IHAC who has asked me to determine "where the capacity growth" has come from over the past year. He has a DFM/OCC server from which we can (hopefully) mine the historical data.
The challenge is that there are several thousand volumes/datasets and most of them have been migrated into new volumes or renamed over the last year as part of a tech refresh, so to get the historical sizes of many datasets I need to access the size that a since-deleted volume had a year ago.
Is this possible? If yes, how can I access the data? Would OC Report be of assistance in this situation? Thanks in advance for any ideas/advice!
thanks for responding! Custom reports let me select the "Volume Used Capacity" for the deleted volumes, which I take it was the last update of the capacity used before the time of deletion. What I need is not the size when the volume was deleted but at some earlier time, basically a snapshot of the environment on a given day, ideally as a list: 'here are all the volumes that existed on day X and the used capacity for each of these volumes on that day'.
however it complains ("no such object") when I use object IDs listed in the volumes-deleted report, which could be because of my lab environment or it could be because DFM doesn't retain this data for deleted volumes. I'm wondering if I'm going about this the wrong way or if the data I need isn't in DFM.
