Tape Cleaning and Certification

You can use the TMSCLNOA utility to indicate which scratch tapes require cleaning based on your criteria. This criteria is passed as parameter input to TMSCLNOA, and can be a number of days since last cleaning, number of uses, number of read/write errors, or any combination of the three. Once the criteria is met, the next time the volume is listed on the scratch list a "clean" indicator is posted. The tape should then be cleaned before it is used as a scratch. When a tape marked for cleaning is used again for output, the fields associated with clean criteria in the TMC record are automatically reset.
