Barcode Advantages
VERITAS suggests that you use media with barcodes in robots that can read barcodes.
Barcodes offer the following advantages:
◆
Automatic media ID assignment.
When you add new media to a robot, Media Manager is able to assign media IDs
according to the criteria that you specify.
◆
More accurate tracking of volume location.
A Robot Inventory Update Volume Configuration operation can determine which
volumes are in a robot.
◆
Increased performance.
Media Manager functions well whether or not barcodes are used. However, not using
barcodes can adversely affect performance for some robots.
A robot that reads barcodes will perform a scan each time it moves a tape. This is
normal and is done in order to store the correct barcode in memory or to verify a
previously saved barcode. However, if a barcode is missing, the robot will retry the
scan multiple times, degrading performance.
Barcode Best Practices
When selecting barcodes for your volumes consider the following important points:
◆
Barcodes appear on labels that you attach to the outside of tape volumes.
Barcodes are not generally used on optical disks and Media Manager does not
support barcodes for optical disk libraries (ODL robots).
◆
The maximum barcode lengths that are supported by Media Manager depend on the
type of robot. See the Barcode Support attribute of the tables listed in “Robot
Attributes” on page 253.
◆
When you purchase barcode labels for use with Media Manager, always follow the
robotic library vendor’s recommendations. Ensure that the barcodes have the correct
number of characters.
◆
Barcodes can represent any combination of alpha and numeric characters, but
different robots support different lengths of barcodes. See the robot vendor’s
documentation to determine the requirements for a specific robot type.
◆
Use barcodes without spaces (leading spaces, trailing spaces, or spaces between any
characters). Otherwise, the robot or Media Manager can have difficulty interpreting
them.
