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.

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 <destination_SVM>:<destination_volume>

    cluster2::> snapmirror quiesce -destination-path vs1_dr:vol1

  2. From the destination cluster, delete the existing SnapMirror synchronous relationship:

    snapmirror delete -destination-path <destination_SVM>:<destination_volume>

    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 <destination_SVM>:<destination_volume>

    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 <destination_SVM>:<destination_volume> -policy Sync|StrictSync

    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 <destination_SVM>:<destination_volume>

    cluster2::> snapmirror resync -destination-path vs1_dr:vol1
