Cannot update my virtual Airwall Gateway from v1.12 to v2.0

If the Airwall Gateway does not have enough disk space, the firmware update fails with no indication it has failed.

In v2.0.0, the Airwall Gateway Virtual Disk image was resized to 138.5MB. Previously-deployed Airwall Gateways (from any launch prior to 2.0) have a virtual image size of 55MB.

Affected Versions
VMware ESXi and Hyper-V Airwall Gateways running v1.12.x

Solution

Resize the virtual disk on your Airwall Gateway to at least 150MB and try the update again. The following links provide instructions for resizing the the virtual disk for the virtual machine running the Airwall Gateway:

  1. Power off the virtual machine (VM).
  2. Resize the virtual disk using the guidance contained in the links at the top of this page.
    Note: You must resize the virtual disk while it's offline.
  3. Power on the VM and perform the firmware update.
