VMware makes periodic updates to the ESXi Installable version you can download. This page was created to help track and locate those.

Use these numbers to determine when a system was patched last and to make sure the VMware Infrastructure Client is the right one.

Best Practice:

ESXi: Run the VMware Infrastructure Update tool from a windows management station with the VMware Infrastructure Client every month.

ESX: Use vCenter Update Manager to scan and remediate ESX hosts when new security patches are available.

How to Check the Version Numbers:

  1. Download the VMware Infrastructure Client from the Web User Interface.
    For example: https://ESX-HOST-IP-ADDRESS/client/VMware-viclient.exe
  2. Start the VMware Infrastructure Client
  3. Click the Help Menu
  4. Select “About”
  5. Note the Version and Build for both the Client and Server.
  6. Compare to list below to ensure they are at same release.
  7. If you update the Server you should connect to the Web User Interface and download the latest VMware Infrastructure Client.

The typical way to apply patches to ESXi hosts is through the VMware Update Manager. For details, see the VMware Update Manager Administration Guide.

ESXi hosts can also be updated by downloading the most recent “O” (offline) patch bundle from http://support.vmware.com/selfsupport/download/ and installing the bundle using VMware Infrastructure Update or by using the vihostupdate command through the Remote Command Line Interface (RCLI). For details, see the ESX Server 3i Configuration Guide and the ESX Server 3i Embedded Setup Guide (Chapter 10, Maintaining ESX Server 3i and the VI Client) or the ESX Server 3i Installable Setup Guide (Chapter 11, Maintaining ESX Server 3i and the VI Client).

Note: ESXi hosts do not reboot automatically when you patch with the offline bundle.
