My experience of DELETE VOLUME going back to ADSM 3.1 is that it will 
immediately make the library volume (physical or virtual) scratch with no 
pending reuse delay.

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.
