Template Creation Section

Issue 1: A specific vCenter Server is not present in the drop-down list to extract the Configuration Settings during Step 2 of Create Config Template

Possible causes:

• vCenter Server is not in the supported version, should be at least 80U3
• vCenter Server is not registered to a Cloud Proxy.
  • Please reference Configuring Cloud Proxies in VMware Aria Operations.
• vCenter Server is not reachable from the Cloud Proxy.
  • Please reference Cloud Proxy Troubleshooting.

 

Issue 2: Error occurred while retrieving Configuration Settings from selected VC

Possible causes: 

• vCenter Server is not reachable from the Cloud Proxy. Please reference Cloud Proxy Troubleshooting
• Config Module is not running (See Appendix on how to check if Config Module is running)

Remediation:

• Contact Broadcom Support if the Adapter is unable to recover from the ERROR state or the Config Module is not running.
  
  

Issue 3: Unable to view any Configuration Settings from the selected VC in the Config Template Preview pane

Possible cause:

• vCenter Server is registered with an account that does not have ‘Administrator’ privileges in vCenter.
  • Please check all prerequisites as described in the Configuring Cloud Proxies in VMware Aria Operations - Prerequisites

 

Drift Check Section

Issue 1: Drift Check Failed with error: "An internal error has occurred" 

Possible Causes :

• vCenter Server is not reachable from Cloud Proxy.
  • Please reference Cloud Proxy Troubleshooting.
• Config Module service is not running. (See Appendix on how to check if Config Module is running)

Remediation :

Issue 2: The Drift Check has been in progress for a long time.

NOTE: The user will be notified in the UI client with the message: "Drift check in progress..."

Possible Causes :

• Multiple vCenter Server drifts may be triggered at the same time. The check will be completed only when all the vCenter drifts are completed.
• The system failed to update the task status due to connectivity failure with Cloud Proxy.

Remediation :

• Retry Drift Check with a lesser number of VCs selected once the currently running task fails after the configured timeout of one hour.
