Products

• VMware vSphere ESXi

Issue/Introduction

• The following warning message appears in the vSphere client when performing a Cluster Image compliance check against an Image.

The following VIBs on the host are missing from the image and will be removed from the host during remediation: vmware-fdm(8.0.x-<build_number>)

• This warning message has been also be observed on vSphere 7.x and 8.x releases.
• Log snippets from /var/log/vmware/vmware-updatemgr/vum-server/vmware-vum-server.log indicate that VMware Update Manager identified the vmware-fdm VIB in the depot and successfully retrieved the Installed Images task result from the database for a specific cluster. However, the task later reports that the VIB is already present.

Cause

• The warning message can be caused by an orphaned VIB. The vmware-fdm VIB is installed automatically on an ESXi host when vSphere HA is enabled on a cluster.
• The absence of the VIB in the image is not critical. When vSphere HA is enabled, it will automatically install the vmware-fdm VIB after the host exits maintenance mode, ensuring HA functionality is restored.

Resolution

• Proceed with the remediation despite the warning.
• After remediation is complete and the host exits maintenance mode, a reconfigure vSphere HA task should start installing FDM agents on the host.
• If vSphere HA does not automatically reconfigure after the host is brought out of maintenance mode, the reconfiguration can be manually initiated by right-clicking the host in the inventory and click on "Reconfigure for vSphere HA" from the dropdown list.
