If the root volume of a Storage Virtual Machine (SVM) becomes unavailable, clients cannot mount the root of the namespace. In such cases, you must restore the root volume by promoting another volume or creating a new root volume to facilitate data access to the clients.
SVM root volume must be protected by using the load-sharing mirror copy or data-protection copy.
You can promote any volume that does not have other volumes junctioned to it.
When a new volume is promoted as the SVM root volume, the data volumes are associated with the new SVM root volume.
You must mount the new root volume by using the volume mount command.
