Test RMAN consistent "as copy" backup outside of ASM (RAC)

Question

Hi!
We have create RMAN consistent backup in our RAC (ASM with FRA) environement.
Backup steps looks like:
alter system set cluster_database=false scope=spfile sid='HAC4';
srvctl stop database -d HACThen we start RMAN backup script like (database is shut downed before):
run {
startup mount;
allocate channel t1 type disk format '/u01/rman_backup/HAC/cold_backup/HAC_%U';
allocate channel t2 type disk format '/u01/rman_backup/HAC/cold_backup/HAC_%U';
SET CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/u01/rman_backup/HAC/cold_backup/HAC_%F_ctl';
backup as copy database include current controlfile;
}After backup we perform:
alter system set cluster_database=true scope=spfile sid='HAC4';
shutdown immediate;and later
srvctl start database -d HACBackup files from this backup are placed on local disk area accessed by node4, where HAC4 SID is on.
We transfer those backup files to tape on some schedule basis...
Now we want to test this backup.
Scenario:
Because we have consistent backup we think that we can perform restore from it (from that disk files) and from it ONLY!
Our problem is that all the time restore is using ASM files, so we are not sure is our backup valid.
So, how to prevent RMAN restore/recover process from using any ASM file - just to use our consistent backup data?
Please some script example for that....
Our config:
Oracle 10gR2.0.4 PS3 (CRS, ASM, database)
Linux Rhel 5.3 IA64 on "raw devices" (not raw disks)

We'll...look this restore for our "as copy" consitent backup. Assume that ${BKUP_DEST} is env variable in bash script which points to same place where backup was done. Here is restore part:
run {
startup force nomount;
RESTORE CONTROLFILE from '${BKUP_DEST}/HAC_20090916T152408_u5kpd8le_1_1_post_ctl';
alter database mount;
sql "alter session set NLS_DATE_LANGUAGE=American";
allocate channel t1 type disk format  '${BKUP_DEST}/HAC_%U';
allocate channel t2 type disk format  '${BKUP_DEST}/HAC_%U';
restore database FROM TAG='TAG20090916T152532' ;
release channel t1;
release channel t2;
}where
TAG='TAG20090916T152532'is tag that was done in backup. This is done from "ac copy" backup. But when we run:
run {
allocate channel t1 type disk format  '${BKUP_DEST}/HAC_%U';
allocate channel t2 type disk format  '${BKUP_DEST}/HAC_%U';
recover database FROM TAG='TAG20090916T152532' ;
release channel t1;
release channel t2;
}RMAN is using archive logs from ASM....and we want to use only files from "as copy" backup-remember we test "as copy" consistent backup.
If we do not run "recover" part then we cannot open database!?
(i.e. alter database open resetlogs).
Hope now is all more clear..

P.S.
Either our backup script is not OK or restore/recover script is bad....
Unfortunatelly we do not know what?
