Quiescing a vault relationship
You can use System Manager to disable data transfers to the destination FlexVol volume by quiescing the vault relationship.
Click Protection > Volume Relationships.
Select the relationship for which you want to stop the scheduled data transfers, and click Operations > Quiesce.
In the Quiesce window, click Quiesce.
If there is no transfer in progress, the transfer status is displayed as Quiesced. If a transfer is in progress, the transfer is not affected, and the transfer status is displayed as Quiescing until the transfer is complete.
