    AS most of you know, the upgrade proces with Nutanix is almost one-click. It is very easy to start, but you have to wait quite some time to see it finished. Every now and then the wait takes too long, and you get a little impatient. I had that today, so I decided to check…

    Nutanix – Destroy cluster using Prism Central

    Using LACP with Nutanix AHV

    Change Gateway on Nutanix AHV cluster

    Hopefully you will never need the information in this post. Lately, a wrong gateway was entered during the initial setup of a Nutanix cluster. Because the cluster was configured connected to a standalone switch, the typo was found when the cluster was already connected to the customers production network and was unreachable… Luckily you can…
