NPX – Hands-on Exercise (Nutanix Troubleshooting)

The NPX Design Review (NDR) has a 30 minute “Hands-on Exercise” where the NDR Examiners present an issue with a live system that you need to resolve.  This post is an enhancement of the troubleshooting strategy I developed for VCDX and tailored for NPX and Nutanix XCP troubleshooting.

The NDR Examiners are the only ones with access to the live environment, so you need to talk them through what interfaces and screens to access.  They are playing the role of a “customer”, with minimal training and knowledge of the platform, and the NPX candidate is the “expert” driving the resolution.

This post is written with an ESXi and AHV focus, Hyper-V is not covered at all.

NSX-v – Troubleshooting Deep Dive

This is the VMware NSX for vSphere Troubleshooting Deep Dive.  I have aggregated all of the troubleshooting commands, diagrams and explanations that I could find into this post.  Brevity and bullet-points are used to keep the information concise and readable.  If you want more information on a concept use the Additional Resources section at the end.

You do not have access to an NSX-v lab environment and you want to practice these commands? Use HOL-SDC-1425 – VMware NSX Advanced.

This post will be updated with additional information as part of the NSX Link-O-Rama.  If you have content to contribute, post a comment below.

Tech101 – VMware vSphere ESXi

During my VCDX journey, I searched long and hard for a diagram that showed the components of VMware vSphere ESXi in a “big picture” to enhance my understanding.  The closest I could find was in the VMware vSphere: Optimise and Scale training manual (page 66 – Image also here Section 4.1), but it lacked detail.  So I collated all that I could find into this diagram, which is a very handy one to have when troubleshooting vSphere issues.
