When I install new ESX4 Hosts, most of the time I patch them manually, have the patches with me on a USB Stick. This saves me lot of time.
- Use following cli command on ESX4 to put the host into maintenance mode: vimsh -n -e /hostsvc/maintenance_mode_enter
- Put the Patch Archive e.g. ESX400-200909001.zip to the ESX4 Host
- Run following cli to manually install the Patch Bundle: esxupdate –bundle ESX400-200909001.zip update
- Reboot the Host: reboot
- Exit maintenance mode: vimsh -n -e /hostsvc/maintenance_mode_exit
