API_BARCODE_RULES entry in vm.conf
The following configuration entry applies to NetBackup servers:
API_BARCODE_RULES
If this entry is specified in vm.conf, barcode rule support for API robots is enabled.
NetBackup barcode rules allow default media mappings to be overridden. Barcode rules are especially useful when multiple generations of the same tape drive use the same type of media.
For example STK 9940A and STK 9940B drives use STK1R media, but write data at different densities. The drive must be configured by using different drive types such as HCART or HCART2. Specify a barcode rule for a series of bar codes to configure some of the media as HCART2. Other STK1R media not in this barcode range are configured as HCART (the default for STK1R). Without this entry, a robot inventory operation configures all media of type STK1R as either HCART or HCART2, depending on how the drive was configured.
