The params you are looking for are in Dedup Phase II no longer Datamover params but FS params.  They are configured using fs_dedupe, see man fs_dedupe. I think you are speaking about the [-savvol_threshold]  Represents the percentage of SavVol space that can be used during  deduplication. Once the specified amount of SavVol is used, deduplication  stops on this file system. Setting this value to zero disables it. The values  range from 0 to 100 and the default value is 90 percent. option.
Hi,  I tried to change the dedupe.savVolThreshold parameter but got the following error message: Error 2225: server_2 :   : invalid operation When checking the parameters with "server_param server_2 -f dedupe -l" the celerra returned an empty list.  All other facilities work fine and show all expected parameters. The system is a NS8G with code 5.6.47-11. Deduplication itself is acivated and working, I'm just missing the parameters. Has anyone ever experienced this?
server_param -f dedupe -l list emtpy?
