Verify NetApp clusters with cf-config-check

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic.

A handy tool to use to verify the configuration of both NetApp controllers in a cluster is HA Configuration Checker. This tool will check licenses, network configuration and options on each system to make sure there isn’t a problem during a cluster takeover. Running the script is pretty simple, there is a .cgi and a .exe version.

By default it uses RSH to communicate to the NetApp controllers, personally I like to use SSH which just requires adding the -s into the command. Another thing to be aware of, if you don’t specify the user when using SSH it will use the username you are currently signed in with on the computer it is being run from. In my case that user doesn’t exist on the NetApp controllers so I used the root user.

Pretty helpful, and from this I can see I need to add a FlexClone license and fix my e0 interface or things depending on it may not work in a takeover situation.

NetApp System Manager can also do some basic alerting on issues like these as well, when I removed the FlexClone license from one of my filers you can see the on screen alert.
