The Bottom Line

Install VUM and integrate it with the vSphere Client. vSphere Update Manager (VUM) is installed from the VMware vCenter installation media and requires that vCenter Server has already been installed. Like vCenter Server, VUM requires the use of a backend database server. Finally, you must install a plug-in into the vSphere Client in order to access, manage, or configure VUM.

Master It You have VUM installed, and you've configured it from the vSphere Client on your laptop. One of the other administrators on your team is saying that she can't access or configure VUM and that there must be something wrong with the installation. What is the most likely cause of the problem?

Determine which ESX/ESXi hosts or VMs need to be patched or upgraded. Baselines are the “measuring sticks” whereby VUM knows whether an ESX/ESXi host or VM instance is up to date. VUM compares the ESX/ESXi hosts or guest OSes to the baselines to determine whether they need to be patched and, if so, what patches need to be applied. VUM also uses baselines to determine which ESX/ESXi hosts need to be upgraded to the latest version or which VMs need to have their VM hardware upgraded. VUM comes with some predefined baselines and allows administrators to create additional baselines specific to their environments. Baselines can be fixed —the contents remain constant —or they can be dynamic, where the contents of the baseline change over time. Baseline groups allow administrators to combine baselines and apply them together.
