Barcode rules settings
The following table describes the settings you can configure for barcode rules. NetBackup uses these rules to assign barcodes to new media.
Table: Barcode rule settings
Barcode rule setting | Description |
|---|---|
Barcode tag | A unique string of barcode characters that identifies the type of media. For example, use DLT as the barcode tag for a barcode rule if the following is true:
Similarly, if you use CLND for DLT cleaning media, use CLND as the barcode tag for the rule for DLT cleaning media. The barcode tag can have from 1 to 16 characters but cannot contain spaces. The following are the special barcode rules that can match special characters in the barcode tags:
You cannot change the barcode tag of a barcode rule. Instead, first delete the old rule, then add a rule with a new barcode tag. Use the Media Settings tab to set up the criteria for a robot update. |
Description | A description of the barcode rule. Enter from 1 to 25 characters. |
Maximum mounts | The maximum number of mounts (or cleanings) that are allowed for the volume. For data volumes, a value of zero means the volume can be mounted an unlimited number of times. For cleaning tapes, zero means that the cleaning tape is not used. Veritas recommends that you use barcodes for the cleaning media that cannot be confused with barcodes for data media. Doing so can avoid a value of 0 for cleaning tapes. |
Media type option | The media type to assign to the media. The media type that is specified on the Media Settings tab always overrides the media type of the barcode rule. If you specify a value other than DEFAULT on the Media Settings tab, the barcode rule media type must be the same as the media or be DEFAULT. If not, the barcode rule does not match the media (except for cleaning media). Note: When a media type is selected, the maximum mounts value may revert to the default value for the specified media type. For example, it may revert to 0 for unlimited when you select a non-cleaning media type. |
Volume pool | The volume pool for the new media. The actions depend on whether you use barcode rules to assign media attributes. Select from the following:
