In ONTAP System Manager, click Storage > NVMe Namespaces and then click Add.

If you are running ONTAP 9.8 or later and you want to disable QoS or choose a custom QoS policy, click More Options and then, under Storage and Optimization select Performance Service Level.

Zone your FC switches by WWPN. Use one zone per initiator and include all target ports in each zone.

On your host, discover the new namespaces.

Initialize the namespace and format it with a file system.

Verify that your host can write and read data on the namespace.

Verify that the SVM is configured for NVMe:

vserver show -vserver <svm_name> -fields allowed-protocols

Create the NVMe namespace:

vserver nvme namespace create -vserver <svm_name> -path <path> -size <size_of_namespace> -ostype <OS_type>

Create the NVMe subsystem:

vserver nvme subsystem create -vserver <svm_name> -subsystem <name_of_subsystem> -ostype <OS_type>

Verify that the subsystem was created:

vserver nvme subsystem show -vserver <svm_name>

Obtain the NQN from the host.

Add the host NQN to the subsystem:

vserver nvme subsystem host add -vserver <svm_name> -subsystem <subsystem_name> -host-nqn <Host_NQN>

Map the namespace to the subsystem:

vserver nvme subsystem map add -vserver <svm_name> -subsystem <subsystem_name> -path <path>

Verify that the namespace is mapped to the subsystem:

vserver nvme namespace show -vserver <svm_name> -instance
