Here we will see how to upgrade ESXi host from 4.0.0 U1 to 4.1.0 using ESXi tech support mode.
we will need the update bundle which is a zip file.
Also you will have to enable SSH so that you can upload the .zip bundle to ESXi host.
We will use WinSCP and Putty as our tools to connect to ESXi host.
We will need the location of file, so we will highlight the location i.e., /vmfs/volumes/4e4….d42 and right click, which will copy the location to clipboard.
The ESXi host should be in maintenance mode for update to run successfully, and I forgot to put it which gave me the error as shown below.
You will also notice that I have used the “datastore1” in the URL, which also works as it’s the shortcut to the numerical folder that we saw before.
