Starting the Restore Utility Using Lights-Out Management
If you need to restore an appliance to factory defaults and do not have physical access to the appliance, you can
use LOM to perform the restore process. Note that if you want to use LOM to configure the initial setup, you
must
preserve the network settings during the initial setup. Note also that you can use Lights-Out Management on the
default (
eth0
) management interface only.
Note:
Before you can restore an appliance using LOM, you must enable the feature; see
