Bidirectional Snapmirror on 7 mode Ontap 8.2

knowledgeexchange — Thu, 05 Jun 2025 04:32:14 GMT

Hi I have created one dedicated volume on two sites and created the snapmirror relation between them.

filer1:/vol/Vola -> filer2:/vol/volb

Also, again created the snapmirror for the viceversa case.

filer2:/vol/Volb -> filer1:/vol/vola.

Because I want both sites to act as a failover to each on them.

Attached is the current scenario. Please suggest if above is feasible or not.

Are you using qtree snapmirror for vmware? - You shouldn't use qtrees with vmware...

Also, I would suggest doing to another volume and used volume based

Are you saying 2 different volumes on each site and configure snapmirror on each of them. But here I want data to replicate between one datastore only. I want to migrate some critical vm on both the sides to the snapmirrored datastore so that during failover our vms are safe to continue. but if i will create two volume that wont be feasible. I want synchronization to be bidirectional.

I don't understand your intention about this.

you do mirror one volume to a second location and the way back in the same manner ... btw. I wonder, Ontap allow that.

have you ever heard about sync SM feature ? Or at least async ??
