Upgrading VCF Automation to version 9.1.x results in a precheck failure with error "Target VSP cluster IP pool CIDR is required"

Products

• VCF Automation

Issue/Introduction

• The upgrade precheck fails in the validate_vsp_cluster_input step.
• The following error appears in the VCF Operations UI:

  An unexpected error occurred in step validate_vsp_cluster_input. Reference Code: 3A6E104C. Detail: com.broadcom.vcf.lcm.sddc.upgrade.plugin.shared.step.io.ValidateVspClusterInputStepInput failed validation. [ConstraintViolationImpl{interpolatedMessage='Target VSP cluster IP pool CIDR is required', propertyPath=targetVspClusterIpPoolCidr, rootBeanClass=class com.broadcom.vcf.lcm.sddc.upgrade.plugin.shared.step.io.ValidateVspClusterInputStepInput, messageTemplate='Target VSP cluster IP pool CIDR is required'}]

  
  

Environment

• VCF Automation 9.x (9.1.0.300 & lower)
• VCF Operations 9.1

Cause

• The VCF Automation upgrade requires a dedicated network CIDR block containing 8 sequential IP addresses. The failure occurs when the configuration provides fewer than the required 8 IPs. 
  
  • Refer Network Details

Resolution

• To resolve the precheck failure, update the network configuration to provide the required IP range:
  1. Log in to the VCF Operations UI.
  2. Navigate to Build > Lifecycle > VCF Instance > Upgrade > VCF Automation.
  3. Click the vertical ellipses and select Configure / Reconfigure.
  4. In the VCF Automation FQDN section (listed as VSP CIDR / IP), enter a CIDR block containing 8 sequential IP addresses.
  5. Click Configure or Save.
  6. Re-run the upgrade prechecks.
     
     
• Note: If the target version of VCFA is 9.1.0.0400 and later, then a dedicated 5 IP CIDP is required.
