A walkthrough of using the vSphere Lifecycle Manager (vLCM) image-based process to remediate a vSphere cluster ESXi hosts. In this walkthrough, I am updating a nested vSphere cluster lab environment from ESXi 7.0 Update 1 to ESXi 7.0 Update 2a which is the latest releas of Update 2 for remediation using the vSphere Lifecycle Manager image-based process.
Using the image-based vSphere Lifecycle Manager approach is a great way introduced in vSphere 7.0 that allows using a single image containing not only vSphere components but also OEM hardware firmware, drivers, vendor-addons, and other components in a single image.
This is a one-way process. You can't flip back to using vSphere Update Manager (VUM) for your cluster. You can move ESXi hosts out of the cluster into a VUM-enabled cluster, but the cluster is set to vLCM image updates once you move forward. The image-based process is a newer and more powerful tool in controlling your lifecycle management of vSphere clusters.

Great run through of the process. Is it safe to assume that host profiles are just something that is retained in the background when initially kicking this cluster over to an image managed cluster?

From VMware support, "Images don't modify or replace anything of the hosts profiles"

Great video, thanks. Easy to maintain the hosts, but what about the security and critical updates? To install these i need to increase the the image level every time too?

From VMware support, "In this case yes, you can change or update the image once there is a new patch available."

What happens in VCENTER is running on host that is getting image applied?

As part of the host image process, DRS kicks in and evacuates all VMs from a particular host before it is placed into maintenance mode, including vCenter. Only when a host is fully evacuated and place into maintenance mode does the remediation take place.

@@VirtualizationHowto 1st thanks for the quick reply. But I do not run drs nor HA on the cluster cannot share why.. but in that case will it warn not to run on host with VC or best to move the VC to another host then remediate? Thanks again.

@@dnldnl4880 In this case you can migrate the vCenter to some other cluster, and when you update process is completed you can migrate it back to this cluster. For sure you need to plan some Change in your environment. But that what I can think as of now.

THis is completely wrong approach by Vmware what about if I want to install new ISO because I have HP servers. You dont get that option so this is very dangerous in production
