KB 2008939 Updating patches on an ESXi host using “esxcli software vib” commands
This video demonstrates how to update patches on an ESXi 5.x/6.x host using “esxcli software vib” commands.
Patches can either be “Installed” or “Updated” on an ESXi host using the “esxcli software vib” commands
Caution: The install method has the possibility of overwriting existing drivers. If you are using third-party ESXi images, VMware recommends using the update method to prevent an unbootable state.
