PM question: Creating relationships... volume options

Hi, i've got another question If I'm using relationship and it is using resource pool ... then are the volume options on the just created destination side like:

a) gurantee

b) fractional_reserve

c) snap sched

propagated? From my experiments the answer is no, so this means for example if we have "snap sched 0 0 0" on some FlexVol and PM creates "Back up" relationship the freshly populated volume gets some defaults like "0 2 6@8,20".  PM 3.8.1 here, but the questions stays the same, is this a bug or feature?

-Jakub.

I think the FR settings are copied from the source, but for SV and QSM destination volumes the guarantee is always none.

For a SnapMirror destination volume, yes it will be the replica of the source.

But for SV/QSM relatationship destination volume it will be the below ones.

volume guarntee is none.

snap sched will be disabled.

FR will be 0.

Thanks! Exactly just noticed the "nosnap=on" on the volume options on desitnation side. However the FR=100% (identical like the source).
