Testing reconnection of an ESXi to vCenter Server

To diagnose communication problems between an ESXi host and vCenter Server, VMware recommends that you disconnect the ESXi  host and then reconnect it.
 
To test reconnection of an ESXi  host to vCenter Server:
 
  1. Login to the vSphere Client.

    Note: If your ESXi host is already disconnected proceed to step 5.
     
  2. Right click on the ESXi  host in the Inventory.
  3. Click Disconnect.

    Note:     A disconnect host task appears in the recent tasks pane.
     
  4. Wait until the task status changes to complete.
  5. Right click on the ESXi from the Inventory.
  6. Click Connect.

    Note: A reconnect host task appears in the recent tasks pane.
     
Wait until the task status changes to complete.



If the host status remains unchanged, restart the host management agents.

  1. SSH to the ESXi host via root
  2. Restart the 2 below management agents
/etc/init.d/hostd restart
/etc/init.d/vpxa restart
