Another RMAN issue

[NDT]

Hi all, I'm trying to backup all my archived logs file in a test DB using RMAN. I used this command '....archive all ...delete input' . The command ran successfully but when I checked the archive directory everything was deleted except two archived files, anyone knows why this happens?? (based on the seq, the two archived files are in the middle)..please help. Thanks

Can you check whether those that were not deleted were backed up as well? You can run

list backup of archivelog all;
from the RMAN prompt.

They are not on that list, any ideas??
