In the past, I have deleted some volumes with read/write errors with the
delete volume XXXX discard=yes command.  My assumption has always been
that this is safe since the copy storage pool has a copy should there
ever be a problem.  In hindsight it seems that that assumption may not
always be valid.  If the data resides on a bad tape, I may not be
readable to create the copy.  Deleting the only volume that has the
archive would then delete the archive entirely.

If this is possible, and it seems that it is, then I need to verify what
data is on a tape and that it is in fact in the copy storage pool before
it can be deleted.  I do not know of a way to do this in TSM.

How did you destroy them and were they primary pool volumes?
Following the correct procedure (and you have a good copy), you should
not
loose data.
