ONTAP 9.1 SVM ROOT VOLUME PROTECTION

SVM ROOT VOLUME PROTECTION:

To protect the Storage Virtual Machine (SVM) namespace root volume, you can create a load-sharing mirror volume on every node in the cluster, including the node in which the root volume is located. Then you create a mirror relationship to each load-sharing mirror volume

and initialize the set of load-sharing mirror volumes.

Creating load-sharing mirror volumes

For protecting the root volume of a Storage Virtual Machine (SVM), you must create a FlexVol volume on every node of the cluster and designate it as a load-sharing mirror destination.

Creating load-sharing mirror relationships

You must create a load-sharing mirror relationship between the root volume of the Storage Virtual Machine (SVM) and each of the load-sharing mirrors created for the SVM root volume protection.

Create LS mirror relationship first.

Then initialize  the load share mirror set.

Now it is transferred and snapmirrored.

Check field type of volumes.

Restoring the SVM root volume by promoting a load-sharing mirror

If the Storage Virtual Machine (SVM) root volume becomes unavailable, read access is provided through the load-sharing mirror volumes. To enable write access to the SVM root volume, you must promote one of the load-sharing mirror volumes and rename it with the original SVM root volume name.

For restore, promote any other volume act as a SVM root volume.

Now check the volume type.
