How to revert an ESXi host to a previous version using DCUI

This video demonstrates how to revert an ESXi host to a previous version using the Direct User Console Interface (DCUI).

VMware recommends that you back up the configuration data before proceeding with any changes.

Reverting an ESXi host is only available if the host was updated using one of the following methods:

  • VIB installation or removal
  • Profile installation or removal
  • ESXi host updated using VMware Update Manager
  • ESXi host updated from a ISO

Updating patches on an ESXi host using “esxcli software vib” commands

This video demonstrates how to update patches on an ESXi 5.x/6.x host using “esxcli software vib” commands. Patches can either be installed or updated on an ESXi host using esxcli vib commands.

Caution: The install method has the possibility of overwriting existing drivers. If you are using third-party ESXi images, VMware recommends using the update method to prevent an unbootable state.

Patches for VMware products can be downloaded from the following location

How to install vSphere 6 ESXi using the Interactive Installer

Interactive installations are recommended for small deployments of four or less hosts. Installation using this method involves booting from the ESXi 6.0 installation media by inserting the media in to the host and following the prompts from the installation wizard to choose a destination disk in the host and begin the installation. Our video today demonstrates how to install vSphere 6 ESXi using the Interactive Installer.

The ESXi installation media can be connected to the host in a few different ways:

  • Inserting the CD/DVD in to the DVD-ROM drive in the server
  • Plugging in a bootable USB device
  • Mounting an ISO remotely

When instructed to begin, the installer reformats and partitions the target disk and installs the ESXi boot image. If you have not installed ESXi on the target disk previously, all data located on the drive is overwritten, including hardware vendor partitions, operating system partitions, and associated data.

Note: The formatting and partitioning done by the ESXi installer is permanent and overwrites existing data. To ensure that you do not lose any data, migrate any important data from the host to another machine before you install ESXi. If you are installing ESXi on a disk that contains an installation of ESXi/ESX or a VMFS datastore, you are presented with upgrade options.
