Prepare Primary Node
Use the Cluster Configuration form to enter the basic network and control parameters for the cluster.
If you have not already set a unique hostname for this server, you can do so here. Each node in the cluster
must have a unique hostname. You can selec a single virtual IP address by entering one IP address in the
Virtual IP Address field, or specify more than one virtual IP by entering a comma-separated list of multiple
IP addresses.
You must enter a shared secret for this cluster. The shared secret is used to authenticate the messages sent
between the nodes in the cluster.
For the downtime threshold parameter, See “Primary Node Failure” in this chapter.
High Availability Services requires an IPv4 multicast address and port number. By default these values are
226.94.1.1 on UDP port 4000. If this address and port combination overlaps an existing solution on your
network, you can adjust them when initializing the cluster configuration. If this multicast address is already
in use, the cluster initialization will not work and you will need to choose a different address. Click the
Advanced check box and enter an appropriate multicast address and port. These values will be
automatically synchronized on the secondary node.
Click the Save and Continue button to prepare the primary node.
Each node in the cluster must be able to resolve the other node by using a DNS lookup. This is verified during the
cluster initialization. In practice, this means that you must configure your local DNS or DHCP server with appropriate
entries for each node.
Any switch equipment the Amigopod appliances are connected to should also be configured to allow IPv4 multicast
traffic.
