RMAN does what it wants
I'll keep this brief cuz the details are a mess unless you're here.
To clone a RAC database from one RAC to another, I've been using scripts. The meat of the backup script is:
# Tell RMAN to put this backup in an area outside of the RECOVERY_DEST
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/net/stage.cc.campus/vol/iso_birdscratch/ISISBKUP/%F';
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/net/stage.cc.campus/vol/iso_birdscratch/ISISBKUP/%U';
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/net/stage.cc.campus/vol/iso_birdscratch/ISISBKUP/snapcf_ISIS.f';
