Is there a script that prevents a tape from being reused? 

Only script i found was the mark tape full, but that doesn´t assure me that the tape won’t get used once the data in it expires.

I have around 12k tapes that i need to prevent reuse and doing it via GUI doens’t seem to be very workable.

Any ideas?


Kind regards,

Have you tried qcommand where you can add a list of bar codes and maxime the number of tapes at once?

qmedia markfull -b <barcode(s)> [-af <argsfile>] [-tf <tokenfile>] [-tk <token>] [-h]


If those tapes have been used a while back, I do not think you would have problems with the statement below (2min rule) and so you could potentially just insert them back and start running the command to a list of tapes.

  • This option marks media full, 2 minutes after the completion of the backup/archive operation. If any jobs are initiated within the 2 minutes, they are allowed to write to the media. If the job was associated with the prior media, new media (such as a new tape) will be used for subsequent jobs. (Applies to all backup/archive types.)

@dude but once the data is expired on that media, it goes back to the scratch pool and i want to avoid that.

What is the retention configuration you are using on the storage policy for that particular tape job? can you change that?

A bit confused as you want to mark the media full and do not want to write data to it anymore, yet there seems to be a retention period that expires.

What i need is to prevent reuse of assigned media and to make sure that no data is written on those tapes. I could do prevent reuse 1 by 1, but i have 12k tapes to do that...

I do not have a written script, I believe qcommand could help or perhaps selecting the media in question and marking as "Prevent Reuse” then moving it to tehe “Overwrite Protect Media Pool”

Overwrite Protect Media

So my only option is to go click  1 by 1 on the 12k tapes… ok thank you anyway

Or you can just select all CRTL + A, Right Click, ALl Tasks, Prevent Reuse. That will work too.

the barcodes are not sequential unfortunately..

@jmiamaral , late to the party (was on holiday), though I’d like to help.

Do you have a list of the barcodes in a text file (so you can use command line options to move them to the protected pool)?

I know we have some scripts to modify retention (so you could mass change jobs), so we just need to figure out what data you have (i.e. a text file of barcodes) to see what options we have.

Let me see if I can get you an answer.  Give me a bit; I’m sure I can find you something!

@jmiamaral , I spoke to the top developers who own these features, and there is currently no option to do this via command line.

I took the liberty of creating a CMR in your name (341770) and assigned it to your main CommCell.

Unfortunately, that means there’s no option (for now) other then what @dude suggested.

@Mike Struening Ok thank you.
