-1. Create a bdev (Block Device) from an RBD image:
-
-    ```bash
-    nvmeof-cli create_bdev --pool rbd --image demo_image --bdev demo_bdev
-    ```
-
 1. Create a subsystem:
 
     ```bash
-    nvmeof-cli create_subsystem --subnqn nqn.2016-06.io.spdk:cnode1 --serial SPDK00000000000001
+    cephnvmf subsystem add --subsystem nqn.2016-06.io.spdk:cnode1
     ```
 
 1. Add a namespace:
 
     ```bash
-    nvmeof-cli add_namespace --subnqn nqn.2016-06.io.spdk:cnode1 --bdev demo_bdev
+    cephnvmf namespace add --subsystem nqn.2016-06.io.spdk:cnode1 --rbd-pool rbd --rbd-image demo_image
     ```
 
 1. Create a listener so that NVMe initiators can connect to:
 
     ```bash
-    nvmeof-cli create_listener ---subnqn nqn.2016-06.io.spdk:cnode1 -g gateway_name -a gateway_addr -s 4420
+    cephnvmf listener add ---subsystem nqn.2016-06.io.spdk:cnode1 -g gateway_name -a gateway_addr -s 4420
     ```
 
 1. Define which hosts can connect:
 
     ```bash
-    nvmeof-cli add_host --subnqn nqn.2016-06.io.spdk:cnode1 --host "*"
+    cephnvmf host add --subsystem nqn.2016-06.io.spdk:cnode1 --host "*"
     ```
