SnapMirror over Multiple Paths

nsitps1976 — Thu, 05 Jun 2025 05:56:47 GMT

Is it possible to use SM over multiple paths as to mirror half the volumes over one path and the other half over a second path on the SAME filer?

Looking at the backup and recovery guide snapmirror.conf file example suggests the all volumes would either multiplex over both interfaces or use the same active interface in the failover mode. It would be good if I could use failover mode and specify different active interfaces (using failover mode) for different SM relationships.

Hi nsitps1976 ,

It's possible if you creat 2 qtree under the volume. Each qtree have half the volume.

Good luck

Sorry, I did not make myself clear. I am using a SAN environment in which LUNs do not reside with qtrees.

Your answer suggests you can have mutual connection entries within snapmirror.conf (with different active interfaces) and then use these to create your snapmirror relationships (and hence split your volumes over two separate interfaces. Is this correct?

Yes nsitps1976 ,

That's correct.
