Cleaning cartridge

With each library, a specially labeled IBM LTO Ultrium Cleaning Cartridge is supplied to clean the drive
head. The drive itself determines when a head must be cleaned. It alerts you by lighting the "Clean
Drive" (amber LED) above the library Operator Control Panel. To clean the head manually, insert a
cleaning cartridge into the tape load compartment (see "Inserting the cleaning cartridge" on page 79). The
drive completes the cleaning automatically. When the cleaning is finished, the drive ejects the cartridge,
and the library turns off the Clean Drive LED. Some libraries have an Auto Clean function, which when
enabled, prompts the library to retrieve the cleaning cartridge that is contained in the library, inserts it in
the drive that needs cleaning, cleans the drive, then returns the cleaning cartridge to its home slot.
Note: The drive automatically ejects an expired cleaning cartridge.
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.

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 143 on page 163), 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
the cartridge 's use. 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 a tape cartridge is unloaded, the
tape drive writes any pertinent information to the cartridge memory.
The storage capacity of the LTO Generations 6, 7, M8, 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: LTO drives do not require cartridges to have bar code labels, but you might choose to use labels
for tape cartridge identification purposes. Specific library types or models might require cartridges to
have bar code labels.
