First, you need to see the current security configuration by this command.
Security config show
Now enable the flips by this command & accept x3 prompts.
Security config modify -interface SSL -is-fips-enabled true
Now Run the security config show &you will see that both nodes need to be rebooted.
To do this in a cluster, the easiest way is to open NetApp OnCommand Manager & log in. Next, go to High Availability found under Cluster Settings. By selecting the option under node 1 to take over node 2, reboot node 2 first.
Click on Take Over.
The reboot has started.
Node 2 is offline during reboot.
Do not click on Give back. Wait
Now, Node 2 is online after a while after reboot. Re-homing interfaces can by going to Network, then interfaces & then Send to home.
For Node 1 we will repeat the same process but we will select node 2 and take over node 1
Click Take over as before.
This time, node 1 goes offline
Wait until the “Nodes can take over” message appears.
Check by security config to show if a reboot is still needed, else it’s perfect now.
