Just wanted to do a quick sanity check, is there any way to have SnapMirror replication go both directions between sites? We are running cDOT 9.x at both locations.
I came across some older posts (several years ago) that seem to indicate that bi-directional snapmirror would not be possible. Just wondering if this might have changed with cDOT 9.x capabilities?
Thanks, Eric

Depends on what you mean exactly. For the same volume? No, of course not. For different volumes? Sure, works just fine, as you'd expect. You're better off using XDP relationships, though, due to ONTAP version inter-dependencies.

AFAIK this has always worked, even back in the DOT7G days. But I only really started using cDOT with 8.3, so 8.0-8.2 might have had limitations.

Hmm, I do it in 7m, seems weird that you would not be able to do that in cm. To be clear, we are talking about different volumes obviously, right? Site1_volume ----> mirror_Site1_volume and site2_volume ----> mirror_site2_volume

I think the OP wants to do bi-drectional vaults with the *same* volume pair.
You can't do that. you sure can do vaults in various directions with different volume pairs, which is a handy way to protect data across your various sites.

For the same data set, bi-directional, you might want to POC Peer Software. They PeerSync bi-directional and also have PeerLink which locks files on either side while keeping in sync. FPOLICY is used for real time event notification without file scans.
