The vSphere HA service is not working on clusters after the vCenter has been upgraded from version 8.x to version 9.0.1.0

Products

• VMware vCenter Server

Issue/Introduction

• The ESXi hosts are still running version 8.x
• vSphere Lifecycle Management (vLCM) rather than vSphere Update Manager (VUM) is being used in the clusters
• In the vSphere UI -
  • When selecting an ESXi host in an affected cluster - this red banner error is observed - 

Desired image for 'domain-xxxxx' is invalid. Save the desired image and Retry.

• • The "Recent Tasks" pane contains an error - 

Remediate HA - A general system error occurred: Installing HA components failed on the cluster: domain-xxxxx

• • Selecting an affected cluster and reviewing the Configure > vSphere Availability page shows - 

vSphere HA is Turned On

• The vSphere HA agent is confirmed to not be running on the ESXi host
• A component vsphere-fdm with version 8.x was specified in the image prior to upgrading the vCenter from version 8.x to version 9.0.1.0

Environment

VCF 9.0.1.0

Cause

• The vmware-fdm VIB is installed automatically on an ESXi host when vSphere HA is enabled on a cluster.
• However, given that a component vsphere-fdm with version 8.x was specified in the image prior to upgrading the vCenter from version 8.x to version 9.0.1.0, the installation of the vsphere-fdm with version 9.x is being blocked.
• This is causing vSphere HA to not function correctly
