To clean a drive in a tape library using DPM, you specify which tape to use for cleaning, and then start the cleaning job. If the bar code on a tape starts with "CLN" (for example, bar code CLN0000812), DPM identifies the tape as a cleaning tape after a fast inventory.
However, if the cleaning tape does not have a bar code or the bar code does not start with "CLN", you must mark the tape as a cleaning tape and then run a detailed inventory. If you do not mark the tape as a cleaning tape before you run a detailed inventory, a cleaning job will start when DPM mounts this tape during the detailed inventory.
Follow the guidelines from the manufacturer of your tape device for cleaning frequency.
