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.
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.
Non-HP Ultrium 1 cleaning cartridge
If a non-HP Ultrium 1 cleaning cartridge is loaded into the drive, the cartridge will not be
recognized as a supported cartridge. The cartridge will be placed in the ready eject position with
the Cartridge Present, Write Protect, Ready Eject, Ready Load, Media Error, and TapeAlert bits set to
1, Cartridge Type = ‘Unknown’, and Tape Activity = ‘Idle’. TapeAlert flag 17h will be set.
Unreadable data cartridge
If a data cartridge is loaded that cannot be read, the cartridge will be placed at the ready-to-eject
position with the Cartridge Present, Write Protect, Ready Eject, Ready Load, Media Error, and
TapeAlert bits set to 1, Cartridge Type = ‘Unknown’, and Tape Activity = ‘Idle’. TapeAlert flag 05h
will be set.
Ultrium 5 and later data cartridges
If an Ultrium 5 or later data cartridge is loaded into the drive, the drive will recognize the cartridge
as a non-supported cartridge. The cartridge will be placed at the ready-to-eject position with the
Cartridge Present, Write Protect, Ready Eject, Ready Load, Media Error, and TapeAlert bits set to 1,
Cartridge Type = ‘Unknown’, and Tape Activity = ‘Idle’. TapeAlert flag 0Ch will be set.
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 Auto-Eject is disabled, the cartridge will be in
the ready eject position with the Cartridge Present, Write Protect, Ready Eject,
and Ready Load bits set to 1, Cartridge Type = ‘Cleaning’, and
Tape Activity = ‘Idle’. The cartridge can now be unloaded from the drive.
