Cleaning properties for devices

Cleaning properties for devices provide statistics on totals and errors since the last cleaning. The documentation included with your device should list the acceptable limits for hard and soft errors; if not, check with the hardware manufacturer.

For robotic library drives, the statistics on the Cleaning tab are automatically updated when a cleaning job successfully completes.

If you want to maintain accurate cleaning statistics for your stand-alone drives, you can reset the cleaning statistics after the drive has been manually cleaned.

See Creating a cleaning job.
