About using a cleaning tape
You can specify the number of cleanings that are allowed for a cleaning tape. This number is reduced with each cleaning. When the number of cleanings is zero, NetBackup stops by using the cleaning tape. Then, use a new cleaning tape or increase the number of cleanings that are allowed for the tape.
Note:
NetBackup does not control the cleaning tapes that library-based cleaning uses.
Cohesity suggests following the recommendations from cleaning tape vendors for the amount of tape usage. If you clean a tape past its recommended life, cleaning delays can occur (due to excessive tape position operations) and drives can be downed.
