PM question: Creating relationships... volume options

jakub_wartak — Thu, 05 Jun 2025 07:09:39 GMT

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.

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).

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