You should backup your configuration on both CC-SG units before creating a cluster.
To create a cluster:
Choose Administration > Cluster Configuration.
The CC-SG you are currently accessing displays in the Primary Secure Gateway IP Address/Hostname field, indicating that it will become a Primary Node.
Specify a Secondary, or Backup, Node in the Backup Secure Gateway IP Address/Hotsname field. Make sure the specified CC-SG has the same firmware version and hardware type as the Primary Node. Use one of these methods to specify it:
Click Discover Secure Gateways to scan and display all CC-SG units on the same subnet as the one you are currently accessing. Then click a CC-SG unit in the Standalone state from the table of discovered CC-SG units to select it.
You can specify a CC-SG, perhaps from a different subnet, by typing an IP address or hostname in the Backup Secure Gateway IP Address/Hostname field. Then click Check Backup to verify whether it has the same firmware version and hardware type as the Primary Node.
Type a name for this cluster in the Cluster name field.
Type a valid user name and password for the Backup node in the Username for Backup Secure Gateway and Password for Backup Secure Gateway fields.
Select the Redirect by Hostname checkbox to specify that secondary to primary redirection access should be via DNS. Optional. See Access a CC-SG Cluster. If you're using hostnames instead of IP addresses, the DNS server should contain reverse lookup records for the IP addresses of the CC-SGs to ensure the hostnames can be resolved.
Click Create Cluster. A message appears.
Click Yes.
Important: Once you begin the cluster creation process, do not perform any other functions in CC-SG until the process has completed.
Continue clicking OK for any onscreen messages. The Backup node will restart and the process takes several minutes.
When the cluster creation is complete, a message appears, indicating the Backup node is successfully joined.
