Download and Install Patches for ESXi

Just a quick guide on how to download and install patches for VMware ESXi (free version).

Go to the VMware Patch Portal, select the product and version to view and download available patches:

In this example, I'm going from ESXi 5.5.0 build 1474528 to 5.5.0 build 1623387 (Update 1).

When the download is complete, upload the entire zip file to a datastore on your ESXi host.


SSH to your host.

Enter maintenance mode.

# vim-cmd hostsvc/maintenance_mode_enter

Verify the patch file.

# cd /vmfs/volumes/datastore1/Patches/
/vmfs/volumes/52ed3575-a67d75d2-17ab-001cc4d54e5f/Patches # ls         

Run the update.

# esxcli software vib update -d /vmfs/volumes/datastore1/Patches/


# esxcli software vib list


# reboot

Exit maintenance mode.

# vim-cmd hostsvc/maintenance_mode_exit
