Configuring High Availability
Note HP recommends that you change the HA VLAN to a dedicated VLAN that does
not carry general data traffic, even if you are not implementing HA. If you do
not change the HA VLAN, general broadcast traffic will be received by the
module on VLAN 1 and then dropped by the firewall. If firewall logging is set
at Minor or below, you will see the following log message: “FW: packet
appeared with invalid interface name. Packet dropped.”
To configure HA settings, complete the following steps on each module. Remem-
ber that the order in which you configure and reboot the members of an HA
cluster is extremely important. (See “Configuration and Boot Order for HA
Members” on page 8-4.) You should configure the intended master first and
reboot it. You may even consider waiting for the master to complete the reboot
process before configuring the other module in the cluster. This will ensure that
the intended master is booted into the cluster before the other module
1. Back up the startup-config. If you need to restore the startup-config,
remember that it does not include the HA settings.
a. Click System > Maintenance. Then click the Back Up/Restore tab.
b. Click Back Up and save the configuration to your workstation.
Note It is extremely important that you back up the configuration on the cluster
master. In the event that your configuration is lost, you can use this to
reconfigure the cluster.
2. Select System > Settings and click the High Availability tab.
