SnapMirror active sync enables business services to continue operating even through a complete site failure, supporting applications to fail over transparently using a secondary copy. Neither manual intervention nor additional scripting is required to trigger a failover with SnapMirror active sync.

For more information on SnapMirror active sync refer SnapMirror active sync overview.

For SnapMirror active sync, ensure that you have met the various hardware, software, and system configuration requirements. For information refer Prerequisites

The plug-ins supported for this feature are SnapCenter Plug-in for SQL Server, SnapCenter Plug-in for Windows, SnapCenter Plug-in for Oracle database, SnapCenter Plug-in for SAP HANA database, SnapCenter Plug-in for Microsoft Exchange Server, and SnapCenter Plug-in for Unix.

After installing the SnapCenter Server and plug-ins, you should enable the REST API for SnapCenter to detect SnapMirror active sync relationships.

  • On the SnapCenter server host, edit the C:\Program Files\NetApp\SMCore\SMCoreServiceHost.dll.config file to modify the value of the IsRestEnabledForStorageConnection parameter to true and then restart the SnapCenter SMCore service.

  • On the Windows plug-in hosts:

    • Edit the C:\Program Files\NetApp\SnapCenter\SMCore\SMCoreServiceHost.dll.config file to modify the value of the IsRestEnabledForStorageConnection parameter to true.

    • Edit the C:\Program Files\NetApp\SnapCenter\SMCore\SnapDriveService.dll.config file to modify the value of the IsRestEnabledForStorageConnection parameter to true.

    • Restart the SnapCenter SMCore service.

Note To support host initiator proximity in SnapCenter, it's value, either source or destination should be set in ONTAP.

The use cases not supported in SnapCenter:

  • If you convert the existing asymmetric SnapMirror active sync workloads to symmetric by changing the policy on the SnapMirror active sync relationships from automatedfailover to automatedfailoverduplex in ONTAP, the same is not supported in SnapCenter.

  • If there are backups of a resource group (already protected in SnapCenter) and then storage policy is changed on the SnapMirror active sync relationships from automatedfailover to automatedfailoverduplex in ONTAP, the same is not supported in SnapCenter.
