I hope you are already aware that we use VMware Update Manager to update and patch the ESXi hosts, let’s see how to update ESXi without Update Manager. I have published a post previously about performing a patch or upgrade to obtain a specific build number, it might be really useful for this post and I’d encourage you to read my previous post.
First of all, we need to decide the build version or the patch version to be installed and download the offline bundles from the patch repository.
Create a directory in a datastore and upload the downloaded file
Let’s see what are the installed software vib lists with below command, I had most of the later releases of vSphere 6.5 versions. This is just for the verification prior to the upgrade
esxcli software vib list
Install the software vib using below command
esxcli software vib install -d [PATH_TO_THE_VIB_ZIP]
Reboot the ESXi host with “reboot” command
Once it rebooted just check the build version of the host
You can also verify the installed vibs with the same list command latest installation files have been installed
Note: You can also use the below update command to update the same files but complete previous chain of patches and versions should be installed other wise update command will fail. But we used “install” command in the above step will over ride the base files and will complete the installation.
esxcli software vib update -d [PATH_TO_THE_VIB_ZIP]
Here is the sample error for the update command
