Clone an NVMe namespace with System Manager - ONTAP 9.7 and earlier
You can use ONTAP System Manager classic (available in ONTAP 9.7 and earlier) to quickly create another namespace of the same configuration by choosing to clone a namespace. You can map the newly cloned namespace to another host NQN.
You must have a FlexClone license to clone a namespace.
You can clone a namespace with the selected host mapping and associate it with another subsystem.
Click NVMe > NVMe namespaces.
In the NVMe namespaces window, select the namespace you want to clone.
You can rename the cloned namespace if you need a specific name but it is not required.
The dialog provides a default name of the namespace to-be-cloned.
Modify the subsystem mapping for the cloned namespace.
The online, mapped namespace is cloned inside the same SVM with a different name. Host mapping will not be cloned.
