View Log
The SonicWALL also maintains an event log that displays these High Availability events in addition
to other status messages and possible security threats. This log may be viewed with a browser using
the SonicWALL Web Management Interface or it may be automatically sent to the administrator’s E-
mail address.
To view the SonicWALL log, click Log on the left side of the browser window and then click on View
Log at the top of the window.
Forcing Transitions
In some cases, it may be necessary to force a transition from one active SonicWALL to another – for
example, to force the primary SonicWALL to become active again after a failure when Preempt Mode
has not been enabled, or to force the backup SonicWALL to become active in order to do preventive
maintenance on the primary SonicWALL.
To force such a transition, it is necessary to interrupt the heartbeat from the currently active
SonicWALL. This may be accomplished by disconnecting the active SonicWALL’s LAN port, by
shutting off power on the currently active unit, or by restarting it from the Web Management
Interface. In all of these cases, heartbeats from the active SonicWALL are interrupted, which forces
the currently Idle unit to become Active.
