I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you patch vCenter Server, it will be down, whilst you patch it.

otherwise use vMotion to move off VMs from hosts you need to patch.

If you cannot use the tools which VMware has provided for easy management, you will have to perform it manually.

or turn off the VMs, to patch ESXi and vCenter Server, which means DOWNTIME cannot be avoided.

There are no features that you can use to reduce downtime. You will have to accept downtime, and plan for scheduled outage, whilst you power off the VMs, patch the server, restart the host and restart the VMs.


e.g.

Power the VMs OFF.
