Restarting the SG Appliance

The restart options control the restart attributes of the SG appliance if a restart is required because of a system fault.

Important: The default settings of the Restart option suits most systems. Changing them without assistance from Blue Coat Systems Technical Support is not recommended.

Hardware and Software Restart Options

The Restart settings determine if the SG appliance does a faster software-only restart, or a more comprehensive hardware and software restart. The latter can take several minutes longer, depending upon the amount of memory and number of disk drives in the appliance.

The default setting of Software only suits most situations. Restarting both the hardware and software is recommended in situations where a hardware fault is suspected.

For information about the Core Image settings, see “Core Image Restart Options” on page 57.

Note: If you change restart option settings and you want them to apply to the next SG appliance restart, click Apply.

To restart the SG appliance:

1.Select Maintenance > System and disks > Tasks.
