Environment

VMware Cloud Foundation 9.x

Cause

The inventory sync process utilizing the 'vcf_brownfield.py' automation script requires valid authentication for the internal 'backup' service account. This failure occurs because the password for the 'backup' entity is either missing, has never been configured, or is in a 'Disconnected' state within the SDDC Manager credential store. Without this synchronized credential, the automation script cannot authenticate management components to complete the sync.

Resolution

To resolve this issue, you must configure or remediate the backup account password through the SDDC Manager UI to synchronize the internal platform database.

1.  Log in to the SDDC Manager UI with administrative privileges.
2.  In the navigation pane, select Security> Password Management
3.  Locate the Backup account in the account list.
4.  Check the status. If it is 'Disconnected' or empty, click the vertical ellipses and select Remediate Password or Update Password
5.  Enter the required password and click Update
6.  Verify the status of the account has changed to Active
7.  Return to the VCF Operations interface and retry the Inventory Sync task.
