If the host attempts to move a cartridge to a cleaning cartridge's
home location while the cleaning cartridge is being used in a
cleaning operation, the Move Medium command fails, a check
condition is set in the returned status byte and a subsequent
Request Sense returns a Cleaning Cartridge Installed status (SK=5
ASC=30 ASCQ=03). The cleaning cartridge's original location is
not available until either the library determines that the cleaning
cartridge's location is empty (with an Initialize Element Status) or
the library moves the cleaning cartridge to a different storage
element.
When a cleaning cartridge is placed into a drive, the drive loads
the cartridge and initiates the cleaning operation. The library is still
available to service host-initiated commands during the drive
cleaning operation.
If the host attempts to move a cartridge into the drive that is being
cleaned, a check condition is set in the returned status byte and a
subsequent Request Sense returns a Cleaning Cartridge Installed
status (SK=5 ASC=30 ASCQ=03).
Upon completion of the cleaning operation, the drive rewinds and
unloads the cleaning cartridge.
Unsuccessful drive cleaning operations may not rewind
Note:
and unload the cartridge, especially if it is a data
cartridge incorrectly labeled as a cleaning cartridge.
If a drive does not complete the cleaning operation and unload the
cleaning cartridge within five minutes, the library classifies the
cartridge as defective.
The library monitors the drive "HANDLE_OK" flag to determine
when the cleaning cartridge has been unloaded.
