ESXi configstorecli enhancement in vSphere 8.0 Update 1

03.28.2023 by William Lam // Leave a Comment

The ESXi configstorecli was introduced back in vSphere 7.0 Update 1 and provides access to the ESXi ConfigStore which responsible for centrally managing all configurations for an ESXi host instead of relying on different methods including a variety of configuration files, I highly recommend reviewing this refresher article HERE if you have not heard of the configstorecli before. The ESXi ConfigStore is also the underlying infrastructure that powers the new vSphere Configuration Profile feature which is also part of the vSphere Lifecycle Manager (vLCM) solution.

For those who currently or plan to automate ESXi installations using Kickstart, I wrote an article HERE last year on how to start converting some of your existing automation into using the new ESXi configstorecli, which is another article I recommend folks take a look if you have no already.

One of the challenges that I personally found when using configstorecli was purely figuring out the overall schema for the different components, groups and keys that are available. While I have demonstrated how to traverse the configstore in this blog post HERE, I still found experience less than ideal. I would have liked a bit more of an iterative exploration of the configstore itself and rather than showing the entire schema, I could slowly expect each node as configstore is a stored as a JSON document.

Changing the default HTTP(s) Reverse Proxy Ports on ESXi 8.0

03.22.2023 by William Lam // 7 Comments

The process of changing the default ports for the ESXi Reverse Proxy service has always been pretty straight forward, which I had also shared back in 2015 HERE. While most customers stick with the default configuration (80 for HTTP and 443 for HTTPS), we do have some customers that need to change these ports to meet certain organization security and/or compliance requirements.

Disclaimer: VMware does not officially support modifying the default HTTP/HTTPS ports on an ESXi host.

I recently came across a customer report where the previous method for changing the ESXi Reverse Proxy ports on an 8.0 host no longer worked and the only thing that was shared was that the user could no longer run ESXCLI directly within the ESXi Shell, which I thought was a strange observation.

I deployed the latest ESXi 8.0b as a Nested ESXi VM and I went through the instructions I had outlined in my blog post HERE and changed the HTTPS port from 443 to 4444, which was the setup the user was looking to do and I ran into the exact same issue. At first, I thought maybe we actually no longer support this capability and decided to quickly test by using the remote version of ESXCLI, which allows you to specify a port as part of the connection and it failed with the same error.

UPDATE (07/31/23) - For ESXi 8.0 Update 1 instructions, please refer to this blog post HERE.

NFS Multi-Connections in vSphere 8.0 Update 1

03.20.2023 by William Lam // 12 Comments

The upcoming vSphere 8.0 Update 1 release includes a lot of exciting new features, some of which you can learn about by listening to either The Unexplored Territory and VirtuallySpeaking Podcasts, both of which covered the vSphere 8.0 Update 1 launch announcement. One of the highlighted core storage platform feature is the long awaited NFS capability that will allows users to select and isolate a specific VMKernel interface as shown in the screenshot below.


This actually reminded me of another interesting NFS capability that will also be part of the upcoming vSphere 8.0 Update 1 release, which is for ESXi to support multiple TCP connections for a single NFS v3 volume, also referred to as nconnect for those familiar with this NFS capability.

For those interested in this new NFS capability, it is important to note that this setting will initially only be configurable by using either the vSphere API or ESXCLI directly on an ESXi host.
