Expand the Disk Size for a virtual Airwall Gateway

The v3.0 firmware for Airwall Gateways may require more disk space than you currently have allocated on your virtual machines. If so, you get an error message Under Health data > Reporting about the disk being too small when you try to update it:


Update error in the Airwall Gateway health reporting tab indicating the disk is too small

Important: If you are updating paired High Availability (HA) Airwall Gateways, expand and update the active first, then the standby.

Before you begin

If you have checkpoints for the virtual machines you’re expanding, you first need to either delete the checkpoints or clone the virtual machine. For more details on how, see the documentation for your virtual machine software.
