Unable to add/move host to empty cluster

Products

• VMware vSphere ESXi

Issue/Introduction

To help users, If they are unable to add/move a non-DPU host into an empty VC cluster or a cluster with disconnected hosts.

Symptoms:

When you first add/move a host with managed DPU to an empty VLCM cluster, it is associated with the DPU vendor of the added/moved host.

Even if you remove all the hosts from this cluster, the association remains. At this point, either a non-DPU host or a DPU-host with a different vendor cannot be added to that cluster. You'd have to create another cluster and add the new hosts.

Environment

VMware vSphere ESXi 8.0

Cause

This happens because the cluster remains associated with the DPU vendor of the host even after all the hosts maybe removed from/disconnected from the cluster.

 

Resolution

The behavior is currently as per design. This KB will be updated, when any backend changes are made

Workaround:

The recommendation is to create a new VC cluster and use it for adding/moving non-DPU hosts.
