HA License Configuration Overview
You can configure HA license synchronization by associating
two Dell SonicWALL security appliances as HA Primary and HF
secondary on MySonicWALL. Note that the secondary
appliance of your HA pair is referred to as the HF Secondary
unit on MySonicWALL. Also note that the secondary appliance
must be an identical model to the primary applicancy (such as
two NSA E5500 appliances).
You must purchase a single set of security services licenses for
the HA Primary appliance. To use Stateful HA, you must first
activate the Stateful High Availability Upgrade license for the
primary unit in SonicOS. This is automatic if the appliance is
connected to the Internet. See
Appliance on MySonicWALL, on page 20.
Registering and Licensing the
License synchronization is used during HA so that the
secondary appliance can maintain the same level of network
protection provided before the failover. To enable HA, you can
use the SonicOS UI to configure your two appliances as a HA
pair in Active/Idle mode.
MySonicWALL provides several methods of associating the two
appliances. You can start by registering a new appliance, and
then choosing an already-registered unit to associate it with.
You can associate two units that are both already registered. Or,
you can select a registered unit and then add a new appliance
with which to associate it.
Note: After registering new Dell SonicWALL appliances on
MySonicWALL, you must also register each appliance
from the SonicOS management interface by logging
into the unique IP address assigned on the High
Availability > Monitoring page and then clicking the
registration link on the System > Status page. This
allows each unit to synchronize with the license server
and share licenses with the associated appliance.
