When attempting to deploy products through Aria Suite Lifecycle, I/O errors are encountered with Task Cancelled by User seen in vCenter

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

Symptoms

When attempting to deploy a VMware Aria Suite 8.x product through VMware Aria Suite Lifecycle, the OVF deployment task fails abruptly. You will see different errors depending on where you look:

• In vCenter, the task Status reports as "The task was canceled by a user."
• In the Aria Suite Lifecycle UI, the request fails with a generic I/O error:

  LCMVSPHERECONFIG1000016 An exception was given to I/O when performing the operation.

• In the Aria Suite Lifecycle log file (/var/log/vrlcm/vmware_vrslcm.log), a "Connection timed out" error is found, which indicates the root cause of the failure:

  ERROR vrlcm[####] [pool-3-thread-17] [c.v.v.l.p.c.v.t.DeployOvfTask]  -- IO Exception occured while uploading files to vCenters datastore. Error : {} 
  java.net.ConnectException: Connection timed out (Connection timed out)

Environment

VMware Aria Suite Lifecycle 8.x

VMware vSphere 7.x / 8.x

Cause

This issue is primarily caused by misconfigurations in networking or storage. Specifically DNS related issues or required ports not being opened.

Resolution

1. Verify that all network prerequisites are met as outlined in the System Requirements documentation. Pay close attention to:
   • DNS Resolution: Ensure forward and reverse DNS is working correctly for all components, including Aria Suite Lifecycle, the products being deployed, ESXi hosts, and vCenter.
   • Network Ports: Confirm that all required firewall ports are open between Aria Suite Lifecycle and the target vSphere infrastructure.
2. As a troubleshooting step, reattempt the deployment, targeting a different vSphere cluster, datastore, or network port group to help isolate potential infrastructure-specific issues.
