  • ONTAP 9.9
  • SnapMirror Business Continuity (SM-BC)
  • Asynchronous SnapMirror
  • Fan-out

Description

SM-BC supports fan-out configurations. Your source volume can be mirrored to an SMBC destination endpoint and to one or more asynchronous SnapMirror relationships.
 
If you experience a failover on the SM-BC destination, the asynchronous SnapMirror destination will become unhealthy, and you must manually restore protection by deleting and recreating the relationship with the asynchronous SnapMirror endpoint.
 
Note: Fan-out configurations are supported with the MirrorAllSnapshots policy, and, beginning with ONTAP9.11.1, the MirrorAndVault policy. Beginning in ONTAP 9.11.1, fan-out configurations in SM-BC are not supported with XDPDefault policy.
