Issue

Intermittent failures with Consistency Group (CG) Async SnapMirror transfers. The error reported is: "Failed to get information for source volume for setup of transfer. (Failed to start transfer as SnapMirror found an invalid snapshot. Retry the operation.)" This occurs between the source SVM_AUR_PreludeProd:/cg/CG_preaur1vudt03 and the destination SVM_COM_PreludeDR:/cg/CG_preaur1vudt03_dest. The issue started after enabling the snapmirror policy options -enable-sm-created-replication and -enable-acs-replication on the SMBC destination to allow async snapshots to also replicate to the SMBC destination.
