Following a change which took place to upgrade NetApp OTV to 9.12, we experienced issues with our “many to one” SRM setup which is in place for various migrations.

Effectively it will now only run in a “one to one” setup.

 

This worked before. But now it seems that only the last OTV you register will work, overwriting the previous one. (We need to upgrade OTV to 9.12 in order to support bringing our clusters ONTAP versions to 9.12 so there is no option to rollback).

 

NetApp support have directed us to this KB: Storage Replication Adapter: How to configure SRA in a SRM Shared Recovery Site - NetApp Knowledge Base

Which suggests that to support this configuration the 2nd OTV needs to be run in VCF mode.

However, in the guide for configuring VCF: VMware Cloud Foundation mode of deployment for ONTAP tools (netapp.com)

It states: “You can only work with vVols datastores in the VCF deployment mode.”

We are using NFS datastores, not vVols.

 

Does anyone have experience of this set up? Will it work as they have suggested? Or is there another way to register multiple OTV’s to the one VC?

 

TIA

Chris.
