I need to delete some datasets via JCL in a batch job. In this case, they happen to be on tape. I've tried deleting by setting the DISP parameters to DELETE and also by IDCAMS.

But after the jobs run, I am still able to look up the files using a VOLSER. They seem to be acting like an uncataloged dataset.

I may be missing something here. These file contain data that some would consider sensitive, so we need to delete all traces of these files. We do not want people to be able to reference the data at all.

Any idea?

Until the tape is written over by something, erased, or initalized the data would still be readable.

Ok, I had a feeling that was the case. Is there a way to force one of those scenarios?

Talk with your tape/storage management people. They may have a policy in place about tapes leaving the facility.

And they should have a facility to wipe a tape (apart from a magnet!)

If you have the tape management authority to select a specific volser as output, then write to the tape with a load of rubbish to replace the sensitive data.
