In the Network Settings page, open the DNS tab.
Make sure the host name is a unique host name for the HA-Secondary CAS, such as "rjcas_2." You
must have the same domain name specified in this tab as you did for the HA-Primary CAS (see
Configure the Host Information for the HA-Primary CAS, page
When configuring HA, it is mandatory to specify a Host Name for each machine in the HA-pair.
The Host Name is case-sensitive and cannot be an IP address. Host Names are needed later for
the Local Host Name and Peer Host Name fields of the HA Primary and HA Secondary
configuration. The Local Host Name and Peer Host Name do not need to be resolvable via
DNS; however, they are case-sensitive and need to match the Host Names you have specified for
the machines.
Click the Failover > General tab and select HA-Secondary Mode from the Clean Access Server
Mode dropdown menu.
