Re-using OLd tapes on Netbackup

If you do not need the data on the tapes - then yes you can reuse them.  As you say you used them for testing.

If the images on the tape have NOT expired yet - and you don't want to keep them you can expire all the images on the tape.

You don't mention if you are using the same master server now going into prod as you did for your test - so that all depends.
   if you are using a new master - then that master does not know anything is on those tapes and they will appear as scratch.
  if you are using the same master and just want to start fresh
 (where $1 is the Tape ID)

/usr/openv/netbackup/bin/admincmd/bpmedialist -m $1

/usr/openv/netbackup/bin/admincmd/bpexpdate -m $1 -d 0

/usr/openv/netbackup/bin/admincmd/bpmedialist -m $1

I have a script that does the above commands.
the first command looks up the tape and shows me info

id rl images allocated last updated density kbytes restores

vimages expiration last read <------- STATUS ------->

(will show if it is frozen - and it shows you when it should expire

the second command will ask if you want to expire

the third command is the same as the first - and if the second command worked the last one will say it cannot find it (because all the images on the tape have been expired)

you can script this to do more then one - (I never have had to do more then one at a time)


Once the tapes are not longer assigned you can put them into the scratch pool.

 

This how I reuse tapes that have a different barcodelabels than when first used. The second command puts the tape into the Netbackup volume pool. Steps 3 &4 are done from the admin GUI.

THank you all I appreciate it.  

If you're using barcodes, those barcodes may be read differently by different tape libraries.  I would also urge you to re-label the tapes so you don't get any inconsistencies between the logical media ID of the tape (the one which NetBackup knows about in the volume database), as compared to the media ID written to the tape's header block.  If those two pieces of information don't match, you'll wind up with a frozen tape.

A re-label operation is a destructive action, and data on a tape would be lost.

remember if you're using barcodes, I believe used tapes  are still keeping old barcode on their header, best way is : reformat the tapes, if not when you restore the files from tape, you'll get problem
