Hi John:
Per the manual, copypool volumes that are acc=unav are still candidates for 
reclamation.
When you change them to acc=readw do you return them onsite to complete the 
reclamation, or does the reclamation process use the primary storage pool as a 
source?

I have also had troubles with this and found that I have tapes that have
been marked unavailable.  I changed them to readwrite and reclamation worked
fine after that.  On the command line type q vol * stg=* acc=unavailable
