Backup files not found in ASM

I have an Oracle database 11gr2 and I have installed Oracle Grid on Oracle Linux 5.9. I have two disk groups. /etc/init.d/oracleasm listdisks : flash_recovery_area DATA The first disk group is mounted on /u01 and the second is mounted on /flash_recovery_area. The value of fra parameters are: db_recovery_file_dest = /+flash_recovery_area db_recovery_file_dest_size = 30G When I want to connect to rman and get backup from current database, I can but I can not find anything in /flash_recovery_area destination. Can any one help me?
