During a VMware Cloud Foundation (VCF) upgrade to version 9.1, the deployment of VCF Management Services fails during the validation phase.
Validation failed with resultStatus FAILED. Validation checks (1): Validate VCF Instance Cloud Proxy Registration Remediation: Verify VCF Instance Cloud Proxy Registration is properly configured.The SDDC log shows the following exception: /var/log/vmware/vcf/domainmanager/domainmanager.logs
{
"errorCode": "BROWNFIELD_VCF_INSTANCE_CLOUD_PROXY_REGISTRATION_VALIDATION.error",
"message": "VCF Instance Cloud Proxy Registration validation failed",
"remediationMessage": "Verify VCF Instance Cloud Proxy Registration is properly configured"
}
This issue occurs because the VCF instance integrations in VCF Operations have not been transitioned to a Cloud Proxy. In VCF 9.1, the management stack requires the VCF instance adapter (vCenter Server Endpoint) to point to a healthy Cloud Proxy or a designated Cloud Proxy collector group rather than a local collector to pass registration validation.
To resolve the validation failure, manually update the VCF integrations in VCF Operations to utilize the Cloud Proxy collector group.
