ss')"

GROUP 1 ('/apps/oracle/ora112/redo01a.log') SIZE 50M REUSE,
GROUP 2 ('/apps/oracle/ora112/redo02a.log') SIZE 50M REUSE;
Here is the output:

Hi Maxym,
I used following command and to verify backup files then copy them to other server. I get error. Do you have any suggestions what I get Controllfile is not found?
RMAN> restore database preview until time "to_date('01-10-2010 22:26:30','dd-mm-yyyy hh24:mi:ss')";
When I run Duplicate database command, there was following error generated by the RMAN:
executing command: SET NEWNAME
Starting Duplicate Db at 04-OCT-10
RMAN-00571: ===========================================================

RMAN-05575: CONTROLFILE backup created before to_date('01-10-2010 22:26:30','dd-mm-yyyy hh24:mi:ss') not found in /mnt
After that, I run following command and copied the control file to other server and run duplicate command but still I get same error from rman.
RMAN> restore controlfile preview until time "to_date('01-10-2010 22:26:30','dd-mm-yyyy hh24:mi:ss')";
