I was doing an in-place vCenter upgrade from vCenter 8 to vCenter 9 using the VCSA 9 ISO. Stage 1 (deploying the new appliance) completed fine, but Stage 2 prechecks failed with a generic “internal error” in the installer UI. In this post I’ll show how I troubleshooted and solved it.
Deploying vCenter Server (VCSA) using the CLI installer is fast, repeatable, and ideal for lab environments or scripted deployments. In this post, I’ll demonstrate how to deploy a brand new vCenter server using the CLI installer. While this post focuses on CLI deployment from macOS, the process for Linux and Windows is very similar.
Due to popular demand, I have updated the vCenter SSL Installation script with some significant enhancements. (Once again Credit to Ryan Bolger – https://github.com/rmbolger for the Posh-ACME module). This update now checks for prerequisites and installs them. In addition, it now supports vSphere 7 and vSphere 8. The latest version of Install-vCenterSSL.ps1, generates certificates and then…
If you are hitting this error while trying to launch the VCSA Installer, “Installer” is damaged and can’t be opened. You should eject the disk image. This is most likely just macOS Security Gatekeeper getting in the way, don’t worry the fix is simple! Note: This issue also affects the CLI Installer too. To have…
This quick post demonstrates how to export the Machine SSL embedded Private key from your vCenter Server Appliance (VCSA). If you replaced the default Machine SSL certificate on your vCenter where the CSR was generated from the vCenter Server, the private key would be embedded in the vCenter Appliance certificate store. If you need to…
During the vCenter Server 8.0 upgrade, I was faced with the following Pre-upgrade check error and wasn’t able to continue the upgrade. As of vCenter Server 8.0, certificates with SHA-1 signature algorithms are no longer supported and must be removed or replaced with a certificate that uses SHA-2 signature algorithm. In this post, I’ll show…
Customising ESXi image profiles is helpful when you need to add custom drivers to your ESXi installation image. I will demonstrate in this post, how to customise ESXi image profiles using the built-in Image Builder service on vCenter 7. I usually use Powershell to build customised ESXi images; however, non-windows users might find this handy…
I recently came across this useful app, Alertzy.app. It’s a service that allows you to send and receive real-time alerts as push notifications on your iOS and Android device. I was impressed with how simple it was to set up and use, and it’s free for up to 100 notifications per day. I figured this could…
