Bacula Erasing Tapes And Automatic Labeling Script

I have been using Bacula since 2005.

About a year ago, I obtained about 200 HP Lto4 tapes from i dismantled It project. They were no longer used at work until now.

In order for me to use them again, I needed to erase the tapes without disabling the bacula storage daemon and needed to add i new label to them.

Based upon an existing script on the internet “https://dan.langille.org/2011/05/27/bacula-removing-labels-then-labeling-tapes/”, I wrote this script.

With this, I can insert new tapes, add an external barcode label, put the mazagine in the tape library, and in 30 minutes, have new volumes.

do

mt -f ${DRIVE} rewind

mt -f ${DRIVE} rewind

# now label that slot

bconsole END_OF_DATA
label barcodes pool=$POOL storage=$STORAGE slot=${slot}

yes
umount storage=$STORAGE
quit
END_OF_DATA
done

To run this script, I issue this command:

time sudo sh ~/bin/EraseTapeLabels pass11 sa0 1 200 poolname storagename

where

time – tells me how long the rest of the command takes
sudo – I am running this as non-root; sudo makes me root
pass11 – my tape changer
sa0 – the tape drive
1 – Initial Slot
200 – Slot End
Poolname – Name of the pool to insert the new Volumes
Storagename – Name of the Storage to label the new Volumes
