Commands for managing SnapMirror relationships

Data ONTAP includes many commands for managing SnapMirror relationships of FlexVol volumes and Infinite Volumes.

You must have installed a SnapMirror license before you can manage SnapMirror relationships.

If you want to... Use this command...
Abort an active transfer snapmirror abort

You can use the snapmirror show command to determine the status of the abort operation.

If you are using Infinite Volumes, management tasks must be performed on the Infinite Volume and not its individual constituents.

Make a data protection mirror copy destination writeable snapmirror break

This command must be used from the destination Storage Virtual Machine (SVM).

You must not have I/O traffic running on the volume when you use this command.

Create a new data protection mirror relationship snapmirror create

This command must be used from the destination SVM.

If you are using Infinite Volumes, you can create data protection mirror relationships between clusters only, not within a cluster.

Delete a data protection mirror relationship snapmirror delete

This command must be used from the destination SVM.

If you are using Infinite Volumes, management tasks must be performed on the Infinite Volume and not its individual constituents.

Start a baseline transfer snapmirror initialize

This command must be used from the destination SVM.

Display a list of data protection mirror relationships whose source endpoints are in the current SVM snapmirror list-destinations

This command must be used from the source SVM.

Modify a data protection mirror relationship snapmirror modify

This command must be used from the destination SVM.

Display a list of data protection and load-sharing mirror relationships or display the state of a scheduled transfer for a SnapMirror relationship snapmirror show

The information that this command shows is updated periodically; therefore, any changes to a relationship might not be displayed immediately.

This command must be used from the destination SVM.

Display a list of completed SnapMirror operations snapmirror show-history

This command must be used from the destination SVM or cluster.

This task does not support relationships with a "Pre 8.2" relationship capability, for example, load-sharing mirror relationships.

Disable future transfers for a mirror relationship snapmirror quiesce

This command must be used from the destination SVM.

Enable future transfers for a mirror relationship snapmirror resume

This command must be used from the destination SVM.

Start a resynchronize operation snapmirror resync

This command must be used from the destination SVM.

You must not have I/O traffic running on the volume when you use this command.

Quotas are turned off on the volume you resynchronize. After resynchronizing, if you had quotas on the volume before the resynchronization you must reactivate quotas on the volume.

Attention: A resynchronize operation can cause data loss on the destination volume because the command can remove the exported Snapshot copy on the destination volume.
Add an owner to prevent premature deletion of a user-created Snapshot copy for a SnapMirror-to-SnapVault cascade configuration snapmirror snapshot-owner create

A typical use case is to preserve an application-consistent Snapshot copy.

This task is not supported for Infinite Volumes.

Delete an owner used to preserve a user-created Snapshot copy for a SnapMirror-to-SnapVault cascade configuration snapmirror snapshot-owner delete

This task is not supported for Infinite Volumes.

Show all the Snapshot copies with owners that were added using the snapmirror snapshot-owner create command snapmirror snapshot-owner show

This task is not supported for Infinite Volumes.

Start an incremental transfer snapmirror update

This command must be used from the destination cluster.

If you are using Infinite Volumes, aggregate requirements must be met before performing the incremental transfer. Management tasks must be performed on the Infinite Volume and not its individual constituents.

You can disregard error messages that result from updating a SnapMirror relationship from a Snapshot copy that exists on the destination volume. Any such messages are for support use.

Create a new policy for a data protection mirror relationship snapmirror policy create
Delete a policy of a data protection mirror relationship snapmirror policy delete
Add a new rule to a SnapVault relationship snapmirror policy add-rule
Modify an existing rule in the policy of a SnapVault relationship snapmirror policy modify-rule
Modify a policy of a data protection mirror relationship snapmirror policy modify
Remove a rule from the policy of a data protection mirror relationship snapmirror policy remove-rule
Show the policy of a data protection mirror relationship snapmirror policy show
Copy data to a volume snapmirror restore

Quotas are turned off on the volume you restore. After the restore, you must activate quotas on the volume, if you had quotas on the volume before the restore.

This task is not supported for Infinite Volumes.

Remove the SnapMirror relationship information from the source SVM snapmirror release

This command must be used from the source SVM.
