Appendix C Automatic Drive Cleaning
Cleaning Cartridges
Element Status

Information
104
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.
The presence of cleaning cartridges results in the reporting of
additional status information in response to host-initiated Read
Element Status commands. This additional information is only
present in automatic cleaning mode and is suppressed in host-
initiated cleaning mode. The additional information may consist of
the Except bit being set and the Additional Sense Code and
Additional Sense Code Qualifier values being filled-in as well as
possible changes to the Access bit (described below).
A storage element that contains a cleaning cartridge that is not
used up has the Access bit set to 1, the Except bit set to 1, and the
status set to Cleaning Cartridge Installed (ASC=30 ASCQ=03).
A storage element that contains a cleaning cartridge that is used up
has the Access bit set to 1, the Except bit set to 1, and the status set
to Operator Medium Removal Request (ASC=5A ASCQ=01).
A storage element that is empty but is the home location for a
cleaning cartridge that is currently being used in a cleaning
operation has the Access bit set to 0, the Except bit set to 1 and the
status set to Cleaning Cartridge Installed (ASC=30 ASCQ=03).
A data transfer element that is currently being cleaned as part of an
automatic cleaning operation has the Access bit set to 0, the Except
bit set to 1, and the status set to Cleaning Cartridge Installed
(ASC=30 ASCQ=03).
