Analysis

1. SG appliance has four (4) partitions.
   • The first partition is a system partition which installs Centos operation system and system file.
   • The second partition is a data partition which stores SG appliance data, such as service pattern, debug log.
   • The third partition is an image partition which stores all SG mini service image, such as FPS, SPS, CTD, TPI, ADS, LAU and so on,
   • The last partition is a hide(backup) partition, when a new SG appliance firmware is downloaded it will be installed with the new firmware in the last partition.

Solution

• We will release a build to fix this issue in Sep, 2023.
• You can modify the grub configuration to start the service gateway when you power on it, be careful when doing this, as this may disrupt the system.
