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.

A group of load-sharing mirror destination volumes that replicate from the same source volume is referred to as a load-sharing mirror set.

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.

List the SVM source root volume and protection volumes.

Now create a Load sharing (LS) snapmirror relationship to other destination volumes.

Now initialize the relationship using the following command.

List the status of the root volume in System Manager.

These are the two destination LS shared volumes.

Now volumes are in the LS type.

SVM root volume restore (Recovery) :

If the storage virtual machine (SVM) root volume becomes unavailable and you have protected it with a set of load-sharing mirrors, you can promote one of the mirrored volumes and then rename it to take the place of the original SVM source volume.

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.

Now use the snapmirror promote command to restore the root volume.
