Monitoring Usage

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.
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).
Each time a cleaning cartridge is removed from a drive by the
robotics, the "use count" for that cleaning cartridge is incremented
by one. When the "use count" reaches the maximum allowable
number of 20, (in automatic cleaning mode) the cleaning cartridge
is moved to the load port.
A cleaning cartridge that is defective will have its number of uses
set to 20, and the library will move it to the load port.
When a cleaning cartridge has been exported from the library, all
record of that cleaning cartridge is deleted.
