I store archivelog on the separate catalog from catalogs where controlfiles,redologs and datafiles are existing. Please try to take a backup on your database where archivelogs and datafiles are on the same catalog. You'll how it's going on .
Thank you guys, I made a mistake not setting my archive log destination to the preconfigured netapp volume but to the flash recovery area which is on a local disk. I looked at the smo logs and realized the problem at the point where SMO issued the command df to figure out the volumes for the archived log, redo log, etc.
