VCF SDDC Manager: Identity Internal Server Error

Tue, 25 Mar 2025 13:34:00 -0400

I was recently working on our lab environment at work that runs VCF 5.2.1. This “lab” is the one used in the VMware Livefire classes so it is quite similar to those used in the VMware Explore Hands On Labs. In any case, I had attempted to use Lifecycle Manager to start one of the VMs in the environment and it immediatel failed due to a bad password on vCenter. I did a RETRY on the Request and manually specified the password to use. That immediately went through to success. Since LCM was deployed via VCF’s SDDC Manager, I decided to power that up and attempt to login to it. NOTE: Since this is a lab, we don’t always power on SDDC Manager.

Home Server Build for VMware ESXi and Holodeck

Sat, 30 Nov 2024 17:33:34 +0000

When working with a Holodeck environment, a pretty beefy system is required. While you can get vSAN Ready nodes from vendors like SuperMicro, Dell, HP, etc… I chose to DIY because I really enjoy building systems and wanted something more home-friendly (Read: Less power hungry and quieter.) I’ll do a more in-depth post soon, but for now I’ve had a number of request for my Bill Of Materials (BOM) for my new server.

How to update upstream DNS servers in Holodeck Cloud Builder

Thu, 03 Oct 2024 17:33:34 +0000

When working with a Holodeck environment, the Cloud Builder VM acts as DNS for the lab environment. This handles all dns resolution within the lab itself and forwards all non-lab related DNS queries to upstream DNS servers. These servers are defined VMware Cloud Foundation Lab Constructor (VLC) during the intiial deployment of the lab environment. I needed to do this recently in a lab environment that I moved from one cloud to another, where the originally specified upstream DNS Servers no longer existed. Having invalid upstream DNS Server specified results in extended time to resolution and/or failed requests to resources that reside outside of the Holodeck lab environment.

SDDC Manager Precheck Fails NSX-T Password Expired

Tue, 06 Apr 2021 06:49:39 -0400

I have gotten into the habit of disabling password expiration on linux systems in my lab environments because often times, when dealing with VMware products, these are set to a year or less. Of course forgetting about an expired password can lead to other issues and time troubleshooting. My Validity Check failed due to Password has expired error…

VCF SDDC Manager Not Showing ESXi Bundle

Sun, 04 Apr 2021 13:34:00 -0400

During a recent upgrade of VCF 4.1 to 4.1.0.1 and then on to 4.2, I found myself in a bit of an unsupported situation due to the use of a build that was not part of the VCF 4.2 Bill Of Materials (BOM).

Symptom: SDDC Manager 4.2.0 will not apply the 4.2 update to the ESXi hosts even though the Update 4.2.0.0 bundle for VMware ESXi 7.0 Update 1d has already been downloaded.
