Crosscheck to sync the database dictionary, otherwise you will get error, when you take archive log backup of missing archive log
RMAN> crosscheck archivelog all;
released channel: ORA_DISK_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=513 instance=demo1 devtype=DISK
validation succeeded for archived log
archive log filename=+ORAFLASH001/demo/archivelog/2010_10_08/thread_1_seq_8407.1953.731809149 recid=6562 stamp=731809152
