Beginning with ONTAP 9.5, SnapMirror Synchronous relationships are supported. You can convert the mode of a SnapMirror Synchronous relationship from StrictSync to Sync or vice versa.
You cannot modify the policy of a Snapmirror Synchronous relationship to convert its mode.
-
From the destination cluster, quiesce the existing SnapMirror Synchronous relationship:
snapmirror quiesce -destination-path dest_SVM:dest_volume
cluster2::> snapmirror quiesce -destination-path vs1_dr:vol1
-
From the destination cluster, delete the existing SnapMirror Synchronous relationship:
snapmirror delete -destination-path dest_SVM:dest_volume
cluster2::> snapmirror delete -destination-path vs1_dr:vol1
-
From the source cluster, release the SnapMirror relationship without deleting the common Snapshot copies:
snapmirror release -relationship-info-only true -destination-path dest_SVM:dest_volume
cluster1::> snapmirror release -relationship-info-only true -destination-path vs1_dr:vol1
-
From the destination cluster, create a SnapMirror Synchronous relationship by specifying the mode to which you want to convert the SnapMirror Synchronous relationship:
snapmirror create -source-path vs1:vol1 -destination-path dest_SVM:dest_volume -policy Sync|StrictSync
cluster2::> snapmirror create -source-path vs1:vol1 -destination-path vs1_dr:vol1 -policy Sync
-
From the destination cluster, resynchronize the SnapMirror relationship:
snapmirror resync -destination-path dest_SVM:dest_volume
cluster2::> snapmirror resync -destination-path vs1_dr:vol1
