WARNING! If you accidentally configure both IWSVA devices as parent or active
devices in transparent bridge mode, a network loop can be created. To
avoid this possibility, please configure each IWSVA as a forward proxy
device before configuring the HA feature.
To configure an IWSVA HA cluster:
1. Install two IWSVA devices in forward proxy mode. One will become the parent
active device and the other will become the child passive device.
2. Because IWSVA devices can be installed on generic server hardware, you will need
to confirm the network card and network information prior to setting up the HA
cluster. Gather the network card information that will be used in the Web UI
configuration steps to finalize the HA cluster configuration. This is performed by
logging into the IWSVA's CLI console and executing the following CLI command:
show network interface status
3. Make sure both IWSVA devices are connected to the network using the active
network card identified in the previous step. Both IWSVA units must be able to
communicate with each other and the management host that will be used to
configure the HA cluster.
4. From your management host, use the browser to connect to the IWSVA device that
is to act as the parent or active member. If this is the first time you've accessed the
IWSVA's Web console after the initial installation, the Deployment Wizard will start
automatically. You can also access it from the Administration > Deployment
Wizard menu option.
5. Follow the on-screen instructions in the Deployment Wizard to configure the first
HA cluster member. This will be the parent or active unit.
6. Repeat steps 4 and 5 for the IWSVA device that will be the child member. The child
member will join the parent member to complete the HA cluster.
Please refer to Chapter 3, High Availability and Cluster Management in the IWSVA
Administrator’s Guide for details about creating HA clusters.
