Aria Automation 8.18.1 Upgrade Precheck Fails Due to Source IPs in Target Network

Products

• VCF Automation

Issue/Introduction

When attempting to upgrade from VMware Aria Automation (AA) 8.18.1 to VCF Automation (VCFA) 9.1, the upgrade precheck fails. The system displays the following error messages indicating a network topology check failure:

• Check: All source system nodes are on the same target network

• Message: One or more source system node IP addresses are outside the configured target network subnet. [com.broadcom.vcfa.upgrade.topology.check.test-topology-06a-source-ips-in-target-network]

Environment

VMware VCF Automation 9.1

Cause

This issue is caused by a mismatch between the target network CIDR (VCF Services Runtime nodes for VCF Automation) and the VCFA Network configuration.

Resolution

• Connect to the Services Runtime control plane via SSH using the vmware-system-user account.

• Switch to the root user environment by executing the command: sudo su -.

• Verify the upgrade workflow status by checking the pods in the platform namespace:

  kubectl get pods -n vmsp-platform

• Check the pods within the prelude namespace to locate the failure:

  kubectl get pods -n prelude

• Identify the pod NAME that currently displays an Error in the STATUS column (e.g., vcfa-precheck-upgrade-80-topology-#####-execute-script-#######).

  • NAME                                                                                                         READY                            STATUS     RESTARTS       AGE
    vcfa-precheck-upgrade-80-topology-#####-execute-script-#######     0/2                                  Error         0                     10m

• Review the logs for the identified pod by executing:

  kubectl logs <pod_name> -n prelude

• Validate that the logs output the following precheck failure indicating the IP addresses are not in the target network:

  YYYY-MM-DD HH:MM:SS [INFO] Validating platform VIPs are within target network

  YYYY-MM-DD HH:MM:SS [ERROR] PRECHECK FAILED: ipv4Pool IPs not in target network:

  <REDACTED_IP> <REDACTED_IP> <REDACTED_IP> <REDACTED_IP> <REDACTED_IP>. Network: <REDACTED_IP>/##

• To resolve this, correct the invalid network information from the VCF Operations user interface.

• Navigate to VCF Operations Lifecycle -> Build -> Lifecycle -> VCF Management -> Upgrade.

• Click the three dots (...) menu and select Reconfigure.

  • 

• Under the Parameters section, enter the strictly correct CIDR value into the VCF services runtime nodes CIDR field.
