Create an SVM disaster recovery relationship for FlexGroup volumes

Beginning with ONTAP 9.9.1, you can create SVM disaster recovery (SVM DR) relationships using FlexGroup volumes. An SVM DR relationship provides redundancy and the ability to recover FlexGroups in the event of a disaster by synchronizing and replicating the SVM configuration and its data. A SnapMirror license is required for SVM DR.

Before you begin

You cannot create a FlexGroup SVM DR relationship with the following applies.

  • A FlexClone FlexGroup configuration exists

  • The FlexGroup volume is part of a cascading relationship

  • The FlexGroup volume is part of a fanout relationship, and your cluster is running an ONTAP version earlier than ONTAP 9.12.1. (Beginning with ONTAP 9.13.1, fanout relationships are supported.)

About this task

  • All nodes in both clusters must be running the same ONTAP version as the node on which SVM DR support was added (ONTAP 9.9.1 or later).

  • The SVM DR relationship between the primary and secondary sites should be healthy and should have enough space on both the primary and secondary SVMs to support the FlexGroup volumes.

  • Beginning with ONTAP 9.12.1, FabricPool, FlexGroup, and SVM DR can work in conjunction. In releases earlier than ONTAP 9.12.1, any two of these features worked together, but not all three in conjunction.

  • When you create a FlexGroup SVM DR relationship in which the FlexGroup volume is part of a fanout relationship, you should be aware of the following requirements:

    • The source and destination cluster must be running ONTAP 9.13.1 or later.

    • SVM DR with FlexGroup volumes supports SnapMirror fanout relationships to eight sites.

Steps

  1. Create an SVM DR relationship, or use an existing relationship.

    Replicate an entire SVM configuration

  2. Create a FlexGroup volume on the primary site with the required number of constituents.

    Creating a FlexGroup volume.

    Wait until FlexGroup and all of its constituents are created before proceeding.

  3. To replicate the FlexGroup volume, update the SVM at the secondary site: snapmirror update -destination-path destination_svm_name: -source-path source_svm_name:

    You can also check if a scheduled SnapMirror update already exists by entering snapmirror show -fields schedule

  4. From the secondary site, verify that the SnapMirror relationship is healthy: snapmirror show

    cluster2::> snapmirror show
                                                                       Progress
Source            Destination Mirror  Relationship   Total             Last
Path        Type  Path        State   Status         Progress  Healthy Updated

                                      Idle           -         true    -

  5. From the secondary site, verify that the new FlexGroup volume and its constituents exist: snapmirror show -expand

    cluster2::> snapmirror show -expand
                                                                       Progress
