Ok. What it looks like has happened is that you ran out of scratch tapes and reclaimation failed because of that. You then added scratch tapes but there was so much to catch up on that it ran out of scratch before actually completing any individual volumes. Assuming that your DRM is working ok and you are getting tapes back if they are reclaimed, this is what I would do.
Set the reclaimation level to 60 (from 97).
Limit the number of tapes the process tries to reclaim at any one time to 5.
Add one scratch tape and start reclaimation.
upd stg OFFSITE-DAILY rec=60 offsitereclaiml=5
<Add one scratch tape>
reclaim stg OFFSITE-DAILY
This should get the first 5 tapes reclaimed reasonably quickly and you should see the status of the tapes changing to PENDING state. I use the follow SQL query to checking pending tapes.
select volume_name, pending_date as "Pending Date " from volumes where status='PENDING' order by pending_date
You should start seeing tapes listed here. As you have a reuse delay of 2 days, any tapes fully reclaimed in the last 2 days will show with this query.
