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.
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.
To restart the SG appliance:
1. Select
Maintenance > System and disks > Tasks.
Important: The default settings of the Restart option suits most systems. Changing
them without assistance from Blue Coat Systems Technical Support is not
recommended.
Note: If you change restart option settings and you want them to apply to the next SG
appliance restart, click
Apply.
