Snap reserve SVM DR

Hi,

i'm having some troubles modifying snap-reserve on three SVM DR target volumes. I'm getting events in OCUM "Volume Snapshot Reserve Space Full" an "Days to full".

Now,  you can't modify this option on target volumes, so modified -percent-snapshot-reserve to 0 on both data volumes and root volume on source SVM => no result, target snap-reserve stays at 5%.

When i try to modify the option on target volume: "Error: command failed: This operation is not permitted on a Vserver that is configured as the destination for identity preserve Vserver DR."

Any idea howto modify this option on the target volumes?
