- RECONNECT - Restore connections with machines that were previously detached.
- PREPJOIN - Prepare the addition of a new machine over CCS.

At this point you can add machines to the new cluster. Those machines can communicate via SSH or
CCS.
From the host you want to add to the cluster, issue the clusterconfig command to join the existing
cluster. You can choose to join the cluster over SSH or over CCS (cluster communication service).
In order to join a host to an existing cluster, you must:
be able to validate the SSH host key of a machine in the cluster
know the IP address of a machine in the cluster and be able to connect to this machine in the cluster
(for example, via SSH or CCS)
know the administrator password for the admin user on a machine belonging to the cluster
Note All machines you intend to add to the cluster must have the centralized management feature key installed
on them before they can be added to the cluster. It is also possible to join an existing cluster within the
systemsetup command if the feature key for centralized management has been installed on the system
prior to running the CLI system setup wizard and if a cluster exists. After changing the administrator
password, setting the hostname of the appliance, and configuring network interfaces and IP addresses,
the systemsetup will prompt you to create or join a cluster.
Joining an Existing Cluster over SSH
The following table demonstrates adding the machine losangeles.example.com to the cluster using the
SSH option.
losangeles.example.com> clusterconfig
