After you have set up your management hosts using the "egoconfig mghost" command, you can modify the master candidate list in the Platform Management Console.
Navigate to in the Platform Management Console.
Add or remove hosts from the master candidate list, as required.
Position the hosts in the list. The first host in the list will become the master host. The hosts that follow it will be candidate master hosts, should the first host be unavailable.
Alternatively, you can modify the master candidate list from the command line by running "egoconfig masterlist hostA,hostB". Again, the first host in the list will become the master host. The hosts that follow it will be candidate master hosts, should the first host be unavailable.
Run "egosh ego restart" on all master host candidates to allow the changes to take effect.
