The following VIBs on the host are missing from the image and will be removed from the host during remediation: vmware-fdm

I’ve seen a few people being confused about a message which is shown when upgrading ESXi. The message is: The following VIBs on the host are missing from the image and will be removed from the host during remediation: vmware-fdm(version number + build number). Now this happens when you use vLCM (Lifecycle Manager) to upgrade from one version of ESXi to the next. The reason for it is simple, the vSphere HA VIB (vmware-fdm) is never included in the image.

If it is not included, how do the hosts get the VIB? The VIB is pushed by vCenter Server to the hosts when required! (When you enable HA for instance on a cluster.) This also is the case after an upgrade. After the VIB is removed it will simply be replaced by the latest version of it by vCenter Server. So no need to be worried, HA will work perfectly fine after the upgrade!

Upgrading to vSphere 7.0b and not sure what the 7.0bs image is?

Are you upgrading to vSphere 7.0b and not sure what the difference is between 7.0b and 7.0bs? Well that isn’t strange, I had the same problem. I asked around internally and after a bunch of email exchanges, I was informed that the vSphere 7.0bs image is “security updates only”. After I brought it up the team has since quickly modified the release notes to include the following:

Name and Version Release Date Category Detail
ESXi 7.0b – 16324942 06/16/2020 Enhancement Security and Bugfix image
ESXi 7.0bs – 16321839 06/16/2020 Enhancement Security only image

Like I said on twitter if you didn’t know, now you know!
