com.vmware.evo.sddc.common.core.error.InternalServerErrorException: Required product HCX not found in BOM for version check
Caused by: com.vmware.evo.sddc.lcm.model.error.LcmException: "Could not find VMware product version in manifest bom for release: 5.2.4.0 and type: HCX"
VMware Cloud Foundation 9.1
The upgrade sequences API fails during a straddle-state component upgrade (such as ESXi 8.x to 8.y) if the environment contains VMware HCX and the bill of materials (BOM) validation cannot map the product version within the specific release manifest.
To bypass the manifest dependency block, active HCX components and dependencies must be decommissioned before retrying the host lifecycle operations:
Finalize Migrations: Ensure all active virtual machine migrations are completely finalized, stabilized, or canceled.
Remove Network Extensions: Unstretch and remove any active or extended network configurations within HCX.
Delete Service Meshes: Delete any active service mesh configurations deployed across the sites.
Uninstall HCX: Once active dependencies are removed, proceed with the uninstallation of the HCX appliance to clear the lifecycle management block.
Retry Upgrade: Log back into the SDDC Manager UI and re-initiate the ESXi host upgrade plan.
