Based on my last experience, no. You can get a list / inventory of the tapes and do manual reclaims to return the tapes to scratch. On the other hand, when you get a fair bit of data off the VTS backend tapes, turn reclaim on and let it churn then turn it back off. How much churning will depend on the reclaim thresholds you choose. Would be glad to discuss off list if you wish. Best Regards, Doug

We have a 3494 tape library that is currently exclusively being used as physical (stacked) tapes for a 3494-B20 VTS. We're in the process of migrating off this hardware so we have no new allocations going to the B20 and subsequently to the 3590 tapes behind it in the 3494. So as to minimize the churn in the physical tape library, we essentially have tape reclamation shut off. In looking at the graphs generated on the 3494 console, I'm not seeing either the "active data distribution (count of tapes and the percentage of active data on them)" or the "active data (Gigabytes of active data in the library)" going down. I know we have taken a significant amount of data out of the library over the past 30 days, either by migrating it to our replacement library or by deleting/scratching logical tapes that we deemed unnecessary. So my question is this: Should I be seeing these numbers dropping or will they not drop because I'm not reclaiming tapes?
