The behaviour I've seen says that it can go for a longer time than just
9-5 if you set the number too low or too "into" the chain. Especially if
the number chosen is not the tape with the most to be reclaimed.

I do :

   select volume_name,pct_reclaim,status,pct_utilized -
   from volumes where stgpool_name='COPYPOOL' -
   and pct_reclaim>$1 -
   order by pct_reclaim desc

where $1 is some number like 20 or 30  and then 'dive in' about 10 down.
The logic in ADSM causes all tapes down to this number to be reclamated
simultaneously.  If you TAPEPOOL is collocated then the offsite
reclamation should be more efficient read each onsite tape once to
reclamate the offsite information.
