• Checking the Aria Operations for logs VM, it is deployed successfully.
  
  
• Port connectivity between Aria Suite Lifecycle and Aria Operations for logs on port 22 and 443 works. 

Environment

Aria Operations for logs 8.x

Aria Suite lifecycle 8.x

Cause

• The deployment failure is due to incomplete network connectivity between the Aria Suite Lifecycle VM and the Aria Operations for Logs VM.
  
  
• While basic ports (22 and 443) are open, additional required ports and ICMP protocol are not enabled, leading to communication issues and timeout errors during the post-deployment configuration and validation stages.

Resolution

• Ensure the following network requirements are met between the Aria Suite Lifecycle VM and the Aria Operations for Logs VM as per VMware Aria Suite Lifecycle Product documentation :

  Open the following ports between Aria Suite Lifecycle -> Aria Operations for logs:
  443
  9543
  16520
  22

• Enable ICMP protocol between the two VMs (for ping/heartbeat checks).

• After updating the firewall rules, retry the Aria Operations for Logs installation via Aria Suite Lifecycle UI.
