Description

Only the HA primary unit will do the message forwarding/routing even though both nodes will contain the message routing configuration. The behavior of most other LogLogic LMI features is the same when in HA:

For scheduled reports on an HA pair of LX appliances, only the primary unit will actually execute the report
With an HA pair of ST appliances only the primary unit will actually write to the NAS/SAN

There is an exception to this. An index search can be executed on a standby node to take advantage of what would otherwise be idle resources on the standby appliance.
