Getting following error when doing a delete command. I can not run a crosscheck command since we backup the backups via OS to tape and then delete the file that rman had created. Therefore, only the most current backup is on disk. How do I resolve this error? RMAN> delete noprompt expired backup; 2> delete obsolete; 3> backup as compressed backupset database plus archivelog delete input; 4> exit; ... RMAN-06207: WARNING: 5 objects could not be deleted for DISK channel(s) due RMAN-06208: to mismatched status.

and my reply.
If you use the DELETE command with the optional FORCE keyword, RMAN deletes the specified backups, but ignores any I/O errors, including those that occur when a backup is missing from disk or tape. *If your Oracle Database version is 9iR2 or later, you can use FORCE option. For example: DELETE FORCE NOPROMPT BACKUPSET TAG 'weekly_bkup'; http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/maint003.htm#sthref721
