Issue/Introduction
SDDC Manager UI displays the error: "Failed to fetch NSX information".
SDDC Manager API calls targeting the NSX-T manager fail.
SDDC Manager generates "Disconnected" alerts regarding the NSX-T manager.
Environment
VMware Cloud Foundation (VCF) 5.2
SDDC Manager
NSX-T Data Center
Cause
An NSX-T Manager associated with the environment was decommissioned out-of-band (outside of native SDDC Manager workflows). Consequently, the SDDC Manager was not detached from the NSX-T manager during the decommissioning process.
The SDDC Manager's PostgreSQL platform database is out of sync and retains an orphaned record of the decommissioned NSX-T cluster.
The SDDC Manager services continuously attempt to manage the lifecycle and passwords of the non-existent appliance, triggering the disconnected alerts and UI/API errors.
Resolution
To resolve this issue, the orphaned NSX-T entry must be manually removed from the SDDC Manager database.
