We are running a standalone VMware 5.5 host server (HP ProLiant) that is not part of a cluster or even a SAN with other hosts. It has a number of patches that need to be applied to it and I'm wondering what the best way to do this is. I can use the Update Manager to stage the patches to the host but then I need to shutdown all the guests in order to put the host in to maintenance mode to actually apply them. Obviously this shuts down the Update Manager. I could vMotion the host off to another server but, as I said, this host isn't a part of a SAN so it would require quite a while to copy everything off and then back again when the updates are done.
Is there a simple way to apply the patches that have been staged once the host is in maintenance mode?
