We received our 3 node Nutanix cluster last week. I did contract for professional services to help with the install, but given that professional services getting scheduled is still a week out I decided it was better if I started the process myself. I figured how difficult could it be to build out a Nutanix Cluster using AHV for the hypervisor. Really how difficult can it be to learn a new platform and everything that goes along with it. This is the list of things that I learned while doing the install myself and working through the problems that I encountered.
It helps to validate the port configuration on the back of the unit, the only support case I needed was to find out what ports were data, which were data/ipmi, and which were ipmi only. That wasn’t information that I was able to find on my own easily. So I opened a ticket with support and they gave me the exact information that I needed.
Make sure all of the ports are correctly configured on the network. Don’t just follow the QuickStart guide, because when it says you only need a data port in a dumb switch that isn’t necessarily correct or at least wasn’t in my case. I lost a few hours to the networking side, just figuring out that I needed the final trunked network connection to get everything talking correctly.
Put the IPMI onto it’s own network so that it is separate, and should be on a completely private network. In my case I hooked it up to our Opengear Serial Console with a 24 port switch that is a separate admin network.
Keep the Hypervisor and CVM on the same network and it will make life easier
Make sure to run the health check a few times and correct everything it says, just so things aren’t annoying. I had some that were info and just wanted them all cleaned up.
Realize that it will take time for all of the health alerts to cycle out of the console. So sometimes just waiting a day makes all the difference when trying to clear up the alerts. So if the health check comes back fine on the command line or console, it just might need some time.
Create a new local admin to resolve the annoying API alert that keeps popping up and that they don’t have you do anything with during the quick start install.
I’ll keep updating as I go and find new things, just as reminder for myself for the next install that we will most likely be doing in our Cold or Distribution Center.
Thanks to sharing your Nutanix deployment experience.
I found your blog on Google. good Job!
