Converting the mode of a SnapMirror Synchronous relationship

Starting 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.

About this task

You cannot modify the policy of a Snapmirror Synchronous relationship to convert its mode.

Steps

  1. From the destination cluster, quiesce the existing SnapMirror Synchronous relationship: snapmirror quiesce -destination-path dest_SVM:dest_volume
    Example
    cluster2::> snapmirror quiesce -destination-path vs1_dr:vol1
  2. From the destination cluster, delete the existing SnapMirror Synchronous relationship: snapmirror delete -destination-path dest_SVM:dest_volume
    Example
    cluster2::> snapmirror delete -destination-path vs1_dr:vol1
  3. 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
    Example
    cluster1::> snapmirror release -relationship-info-only true -destination-path vs1_dr:vol1
  4. 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
    Example
    cluster2::> snapmirror create -source-path vs1:vol1 -destination-path vs1_dr:vol1 -policy Sync
  5. From the destination cluster, resynchronize the SnapMirror relationship: snapmirror resync -destination-path dest_SVM:dest_volume
    Example
    cluster2::> snapmirror resync -destination-path vs1_dr:vol1
