When configuring a Load Balancer pool members with object identifier, you experience these symptoms:
VMware NSX for vSphere 6.3.x
This issue occurs because VMware Tools is not installed on the pool member virtual machine.
Object Identifier depends on VMware Tools. If VMware Tools is not installed on the pool member virtual machine, the Object Identifier fails.
This issue is resolved in VMware NSX for vSphere 6.4.0.
Workaround:
Ensure that VMware Tools is installed on the virtual machines where the pool members are located.
