Beginning with ONTAP 9.14.1, you can use System Manager to create a volume clone to test SnapMirror failover and disaster recovery without disrupting the active SnapMIrror relationship. When you finish testing, you can clean up the associated data and delete the test volume.

Create a SnapMirror failover test volume

About this task

  • You can perform failover tests on synchronous and SnapMirror asynchronous relationships.

  • A volume clone is created to perform the disaster recovery test.

  • The clone volume is created on the same storage VM as the SnapMirror destination.

  • You can use FlexVol and FlexGroup SnapMirror relationships.

  • If a test clone already exists for the selected relationship, you cannot create another clone for that relationship.

  • SnapLock vault relationships are not supported.

Before you begin

  • You must be a cluster administrator.

  • The SnapMirror license must be installed on the source and destination cluster.

Steps

  1. On the destination cluster, select Protection > Relationships.

  2. Select Menu options icon next to the relationship source and choose Test Failover.

  3. In the Test Failover window, select Test Failover.

  4. Select Storage > Volumes, and verify that the test failover volume is listed.

  5. Select Storage > Share.

  6. Click Add icon and choose Share.

  7. In the Add share window, type a name for the share in the Share Name field.

  8. In the Folder field, select Browse, select the test clone volume, and Save.

  9. At the bottom of the Add share window, choose Save.

  10. Open the share on the client and verify that the test volume has read and write capabilities.

Clean up failover data and delete the test volume

After you have completed failover testing, you can clean up all data associated with the test volume and delete it.

Steps

  1. On the destination cluster, select Protection > Relationships.

  2. Select Menu options icon next to the relationship source and choose Clean Up Test Failover.

  3. In the Clean Up Test Failover window, select Clean Up.

  4. Select Storage > Volumes and verify that the test volume was deleted.
