Rman is backing up the wrong archive-directory

Question

On a database-server we have two archive-destinations: oraarch01 that must be used for rman and oraarch02 that is used for other purposes. When I start a archivelog-backup with rman, it is using oraarch02 but it should use oraarch01.
Some more information:
log_archive_dest_1=location="/data/oraarch01/DB_P", valid_for=(ONLINE_LOGFILE,ALL_ROLES)
log_archive_dest_2=LOCATION=/data/oraarch02/DB_P OPTIONAL REOPEN=5
Database-version is 10.2.0.4
Rman-scriipt:
run {
allocate channel d1 type disk;
backup archivelog all not backed up 1 times format '/data/backup/rmn_%d_%U.bus' delete input;
delete noprompt archivelog all backed up 1 times to device type disk;
release channel d1;
How can I tell rman to stop backing up the wrong directory?
Thanks.

Answer 1

You could perform the backup like the following:
backup archivelog like '/data/oraarch01/DB_P%'
not backed up 1 times format '/data/backup/rmn_%d_%U.bus' delete input;
