Media Movement from the Drive
3
Whether a cleaning operation is successful or unsuccessful, the
library increments the cleaning cartridge’s “use count” and
attempts to move the cleaning cartridge back to its home location.
If an export or movement operation cannot be completed due to
unrecoverable errors, the library attempts to return the cleaning
cartridge to its original storage element to clear the transport
element. If an unrecoverable error occurs during the movement of
a cleaning cartridge that prevents a subsequent host-initiated
command from completing, a check condition is set in the returned
status byte and a subsequent Request Sense returns the
appropriate error code.
Unloading Cleaning Cartridges
3
When each cleaning operation is completed, the library moves all
cleaning cartridges that have been marked as “used up” to the load
port.
