Storage and 
Tracking
3
Each cleaning cartridge is tracked from the time that it is loaded 
into the library. When a cleaning cartridge is unloaded from the 
library, the library no longer retains information concerning that 
cleaning cartridge (bar code). If a new cleaning cartridge with the 
identical bar code is then imported into the library, it is considered 
a different cleaning cartridge for all tracking purposes.
Each cleaning cartridge must have a unique bar code. If a cleaning 
cartridge with a duplicate bar code label is imported, the original 
cleaning cartridge is moved to the load port for removal from the 
library. 
After a cleaning cartridge is used twenty times it is moved to the 
load port for removal from the library. 
The library adjusts for cleaning cartridges that are manually 
moved within the library while the library is off-line. When an 
inventory is performed (after power-up or a transition from off-
line to on-line), all cartridges are scanned and identified. Each 
cleaning cartridge is checked for a previous record of location and 
use. Cartridges that remain in previous locations retain their 
previous usage information. 
If previous records do not show a cleaning cartridge with the same 
bar code at a given location, the library checks if a cleaning 
cartridge with the same bar code label was previously located at 
another location (and is not currently at that other location). If so, 
the library assumes that it is the same cleaning cartridge that was 
manually moved and retains all cleaning cartridge information. If 
the library cannot locate a previous record for the cleaning 
cartridge, it assumes the cleaning cartridge is new and creates a 
new record for it.
Monitoring 
Usage
3
The library maintains a usage history for each cleaning cartridge 
within the library. The usage history is a count of the number of 
times the cleaning cartridge was used to clean a drive.
When a cleaning cartridge has been identified and imported into 
the library, the usage history for that cleaning cartridge is 
initialized and set to zero (0).
