I have 3 ESXi hosts running 5.1. One of the VM's on host A is a Windows 2008 Server that is running vCenter Server with Update Manager. I am using Update Manager to patch host B and host C.
How do I update/patch host A if I have to turn off all of the VM's and enter maintenance mode? My vCenter Server is now powered off. I am familiar with downloading the zip files and patching manually, but is this how I have to patch host A when I have Update Manager??
Thanks for any help.
