Under the unit view, GMS displays whether an appliance is the primary or secondary unit on the System>Status page under the Management heading. For more information, refer to Viewing System Status .Another method to determine which SonicWALL is active is to check the High Availability Settings Status indicator on the High Availability > Settings page. If the primary SonicWALL is active, the first line in the page indicates that the primary SonicWALL is currently Active. It is also possible to check the status of the backup SonicWALL by logging into the LAN IP Address of the backup SonicWALL. If the primary SonicWALL is operating normally, the status indicates that the backup SonicWALL is currently Idle. If the backup has taken over for the primary, the status indicates that the backup is currently Active.Using the GEM framework, you can also configure GMS to send email alerts when there is a change in the status of the High Availability pair. You can configure an alert using the Unit HF Status alert type. For information on how to configure alerts, see Configuring Granular Event Management .You can also view details on High Availability events in the GMS log that is available on the Console tab under the Log tree. Refer to Configuring Log Settings for more information.
