Drive Cleaning
Drive Cleaning
The library tape drives require periodic cleaning to prevent read and write errors. The library supports two methods of drive cleaning:
■Automatic Cleaning
■Manual Cleaning
Cleaning Cartridges
Note – You must use cleaning cartridges whose media types are compatible with the drive types in the library.
Cleaning cartridges have a limited life span. Refer to your tape drive publications to determine the maximum usage count, or threshold, for each type of cleaning cartridge.
When you enter a cleaning cartridge into the library, the library controller considers the cartridge to be new and sets the usage count to zero. It is therefore important to enter only new cleaning cartridges into the library.
Whenever a cleaning cartridge is used to clean a drive, its usage count is incremented. When a cleaning cartridge’s usage count exceeds its threshold, the cartridge must be replaced.
You can use the SL Console to display the status of a cleaning cartridge at any time. The following statuses are possible:

Ejecting Expired Cleaning Cartridges
You must use care when ejecting expired cleaning cartridges from the library. If you move an expired cleaning cartridge to a CAP and open the CAP, you must remove the cartridge. If you close the CAP without removing the cleaning cartridge first, the HandBot will
Automatic Cleaning
When auto clean is enabled, the library controller automatically initiates a cleaning operation whenever a drive requires cleaning. The HandBot retrieves an appropriate cleaning cartridge (based on drive type) from the reserved cells, mounts the cartridge onto the drive, and returns the cartridge to its assigned storage cell after cleaning is complete.
