SVM DR Fan Out in 9.6

WAYNEWATKINS — Wed, 04 Dec 2019 10:11:48 GMT

Hi,

Has anyone successfully configured an SVM DR Fan-Out configuration? According to this document https://kb.netapp.com/app/answers/answer_view/a_id/1075580/~/can-svm-dr-be-used-in-a-fan-out-configuration%3F- it is supported since 9.4 but I'm getting the error when trying to setup the second relationship that the source Vsevere is already in a DR relationship.

Thanks

Hmm, did you create both fan-out relations with identity-preserve true?

cause if yes then it is not supported

https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.pow-dap%2FGUID-B9E36563-1C7A-48F5-A9FF-1578B99AADA9.html

Starting with ONTAP 9.4, fan-out. You can fan-out to two destinations only.

By default, only one -identity-preserve true relationship is allowed per source SVM.

And thank you for mentioning KB - we will update it

@sergey : Good catch, I see the bit 'identity-preserve ' is covered in the release notes for 9.4 but KB needs update.

Can this also be updated or made clear ?
The KB example shows - Two separate Clusters for SVM DR fan-out from source: cluster-a, i.e To cluster-b & cluster-c. However, fan-out could be 2 destinations SVM on the same cluster-b as well ? Or, it has to be two separate clusters. hmm.. !

Thanks!

quckly checked in a lab

it is not possbile to have 2 SVM DR relatiosnhips from the same source to only one destination cluster

Error: command failed: Source Vserver "data" is already in a Vserver DR relationship with another
Vserver in this cluster.

which make sense

Sorry for the delayed response.

Thanks for your response. I just question whether this is truly SVM-DR Fanout?

I see the KB updated. Great thanks.

Hi, I've a question, can we have two SVM-DR from source SVM to two different clusters

1. source SVM to DR-cluster1 - identity-preserve false

2. source SVM to DR-cluster2 - identity-preserve true

Any suggestions?
