Issue/Introduction

  • When preparing a host for NSX-T, you see an error message indicating: 
     Credentials for the host need to be specified.
  • When adding the transport node profile and configuring NSX, an error is noted indicating that the IP already exists for that node. 
  • Checking NSX-T manager log /var/log/proton/nsxapi.log, you can see similar messages:
