Hi list,

Could anyone tell me if the performance problem related to reclamation
of copypool data when primary copy resides on disk has been solved ?
I'm asking this because we migrated our TSM server (v 5.2.2.1) on a
beefy p5 550 series, with disk pools large enough to keep one day data,
and reclamation of certain copy pools is horribly slow (lto1 drives,
gives me 2 MB/s for AIX and Windows data, if lucky). 
Problem is that my daily job (copy tapes generation + db backup +
expiration ...) finishes approx. at 10 AM. So, for having decent
reclamation performance during the next step, I would need to flush the
data from disk to tape much too early in the day, therefore penalizing
an eventual restore process during the afternoon.
I need to reclaim approx. 100 GB/day for aix copypool only, and with my
actual throughput, that would mean more than 10 hours processing : I
can't afford that !
Cheers.

Arnaud
