Hi guys,

This is the supported matrix of failure scenarios I found into doc (check image)

Now my question:
we know that SM-AS supports Planned Failover,that is, I can force CG mirror to become Primary and viceversa.
In the case of the Mediator becomes unavailable, is it still possible to switch the Primary-Mirror roles between clusters?
It's not detailed in the doc what are the prerequisites for Planned Failover..

The ONTAP Mediator must be configured, connected, and in quorum.

Perform a planned failover of clusters in a SnapMirror active sync ...

You can perform a planned failover to test your disaster recovery configuration or to perform maintenance on the primary cluster.

thank you Darkstar.

One more question:
I can have multiple ConsistencyGroups (CG) and I should be able to have a CG1-Primary on site 1 and it's CG1-mirror on site 2, but at the same time a CG2-Primary at site2 and a CG2-Mirror at site1.
This way the failcase scenarios applies to every single relationship, right?

yes, the failover is per-cg in SnapMirror active sync. You can failover each CG individually
