SDDC manager host pre-checks fail during an EMM dry run validation due to a VM fault.

Products

• VMware vSphere Kubernetes Service

Issue/Introduction

An SDDC manager ESXi host update pre-check fails with the following "enter maintenance mode" error message:

• Upgrade preCheck is failing with error "<host-FQDN> Checks for VM faults while performing EMM dry run for host <host-FQDN> ERROR A VM faults were found while performing a dry run enter in maintenance mode validation High: Do not perform upgrade without addressing this issue."

Environment

• VCF 9.x

Cause

The vSphere cluster that the ESXi host is a member of has a Supervisor environment deployed on it, and the ESXi host listed in the error message is seen in a "NotReady" status within the Supervisor cluster.

Resolution

• Place the affected ESXi host into maintenance mode
• If the affected ESXi host is not automatically removed from the Supervisor cluster, run the following command on the Supervisor to remove the ESXi node:
  • kubectl delete node <host-FQDN>
  • Take the affected ESXi host out of maintenance mode, and run the "kubectl get nodes" command to see if the host is added back into the Supervisor cluster, and if it is in a Ready status.

Additional Information

If the ESXi host does not get added back into the Supervisor cluster after taking it out of maintenance mode, or the Supervisor still reports the host in a "NotReady" status, please contact Broadcom Support for additional troubleshooting.
