After setting up a SnapMirror active sync relationship, to ensure automatic failover in case of site failure, you must:

Map the LUNs on the secondary site, so they are accessible during a failover.

Change the service policy on the SAN LIFs to enable multipathing and ALUA support, ensuring paths are correctly managed between primary and secondary sites.

The SnapLock Compliance mode provides WORM (Write Once, Read Many) protection that is irrevocable, even by administrators, and not removable by disk zeroing or reinitialization. This satisfies stringent regulatory and tamper-proof data protection requirements.

Before converting a SnapMirror Synchronous relationship to SnapMirror active sync, you must unmap all LUNs on the destination volumes. This is required to avoid access conflicts, as SnapMirror active sync introduces active-active multipath access and centralized coordination of LUN presentation.

When using the -quick-resync true option in SnapMirror, storage efficiencies such as deduplication and compression are not preserved on the original source during resync. This means that efficiencies will be lost on the source volume, and data will be rehydrated to its full form during transfer.

In an 8-node MetroCluster IP configuration, if one DR group (i.e., one HA pair at a site) fails and the ONTAP Mediator is in use, MAUSO will be triggered. ONTAP 9.14.1 supports automatic detection and unplanned switchover for such cases using the Mediator to validate the failure and coordinate the takeover.

If the volume was deleted within the retention window (by default, 12 hours), ONTAP allows you to quickly restore the deleted volume directly from System Manager, as it is still in the volume recovery queue. This process typically takes less than a minute and is the fastest recovery option in this scenario.
