Easy Scale fails to add compute node when NSX is enabled on HCI Cluster in vCenter.

Applies to

• HCI 1.9
• HCI 1.8
• HCI 1.7
• HCI 1.6
• NSX enabled on the Cluster where Compute nodes reside.

Description

• When attempting to add a net-new or replacement compute node into an HCI cluster, the Easy Scale function of the NetApp Deployment Engine (NDE) fails to add the node and generates the error below:

Your network could not be detected. Ensure that this is the datacenter and cluster associated with your vCenter instance.
