Apply Cartridge Labels
Cartridge labels reflect the cartridge media and usage. If your cartridges were not 
ordered with labels already applied, you must apply them yourself. You must correctly 
label all cartridges for tape library use.
Valid Labels
LTO cartridge labels have eight characters. The last two characters are the Media ID 
(C1, C2, CU, L1, L2, L3, L4, or L5). CLN or DG are the first characters on the cleaning 
or diagnostic label.

Caution. Possible misread of volume number label: Make sure the edges of the labels do not 
curl. Curling causes the cartridges to stick in the tape drive loader and the robot to misread the 
label.
