Breaking the SnapMirror relationship

You must quiesce and break the SnapMirror relationship to activate the destination volume. After quiescing, future SnapMirror data transfers are disabled.

Before you begin

The destination volume must be mounted on the destination SVM namespace.

About this task

You must perform this task from the destination cluster.

Before performing the break operation, run the snapmirror quiesce command to disable future transfers for a SnapMirror relationship. If there is no transfer in progress, the relationship becomes quiesced.

If there is a transfer in progress, it is not affected, and the relationship becomes quiescing until the transfer is completed. If the current transfer aborts, it will be treated like a future transfer and will not restart. If the quiesce command is applied to a load-sharing (LS) SnapMirror relationship, all the relationships in the LS set will be quiesced.

When a SnapMirror relationship is quiesced, it remains quiesced across reboots and failovers.

  1. From the destination cluster CLI, run the following command to quiesce the existing relationship: SnapMirror Synchronous relationship:snapmirror quiesce -destination-path dest_SVM:dest_volume

    Example

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

  2. After the SnapMirror relationship is quiesced, run the snapmirror break command to break the relationship.

    Example

    cluster2::> snapmirror break -destination-path vs1_dr:vol1
    [Job 128] Job succeeded: SnapMirror Break Succeeded
    The status of the SnapMirror relationship is displayed as broken off.
  3. After the relationship is broken off, run the snapmirror show command to check the status of the broken SnapMirror relationship.

    Example

    Cluster2::> snapmirror show

    Source          Destination   Mirror  Relationship Total             Progress Last
     Path     Type    Path        State    Status      Progress  Healthy  Updated
