Hi Neil! Roger stated that he is pretty sure that when he deletes a volume on physical tape, the volume becomes pending. In my case it's turning into scratch immediately and thus being relabeled immediately. I don't understand why it should work differently... Kind regards, Eric van Loon Air France/KLM Storage Engineering

By typing the words DISCARDDATA=YES, I guess you are explicitly consenting to never being able to access the data again. You might have a way back if by chance a physical tape hasn't been re-used by the time you realise your mistake, but with virtual tape the data erasure is immediate when the volume is relabelled. I suppose my advice would be to only use DISCARDDATA=YES in the event that all remaining data on the volume has already proven (through MOVE DATA operations, or whatever) to be unreadable, and you don't have the option to recover it from a copy pool. In this case, a pending reuse delay wouldn't help make the data any more readable. I realise this doesn't address your concerns around accidental deletion of a volume, but I believe there's a saying about great responsibility accompanying great power.
