Over the weekend, I had to re-deploy a portion of my VCF 9.1 Fleet, including VCF Operations, VCF Management Services, VCF License Server, SDDC Manager and VCF Automation, due to some workflows I was testing.
Luckily, my core SDDC components vCenter, NSX and vSAN was not touched and I could simply re-use those components by running the VCF Installer Import/Converge process to quickly rebuild my VCF 9.1 Fleet!
Prior to deleting VCF Operations, I had VCF Single Sign-On (SSO) configured and I wanted to make sure the core SDDC components were properly cleaned up. I successfully ran through the VCF SSO unjoin operation for all components and cleaned up the vCenter Server Advanced Setting (config.OPERATIONS.vcf.sso.ops.cluster.id), which was required with VCF 9.0.x before you could add it to a new VCF SSO configuration.
After my VCF 9.1 Fleet was re-deployed, the first thing I wanted to go setup was VCF SSO and I noticed the configuration button was grayed out and it had the following message:
No VCF instance available due to one of the following: no existing instance, invalid license, version below 9.0, setup in progress, already configured via another Operations or running ELM.
