Quick Tip - vCenter Server Advanced Settings Reference

by // 1 Comment

Simliar to my ESXi Advanced and Kernel Settings reference, I was recently asked about creating one for vCenter Server to capture all the default out of the box advanced settings.

With some automation in place, I deployed all major releases of the vCenter Server Appliance (VCSA) from 6.7 to 8.0 which is available in this repo: https://github.com/lamw/vc-advanced-settings


For those interested, here is the one-liner PowerCLI code to retrieve all vCenter Server advanced settings:

Get-AdvancedSetting -Entity ($global:DefaultVIServer)

Downgrading new VMware vSphere Foundation (VVF) or VMware Cloud Foundation (VCF) licenses to 7.x

by // 5 Comments

When you access your new VMware vSphere Foundation (VVF) or VMware Cloud Foundation (VCF) license in the Broadcom Support Portal (BSP), it is delivered using the new solution license key type  which can activate multiple components within a VVF or VCF deployment.

By default, VVF and VCF licenses will come entitled for latest vSphere 8.0 Update 2b and VCF 5.1.1 respectively, because those are the minimum versions that support the new solution license key type. With that said, users can also downgrade their existing VVF and VCF licenses to support earlier vSphere 8.x and 7.x releases using the BSP license management system, which was something I had recently learned about and went through the process myself, so here is what it looks like end-to-end.

Note: License downgrade requires both user downgrade permissions in the BSP license management as well as using non-NFR licenses, which can obtained through the BSP self-service "Trials and Beta" or internally for employees. For NFR licenses, downgrade is not available.

Updating handshakeTimeoutMs setting for ESXi 7.x & 8.x using configstorecli

by // 3 Comments

With the introduction of the ESXi Configuration Store back in vSphere 7.0 Update 1, all ESXi configuration changes should be managed using either the configstorecli for an individual ESXi host or leveraging the new vSphere Configuration Profiles (VCP) for scale with vCenter Server.

For certain ESXi hostd configurations such as configuring the handshakeTimeoutUs property, which has changed locations from several locations including /etc/vmware/hostd/config.xml and /etc/vmware/vpxa/vpxa.cfg to now /etc/vmware/rhttpproxy/config.xml in the latest ESXi 8.x release, it can be challenging to figure out the correct configstorecli syntax.

Having spent some time playing with the configstorecli, I was able to quickly help a customer recently who was looking to update the handshakeTimeoutUs property for ESXi 7.x and I wanted to make it easy for folks to find the syntax for both ESXi 7.x and 8.x.
