Changing a host from HMC managed to NovaLink managed

Edit online

PowerVM® NovaLink enables highly scalable cloud management and deployment for critical enterprise workloads. You can use NovaLink to manage virtualization while still using the Hardware Management Console (HMC) to manage your firmware and hardware, or you can use NovaLink independently of HMC. In your PowerVC environment, there can be hosts that are managed by NovaLink and hosts that are managed by HMC.
