Use media ID generation rules to override the default media ID naming method NetBackup uses. The default method uses the last six characters of the bar code the robot provides to generate the media ID.
|
Note: |
To use media ID generation rules, the robot must support bar codes and the robot cannot be an API robot. Media ID generation rules are saved in the Media Manager configuration file (vm.conf). |
For example, two eight-character bar codes are S00006L1 and 000006L1. Without any media ID generation rules NetBackup uses the last six characters of the bar code to generate media IDs. In this example, the same media ID for the two bar codes is created (0006L1).
Use a rule to control how NetBackup creates media IDs by specifying which characters of a bar code are used in the media ID. Or, specify that alphanumeric characters are to be inserted into the ID.
Define multiple rules to accommodate the robots and the bar code lengths. Define rules to specific robots and for each bar code format that has different numbers or characters in the bar code. Multiple rules allow flexibility for the robots that support multiple media types.
