Re: empting a read only tape.

There is a solution for almost *every* problem!
1. checko libv <your_lib> <that_ugly_one> checkl=no
2a. upv v <that_ugly_one> acc=dest (for primary)
2b. del v <that_ugly_one> discard=y (for copy)
3a. rest v <that_ugly_one>
3b. ba stg <primary_pool> <copy_pool>

Throw away the tape after step 1 and do not bother yourself with quick
typing (doing quick and dirty mistakes ;o)))

Yes, this is how it works, ...and, This is a Problem.

I frequently make a tape read only if it is having enough I/O errors to
suspect the tape media. So I want to get it out of circulation, perhaps
to send it for recirtification or replacement. (At USD$100/each I do not
casually discard suspect S-DLT tapes!)

But if you are careless about how you do this, it will get reused,
sometimes very quickly. So I always work deliberately - instead of
letting expiration and reclamation remove the data from the suspect
tape, I do a MOVE DATA. Then, with my REUSEDELAY set to 2 days, I have a
chance to grab the tape while it is still Pending.

The best way to remove a suspect tape that is Pending is to do a DELETE
VOL, and then ***IMMEDIATELY*** do a UPDATE LIBVOL <libname> <volname>
STATUS=PRIVATE. If you are slow, it will get reused the very next time
that a scratch tape is needed - there's some kind of logic here that
probably makes sense except in this special circumstance. Then leave it
physically in the library until your next database backup, after which
you can safely remove it.
