Deployment fails when re-using the ILB FQDN when upgrading the VCF Log Management component to 9.1

Products

• VCF Operations

Issue/Introduction

• When re-using the ILB FQDN that is in use by the VCF Log Management 9.0.x cluster, the deployment of the 9.1 component fails
• The VCF Log Management 9.1 UI is online, but shows no data ingested
• The ILB shows unavailable in the 9.0.2 UI, as the IP and FQDN is now in use by the 9.1 component

Environment

VCF Operations 9.x

VCF Operations for Logs 9.x

Cause

There should be a distinct and new IP used for the 9.1 Log Management ILB to avoid this issue.

Resolution

To work around the issue, follow the steps from  Failed component cleanup during VCF 9.1 installation or upgrade to remove the Log Management component.

Afterwards, the Log Management component should be removed from the list under Build -> Lifecycle -> VCF Management -> Components, and you can re-add it using a new IP.
