Installing Chelsio driver CD on an ESX 4.x host

This article is taken and modified from Installing the VMware ESX/ESXi 4.x driver CD on an ESX 4.x host (VMware Knowledge Base)

Step 1: Download the Chelsio Drivers for ESX

Download from relevant drivers for your sepcific cards from  Chelsio Download Centre

Step 2: Follow the instruction from VMware

Note: This procedure requires you to place the host in Maintenance Mode, which requires downtime and a reboot to complete installation. Ensure that any virtual machines that need to stay live are migrated, or plan for proper down time if migration is not possible.
  1. Download the driver CD from the vSphere Download Center.
  2. Extract the ISO on your local workstation using an third-party ISO reader (such as WinISO). Alternatively, you can mount the ISO via SSH with the command:

    mkdir /mnt/iso mount -o loop filename.iso /mnt/iso

    Note: Microsoft operating systems after Windows Vista include a built-in ISO reader.

  3. Use the Data Browser in the vSphere Client to upload the ZIP file that was extracted from the ISO to your ESX host.

    Alternatively, you can use a program like WinSCP to upload the file directly to your ESX host. However, you require root privileges to the host to perform the upload.

  4. Log in to the ESX host as root directly from the Service Console or through an SSH client such as Putty.
  5. Place the ESX host in Maintenance Mode from the vSphere Client.
  6. Run this command from the Service Console or your SSH Client to install the bundled package:

    esxupdate –bundle=<name of bundled zip> update

  7. When the package has been installed, reboot the ESX host by typing reboot from the Service Console.

Note: VMware does not endorse or recommend any particular third party utility, nor are the above suggestions meant to be exhaustive.
