Note: The drive automatically ejects an expired cleaning cartridge without running the cleaning process.
Replace the expired cleaning cartridge with a new cleaning cartridge and insert it into the drive.
The IBM cleaning cartridges are valid for 50 uses. The cartridge's LTO-CM chip tracks the number of
times that the cartridge is used.
Important: After 50 uses, the cleaning cartridge expires. It is no longer usable, and must be replaced
Cartridge memory chip (LTO-CM)
All generations of the IBM LTO Ultrium Data Cartridges include a Linear Tape-Open Cartridge Memory
(LTO-CM) chip (
▌1▐
in Figure 11 on page 37) that contains information about the cartridge and the tape
(such as the name of the manufacturer that created the tape), and also statistical information about how
to use the cartridges. The LTO-CM enhances the efficiency of the cartridge. For example, the LTO-CM
stores the end-of-data location which, when the next time this cartridge is inserted and the Write
command is issued, enables the drive to quickly locate the recording area and begin recording. The
LTO-CM also aids in determining the reliability of the cartridge by storing data about its age, how many
times it was loaded, and how many errors it accumulated. Whenever you unload a tape cartridge the
tape drive writes any pertinent information to the cartridge memory.
The storage capacity of the LTO Generation 6, 7, and 8 LTO-CM is 16320 bytes. The storage capacity of
the LTO Generation 4 and 5 LTO-CM is 8160 bytes. LTO Generations 1, 2, and 3 have an LTO-CM
capacity of 4096 bytes.
Bar code label
A bar code label contains:
v
A volume serial number (VOLSER) that is human-readable.
v A bar code that the library can read.
Note: The LTO Ultrium 8 tape drives do not require bar code labels, but you might choose to use labels
for tape cartridge identification purposes.

When read by a library 's bar code reader, the bar code identifies the cartridge 's VOLSER to the library.
The bar code also tells the library whether the cartridge is a data cartridge or cleaning cartridge. In
addition, the bar code includes the two-character media-type identifier
Lx
, where
x
equals 1, 2, 3, 4, 5, 6 7
or 8.
L
identifies the cartridge as an LTO cartridge and the number represents the generation of cartridge
for that cartridge type. Figure 13 on page 43 shows a sample bar code label for the LTO Ultrium Tape
Cartridge.
