Robotic System and Barcode Scanner

The robotic system identifies and moves the cartridges between the storage slots, tape drives, and the I/E station. The
robotic arm (picker) has picker fingers that enable it to grab tape cartridges and move them into positions along X, Y, and Z
motion coordinates. The robotic system and the barcode scanner work together to identify the locations of resources within
the library.
Each tape cartridge must contain a barcode that the barcode scanner reads during the inventory process. During the inventory
process, the barcode scanner reads the fiducial labels to identify the types of magazines and tape drives that are installed in
the library.
Every tape cartridge must have a unique machine-readable barcode attached to it. Tape cartridges cannot have duplicate
barcode labels. This barcode identifies the cartridge. The library stores the physical location of the tape cartridge in an
inventory database. All library or host requests typically reference the location of the tape cartridges based on this barcode
number. Barcode labels are mandatory and must adhere to specific standards. For more information on barcodes, see

Tape Drive Support

Details about tape drive support include:
• Every library configuration must contain at least one tape drive.
• 5U Library Control Modules can hold a maximum of two tape drives.
• 9U Library Expansion Modules can hold a maximum of four tape drives.

Supported Components
The library supports mixing different tape drive types within the library and within partitions. For information on how to do
this, see Working With
SCSI and SAS tape drives are attached directly to the host. FC tape drives can be directly attached to hosts or to the Storage
Area Network (SAN). FC tape drives can also be attached to FC I/O blades, which manage communication between the hosts
and the drives. For more information on FC I/O blades, see
Tape drives are installed into tape drive slots in the rear of the library. If a tape drive slot is empty, a filler plate covers the
