Issue/Introduction

• Hosts show either of the following Validation Error in NSX-T UI under: System > Fabric > Hosts > NSX Configuration:

9881: Unable to fetch host hardware and network compute information associated with <Host UUID> from inventory. Error is : com.vmware.vim.vmomi.client.exception.SslException: javax.net.ssl.SSLHandshakeException

 

Or

 

9881: Unable to fetch host hardware and network compute information associated with <Host UUID> from inventory. Error is : com.vmware.nsx.management.inventory.access.vc.ComputeManagerNotRegisteredException: Compute manager <Compute manager UUID>  is not registered, it has status as COMPUTE_MANAGER_REGISTRATION_STATUS_REGISTERING

• Compute Manager shows Connection Status Down

Environment

VMware NSX
VMware NSX-T Data Center

Cause

Connection to compute manager was or is down, preventing NSX from synchronizing host information from vCenter.

Resolution

1. Restore connection to the compute manager by re-entering the credentials for vCenter and saving the configuration:
   System > Fabric > Compute Managers > Edit > FQDN or IP Address
   
   
2. Trigger an update for the host individually by selecting it:
   System > Fabric > Hosts > Configure NSX
   
   
3. NSX Configuration status will show success after.
