Determining Build Number and Version for ESXi via vSphere Web Client

June 21, 2017 Jordansphere ESXi

To determine the version and update your ESXi hosts are running, use the following method. It is assumed that vCenter is running in your environment.

 

First of all we need to get build number:

Log in to the vCenter using the web client
Click Hosts and Clusters -> {your vCenter} -> {your Datacenter} -> {your cluster} -> {specific host}.
Under Summary -> Configuration you'll see the ESX/ESXi version. 

 

buildnumber1

 

When we have obtained the build number we need to cross-reference this using VMware KB2143832

A snippet is taken below:
