VMWare patching without Update Manager

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.

It's quite simple...like this..

You download the Offline Bundle, Upload to ESXi Host, login with SSH, and run esxcli ...

this applies to updates (e.g. 5.1 patches and 5.5 updates)

You patch it like my EE Article, Step by Step instructions with screenshots:-

That's a great write-up, thanks for sharing. I am familiar with this manual method of patching. So, I guess everyone who uses Update Manager has to patch 1 host manually?

Yes, if you use Update Manager, I know more and more clients, that are now dropping off using Update Manager, and writing PowerCLI scripts, that

1. Put Server into Maintenance Mode
2. Upload offline bundles
3. Patch Server
4. Reboot Server
5. Loop and goto next server

and use VMware Orchestra to do this, and tie this in with their Service Management software!
