Exactly.

I can probably dig up those commands, yes. :-)

For the most part, this is a less-than-important issue for me, as it's not 
all that hard to mark a volume as recyclable. I already have a script that 
I can run that checks each library for tapes marked recycable, and then 
issues a re-label, by pool. Since I am pulling and adding tapes into the 
libraries every day anyway (usually only about 4 per library), marking a 
volume as recyclable is pretty quick. And then the script can be 
automated.

Be more work to do the nsrim, and the mminfos. :-) Altho that can be 
scripted and scheduled, too.

Thanks
