Cleaning cartridge (HP-configured or Universal)
When a valid cleaning cartridge (one that has not expired) is loaded, behavior depends on the Clean Protect bit of the Set Drive Configuration command.
Clean Protect = 1 f the Clean Protect bit is set to 1, the drive will not thread the tape or clean the drive until an ACI Load command with the Clean bit set to 1 is sent to the drive. If the Load command is sent without the Clean bit set the drive will return a CHECK CONDITION. Also, if the “cleaning cartridge” is not in fact a cleaning cartridge, the Load command with the Clean bit set to 1 will produce a CHECK
CONDITION.
Clean Protect = 0 If the Clean Protect bit in the Set Drive Configuration command is set to 0, the drive will thread the tape and clean the drive when a cleaning tape is loaded.
When the cleaning cartridge is seated in the drive, the ‘cartridge type’ field in the Get Drive Status RDATA will be set to 06h (cleaning).
While the drive is cleaning, the Cleaning bit in the Get Drive Status RDATA will be set to 1 and the Tape Activity field will be set to Ah (cleaning).
When cleaning has finished, if
Tape Activity = ‘Idle’. The cartridge can now be unloaded from the drive.
Expired cleaning cartridge (HP-configured or Universal)
If an expired cleaning cartridge is loaded into the drive, the cartridge will be placed in the ready eject position with the Cartridge Present, Write Protect, Ready Eject, Ready Load, Media Error, TapeAlert, and Clean Expired bits set to 1, Cartridge Type = ‘Cleaning’, and Tape Activity = ‘Idle’. TapeAlert flag 22h will be set.
