HI All

/opt/drd/bin/drd clone -p -v -x overwrite=true -t /dev/disk/disk147

When running the above command, i was presented with the message in the subject field (as below).

 N:Reducing max_physical_extents for volume group: vg110 from 262144 to 2500. The specified value was larger than allowed.
         N:Reducing max_physical_extents for volume group: vg112 from 262144 to 2500. The specified value was larger than allowed.

These happen to be our new NetApp volume groups.

Is this normal behaviour for DRD?  Are these messages of concern?
