When managing a VMware Cloud Foundation (VCF) 9.x and 5.x environment, you may experience the following:
VMware Cloud Foundation 5.x
VMware Cloud Foundation 9.x
In VCF 9.x and 5.x and , Vendor Add-on does not automatically apply to the ESXi hosts. Even if hosts are compliant with the standard VCF 9.x and 5.x BOM, the system requires the cluster Image to be manually updated to include the new Vendor Add-on. Because the base ESXi version remains the same, SDDC Manager recognizes the environment as being on the latest "VCF version" and does not trigger the upgrade workflow.
The upgrade option requires the manual addition of the Vendor Add-on to the Cluster Image within vCenter.
Step 1: Access the Cluster Image
Step 2: Update the Image Configuration
Step 3: Check Compliance and Apply
