LTO Autoloader Barcode Reader
Volume Identifier Formats
!
The volume identifier only uses ASCII characters A through Z (41h-5Ah), 0 through 9
(30h-39h), and the combinations of “CLN” and “DG {space} ” as described below.
!
The prefix “CLNvnnL1”is reserved for cleaning cartridges. The “v” field is an
alphanumeric field to identify a drive unique cleaning cartridge. The “nn” alphanumeric
field is used to track individual cleaning cartridge activity (for example, usage and life).
When the drive requires cleaning, it will request loading of the unique type cleaner
cartridge.
!
Diagnostic/Service cartridges use the prefix “DG{ space} vnnL1”. The “v” field is an
alphanumeric field to identify a drive-unique diagnostic cartridge, if required. The “nn”
alphanumeric field identifies a specific diagnostic cartridge volume.
!
The volume identifier field consists of six left-justified alphanumeric characters as
specified in SCSI-3 Medium Changer Commands (SMC) ANSI NCITS 314-199X.
!
The media identifier characters “Lg” are controlled characters. The “L” designates the
LTO Ultrium type of cartridge. The next character “g” (alphanumeric) designates the
generation of the LTO Ultrium cartridge.
Reading area
Due to mechanical tolerances the barcode reader will read in a defined area with a height of 5,15
mm (see figure below). This area must contain barcode information only and should not contain
any character information.
