In case it's not obvious I'm a bit of a NetApp newb and inherited some clusters and am in the inventory and monitor stage of taking over administration of them.
Today I noticed that the SVMs have tcp/80, tcp/443 open and load a 404 when you browse to their root URL. This would not be the cluster or node management SVM, but rather various data SVMs. This begs the questions:
- Why do the SVMs have web servers?
- Why do they load a 404 as the root page?
- I see docs on shutting this off via 'system services firewall' command set, but are there any reasons why a SVM web port should be open?
See The Solution
One example of a use for the web services in a SVM is the Ontapi service that allows api calls to the SVM. I'm not sure offhand if there are other uses but that is one of them.
If you manage everything at the cluster level, not at the SVM level, you can disable SSH/HTTPS access to the data SVM in ONTAP 9.5 and later
