An 'Install Log Management' Prompt appears in VCF Operations following VCF 9.1 deployment

Products

• VCF Operations

Issue/Introduction

After deploying VCF 9.1 and installing Log Management, the VCF Operations UI (Operate > Logs) fails to load the logs dashboard. Instead, it presents an "Install Log Management" prompt, even though the underlying logging service is active and running

 

A review of the failed 'update component configurations' task (found under Administration > Control Panel > Management Tasks) confirms a network connectivity issue:

Error Code: LCMVRLICONFIG40119
Error Message: Error occurred while pushing capabilities to VCF Operations for Logs
Exception: java.net.SocketException: Network is unreachable

Environment

VMware Cloud Foundation ( VCF ) Operations 9.1

Cause

The Log Management component is deployed using the subnet's broadcast IP address. This invalid network assignment prevents proper communication between VCF components, resulting in the "Network is unreachable" exception during the capability push process. An nslookup for the Log Management FQDN confirms that both forward and reverse lookups resolve to the subnet's broadcast IP address.

Resolution

To resolve this issue, the corrupted deployment must be removed and redeployed with a valid IP address.

1. Remove the corrupted Log Management deployment from the Fleet Lifecycle inventory by following the instructions outlined in Broadcom KB 441333.

2. Update the A and PTR records on the authoritative DNS server to reflect a new, valid IP address assigned from the VCF Services runtime network range.
   
   Note: The FQDN must be unique, must not point to any IP addresses already assigned to VCF services runtime nodes, and must be different than the existing one. Capital letters must not be used in the FQDN.

3. Validate that both forward and reverse DNS lookups resolve correctly for the FQDN to the newly assigned IP address.

4. Redeploy the Log Management component according to the official VMware Cloud Foundation "Deploy Log Management" product documentation.
