In this scenario, the primary node has failed and the standby
node has taken over as the new primary node. Before a new backup can
be powered on, the new primary node fails. You need to restart both
nodes. System administrators can use the High Availability page
in the Amlen WebUI.
You can configure appliances for high availability by
using the Amlen WebUI,
or by using the command line. For more information about using the
command line to configure appliances for high availability, see Bring back primary and standby nodes after both nodes fail by using the command line. In this scenario, the content of the
store and configuration of Appliance B is preserved.
- Check the high availability configuration on Appliance
B is correct by selecting High Availability from
the Appliance menu. If you change any settings,
click Save.
- Click Restart Later when prompted.
- Stop and then restart the Eclipse Amlen server for both
of the appliances:
Tip: As a best practice,
stop and restart the standby server first. Then stop and restart the
primary to limit the amount of time that the primary spends waiting
for the standby to become available.
- Click System Control in the Appliance menu.
- Stop the server by clicking Stop the server.
- Start the server by clicking Start the server.
When the HA pair is up and running, you can view the status
of each appliance from the Status menu on the Amlen WebUI. You can view
further information on the status of the appliance by using the System
Control page. You can view further information about the
high availability role of the appliance by using the High
Availability page.
