Archiver is unable to archive a redo log because the output device is full or unavailable.
The instance is open.
1. Increase db_recovery_file_dest_size
2. Start full as backup database plus archivelog or start archive log backup than delete them.
3. If you have option delete some archive files from OS level than run crosscheck command from rman
I like to solve this issue using miainly grid control/enterprise manager
