Configure SnapMirror active sync on ASA r2 systems

Configure SnapMirror active sync to create a copy of your data at a secondary site and enable your host applications to automatically and transparently failover in the event of a disaster.

On ASA r2 systems, SnapMirror active sync supports symmetric active/active configurations. In a symmetric active/active configuration, both sites can access local storage for active I/O.

Note If you are using the iSCSI or FC protocol and use ONTAP tools for VMware Sphere, you can optionally use ONTAP Tools for VM ware to configure SnapMirror active sync.
Before you begin

Create a consistency group on the primary site with new storage units. If you want to create a non-uniform symmetric active/active configuration, also create a consistency group on the secondary site with new storage units.

Learn more about non-uniform symmetric active/active configurations.

Steps

  1. In System Manager, select Protection > Consistency groups.

  2. Hover over the name of the consistency group you want to protect with SnapMirror active sync.

  3. Select three vertical blue dotsand then select Protect.

  4. Under Remote protection, select Replicate to a remote cluster.

  5. Select an existing cluster peer or choose to Add a new one.

  6. Select the storage VM.

  7. For the replication policy, select AutomatedFailOverDuplex.

  8. If you are creating a non-uniform symmetric active/active configuration, select Destination settings; then input the name of the new destination consistency group you create before beginning this procedure.

  9. Select Save.

Result

SnapMirror active sync is configured to protect your data so that you can continue operations with near zero recovery point objective (RPO) and near zero recovery time objective (RTO) in the event of a disaster.
