Attempting to create a new deployment destination in vCommander™, you find you are unable to select a cluster as the target.
The Next button only appears when you have selected one of the cluster’s hosts.
This occurs when the cluster is not configured to use vSphere DRS which
provides deployments with the logic required to choose a host onto
which the service will be deployed. Otherwise, the host must be
specified in the vCommander™ deployment destination explicitly.
You can confirm whether or not vSphere DRS is enabled by viewing the
cluster features page of the cluster settings in the vSphere client.
Note that DRS must be set to Partially Automated or Fully Automated so that the placement logic exists to choose a host on the cluster. If DRS is set to Manual no such logic exists and you will not be able to select the cluster as a target.
