Stabilizing destinations before a Snapshot copy

You might need to temporarily stop transfers to a destination, by using the snapmirror quiesce command. For example, if you want to create a Snapshot copy of a SnapMirror destination volume or qtree that contains a database, you need to ensure that its contents are stable during the Snapshot copy.


  1. Enter the following command on the system on which you want to block transfers:snapmirror quiesce {dest_volume | /vol/volume_name/qtree_name}
    dest_volume is the name of the destination volume.

    qtree_name is the name of a qtree in volume_name.

    systemA> snapmirror quiesce vol1
    snapmirror quiesce: in progress.
    snapmirror quiesce: vol1: successfully quiesced
    SnapMirror stops any further data transfers to vol1.
    systemA> snapmirror quiesce vol2
    snapmirror quiesce: in progress.
    This can be a long-running operation. Use Control-C to interrupt.
    snapmirror quiesce: vol2: successfully quiesced
    SnapMirror waits for a transfer to finish and stops any further data transfers to vol2.
    systemA> snapmirror quiesce /vol/vol1/qtree1
    SnapMirror stops data transfers to qtree1 in vol1.
    If you use the snapmirror break command on a destination that is quiesced, the quiesce condition is automatically cleared when the destination becomes writable.
    Note: If you decide to abort a SnapMirror quiesce operation, press Ctrl-C or enter the snapmirror resume command at any time.
    A SnapMirror destination volume might have been deleted after the volume was quiesced. If you want to create a SnapMirror destination volume with the same name as the deleted volume, first use the snapmirror release command. This step would ensure that the SnapMirror relationship is set up properly.
