Unable to install NSX on re-imaged ESXi Host

Products

• VMware NSX
• VCF Operations

Issue/Introduction

• ESXi Host has just been re-imaged and NSX needs to be re-installed
• Old ESXi object is hung in NSX from a previous task of adding a host to a cluster that failed
• Stale ESXi host shows the configuration state as "Host Disconnected" in NSX UI
• Removing the ESXi host from the cluster shows Host under the "Other Nodes" tab
• Moving the ESXi host back into the cluster shows the configuration state as "Orphaned" in NSX UI
• The API call DELETE https://<NSX Mgr IP>/policy/api/v1/infra/sites/default/enforcement-points/default/host-transport-nodes/<NSX Transportnode ID>?force=true&unprepare_host=false has been used to clean up the stale host entry in NSX
• Moving the ESXi host back into the cluster shows host as "Not Configured" and does not trigger the installation of NSX on the host
• Unable to use the "Configure NSX" option because the cluster is a VCP enabled cluster and all options are greyed out
• In vSphere client, the ESXi is out of compliance with error message - "Desired configuration failed validation on host. Check compliance is skipped"

Environment

VCF 9.0.1 

Cause

• The ESXi host is not in compliance with desired configuration
• The ESXi host was configured with a "Referenced host" from a different site

Resolution

• The new host needs be in compliance with desired configuration 
• Ensure that the "Referenced host" used for configuring the host belongs to the same site as the new host 
• If host is not in compliance, follow the steps below to import configuration 
  • Import from Host > Select reference host > Import
  • 
  • 
  • Check Compliance again and Apply the configuration

 

NOTE: NSX installation should begin automatically on the ESXi host once it is in compliance with the desired configuration
