f. Make a note of the node ID of the node.
2. After you identify the node, move iSCSI sessions away from the node by using the following API call:
wget --no-check-certificate -q --user=<USER> --password=<PASS> -O - --post
-data '{ "method":"MovePrimariesAwayFromNode", "params":{"nodeID":<NODEID>} }'
https://<MVIP>/json-rpc/8.0
MVIP is the MVIP IP address, NODEID is the node ID, USER is the user name you configured in the
NetApp Deployment Engine when you set up NetApp HCI, and PASS is the password you configured in the
NetApp Deployment Engine when you set up NetApp HCI.
3. Select Cluster > Drives to remove the drives associated with the node.

5. Use the following API call to shut down the node:
wget --no-check-certificate -q --user=<USER> --password=<PASS> -O - --post
-data '{ "method":"Shutdown", "params":{"option":"halt", "nodes":[ <NODEID>]}
}' https://<MVIP>/json-rpc/8.0
MVIP is the MVIP IP address, NODEID is the node ID, USER is the user name you configured in the
NetApp Deployment Engine when you set up NetApp HCI, and PASS is the password you configured in the

b. Pull down the cam handle on the right side of each node, and pull the node out using both the cam
handles.
8. Reinstall the node into the chassis by pushing the node in until you hear a click.
The labels you had attached to the node before you removed it help guide you.

Ensure that you support the node from under when you install it. Do not use excessive
force while pushing the node into the chassis.

If installing into the new chassis, ensure that you install the node into its original slot in
the chassis.
9. Install the drives into their respective slots in the node by pressing down the cam handle on each drive until
