ESXi upgrade from SDDC UI cannot proceed with error 'Upgrade is requested for cluster <clusterID> which is in failed state'

Products

• VMware SDDC Manager

Issue/Introduction

The upgrade of the hosts cannot proceed as SDDC sees the cluster as being in a failed state:

Environment

VCF 5.x

Cause

This issue can be caused by prior upgrade failures on hosts in the referenced cluster.

The error in the UI can be misleading because often the cluster itself is in an 'ACTIVE' state but a host or hosts in that cluster are in an error state.

Resolution

• In the SDDC UI navigate to Workload Domain --> Hosts and identify which host or hosts are in an ERROR state.
• In vCenter confirm if these hosts are having issues. If so resolve any issues identified.
• Once all hosts are confirmed as stable it will be necessary to toggle the status of these hosts to ACTIVE in the SDDC database.
• Please contact Broadcom Support for assistance on this procedure.
