Barcodes

◆
Volumes in an API robot have a real or a logical barcode. This volume identifier is
used as the Media Manager media ID. This volume identifier is the volume serial
number in ACS, LMF, TLH, and TLM robots.
For RSM robots, the last six characters of the media name are used as the volume
identifier. If these characters contain spaces, only the characters back to the first space
are used.
◆
For API robots, the barcode for a volume must be identical to the media ID.
You can match barcodes to media IDs by getting custom labels in the same series as
your media IDs. For example, to match a set of media IDs from AA0000 to ZZ9999, get
barcode labels in that series.
◆
When a robotic library can contain more than one media type, a good strategy for
assigning barcodes is to assign specific characters in the barcode to different media
types using media ID generation rules (see “Media ID Generation Rules” on
page 289). Also recommended is to use barcodes to differentiate between data tapes
and cleaning tapes, or to differentiate between volume pools.
Barcode Rules
A barcode rule specifies criteria for assigning attributes to new robotic volumes. These
attributes are assigned by Media Manager using the following:
◆
The barcode attached to the volume that is read by the robotic library.
◆
Any rules that are defined.
In Media Manager, you choose whether to use barcode rules when you set up the robot
inventory update operation. The barcode rules that are actually used by Media Manager
are the rules that are stored on the volume database host that is the target of the robot
inventory update operation.
Example Barcode Rules
The following table shows some sample barcode rules. Rules are sorted first according to
the number of characters in the barcode tag and then by the order you add them. Two
exceptions are the <NONE> and <DEFAULT> rules, which are always at the end of the
list.
