Media ID generation options
NetBackup uses rules to generate the IDs for media in robots. The default rule uses the last six characters of the barcode label from the tape.
You can configure media ID generation rules to override the default rule. Control how NetBackup creates media IDs by defining the rules that specify which characters of a barcode label to use for the media ID.
The following subsections describe the media ID generation rule options.
The following list describes the media ID generation rule options:
The is the number of characters in the barcode for tapes in the robot.
You cannot change the barcode length of a rule. Rather, first delete the rule and then add a new rule.
Media ID generation rule
A consists of a maximum of six colon-separate fields. Numbers define the positions of the characters in the barcode that are to be extracted. For example, the number 2 in a field extracts the second character (from the left) of the barcode. You can specify numbers in any order.
To insert a specific character in a generated media idea, precede the character by a pound sign (#). Any alphanumeric characters that are specified must be valid for a media ID.
Use rules to create media IDs of many formats. However, it may be difficult to manage media if the label on the media and the generated media ID are different.
The table shows some examples of rules and the resulting media IDs.
