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; it should be at least 8.0 U3.
• 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 the selected VC.

Possible causes:

• vCenter Server is not reachable from the Cloud Proxy. Please reference Cloud Proxy Troubleshooting.
• Config Module is not running (See 'How to check whether the Config Module service is in running mode' 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.
  • Solution: The user with which the vCenter server is registered with the cloud proxy must be part of the Administrators group in vCenter.

 

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:

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

 

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 the Cloud Proxy.

Remediation:

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

 

Overview Section

Issue: Several vCenter Servers have drift status as UNAVAILABLE.

Possible cause:
The vCenter Server drift status can be UNAVAILABLE for the reasons listed below:

• Drift check is in progress (refer to Drift Check Progress issue above).
• Drift check errored (refer to Drift Check Section above).
• Drift check was never performed.

If nothing from the remediations or information above helps to resolve your issue, please Contact Broadcom Support.
