Issue/Introduction

The Edge SWG (ProxySG) or Advanced Secure Gateway (ASG) is failing to boot.

When connected to the serial console and booting up, you see the AMIBIOS screen go by then it gets stuck on the next screen with an output like Booting from SATA PS: ATP IG SlimSATA Part1.

Cause

The primary boot device is connected, but there is an issue with the data on the disk.

Resolution

Boot from the Secondary SSD (SS) by:

1. Reboot the appliance
2. On the AMIBIOS screen (the first screen that appears in the serial console), press CTRL+S
3. The next screen should show Booting from SATA SS: ATP IG SlimSATA Part1 [Note: it is now SS instead of Primary SSD (PS)] and follow with a list of images to boot from.

When the appliance boots from SS, there is a mirroring process done to PS. Thus, the data will be corrected on PS and a reboot will successfully boot from it now.
