Vmware ESX Server

Update Network Drivers on an ESX box
To place the server into maintenance mode
Navigate to the /usr/bin/ directory
Run the following command
vim-cmd /hostsvc/maintenance_mode_enter

Copy the ESX Bundle to a directory on the server, I chose the /sbin/ directory since the esxupdate command also resides there.
Complete this command to install the driver
esxupdate update --bundle <bundle name.zip>

This will complete the driver install, once completed you will want to remove your ESX box from maintenance mode
vim-cmd /hostsvc/maintenance_mode_exit
