There are two special barcode rules you can add for just this purpose.
(from page 563 of the 6.5 NetBackup admin guide I for unix)
The following are special barcode rules that can match special characters in the barcode tags:
- NONE. Matches when rules are used and the volume has an unreadable barcode or the robot does not support barcodes.
- DEFAULT. For volumes with barcodes, this tag matches when none of the other barcode tags match. However, the following must be compatible: the media type in the DEFAULT rule and the media type on the Media Settings tab
You should always add the DEFAULT tag as the last one in the list, after the CLN tags. With the DEFAULT tag you can have any new media added directly into the Scratch pool.
We use the NONE tag just above the DEFAULT tag to take media with non-readable barcodes and put them into the NONE pool to be ejected and re-labled later.
I hope this helps,
Luc.
