Cluster registration

Before you register or unregister a node in a cluster, consider these registration rules.

• You must activate your products on the primary master before you activate the product on any other nodes.

  If you are using the internal runtime database in a cluster, you must also activate the product on the secondary master before the other nodes.

  For more information about the activation process, see Activating the product and buying support.

• A node cannot be registered with a cluster if it is already a member of another cluster. In this situation, the node must first be unregistered from its current cluster.
• Node registration must occur directly through the local management interface of the appliance that you want to join the cluster. The appliance that you are registering must be able to communicate with the primary master.
• Node unregistration must occur on the primary master.
• A node cannot be unregistered if it is configured as a master. You must first demote the node from master and promote another node as the master.
