This one is positive. TSM 5.3.3.0 on AIX 5.3 ML-4
One of the new features of TSM 5.3 is the ability to have more than one reclamation process for a storage pool. To whoever designed and implemented that, I say "Thank you." Our copypool is hosted on a 5-year old HP DLT library with four DLT8000 drives. Average sustained throughput is 8 MB/s per drive. We run maintenance weekly, including copypool reclamation. Normally that reclamation starts on Tuesday evening and runs through mid-day Thursday, re-writing about 500 GB of data to the output volumes. Last week I configured the copypool to use two reclamation processes. Reclamation started at 6 PM Tuesday as normal. When I came in Wednesday morning, it was finished and had written about 480 GB. That's 1-1/2 _DAYS_ faster than before! So, again, thanks for the great enhancement. Tab Trepagnier TSM Administrator Laitram, L.L.C.
