To enable node3 and node4 to communicate with each other in the cluster and
with the network after the upgrade, you need to ensure the physical ports are correctly
configured with the settings for the intended use, such as cluster, data, and so
on.
About this task
You need to perform these steps on node3 and node4.
Note: The
following command examples refer to "node1" because at this stage in the
procedure the replacement nodes "node3" and "node4" are actually named "node1"
and "node2".
Procedure
-
If your system is running ONTAP 9.8, STOP. You must use the procedure in
Mapping network ports using ONTAP 9.8.
-
Locate the port and LIF configuration information for node1 and node2 that you
recorded in Step 3.
-
Locate the information for ports, broadcast domains, and IPspaces that you
recorded in Step 3.
-
Make the following changes:
-
Boot node3 and node4 to the cluster prompt if you have not already
done so.
-
Add the correct ports to the Cluster broadcast domain: network port
modify -node node_name -port
port_name -mtu 9000 -ipspace
Cluster
This example adds Cluster port e1b on node1
:
network port modify -node node1 -port e1b -ipspace
Cluster -mtu 9000
-
Migrate the LIFs to the new ports, once for each LIF:
network interface migrate -vserver vserver_name -lif lif_name -source-node node1 -destination-node node1
-destination-port port_name
SAN data LIFs can be migrated only when they are offline.
-
Modify the home port of the Cluster LIFs: network interface modify
-vserver Cluster -lif lif_name
–home-port port_name
-
Remove the old ports from the Cluster broadcast domain: network port
broadcast-domain remove-ports -ipspace Cluster -broadcast-domain
Cluster -ports node1:port
-
Display the health state of
node3 and node4: cluster show -node node1 -fields health
-
Modify the VLAN and ifgrp config to match the
new controller physical port layout.
-
Delete the node1 and node2 ports that no longer exist on node3 and node4
(advanced privilege level): network port delete
-node node1 -port port_name
-
Adjust the node-management broadcast domain and migrate the node-management
and cluster-management LIFs if necessary:
-
Display the home port of a LIF: network interface show
-fields home-node,home-port
-
Display the broadcast domain containing the port: network
port broadcast-domain show -ports node_name:port_name
-
Add or remove ports from broadcast domains as necessary:
network port broadcast-domain
add-portsnetwork port broadcast-domain
remove-ports
-
Modify a LIF’s home port if necessary: network interface
modify -vserver vserver_name -lif
lif_name –home-port port_name
-
Adjust the intercluster broadcast domains and migrate the intercluster LIFs,
if necessary, using the commands in Step 7.
-
Adjust any other broadcast domains and migrate the data LIFs, if necessary,
using the commands in Step 7.
-
Adjust all the LIF failover groups: network interface modify
-failover-group failover_group
-failover-policy failover_policy
The following command sets the failover policy to
broadcast-domain-wide and uses the ports in failover
group fg1
as failover targets for LIF data1
on node1
: network interface modify
-vserver node1 -lif data1 -failover-policy broadcast-domain-wide
-failover-group fg1
-
Display node3 and node4 's network port attributes: network port show -node
node1
After you finish
You have completed mapping the
physical ports. To complete the upgrade, go to
Performing final upgrade steps in ONTAP 9.7 or earlier.
