Create a Cluster Wizard: Configure Nodes

Use this page to configure optional properties for the nodes that you selected to include in the new cluster.

Fields

Node name
The default value for the node name is the domain portion of the host name of the node. You can specify a different name for the node, if you prefer. The name must be unique within the cluster and must consist of 1 - 32 characters. You can use the characters of A - Z and a - z, the numbers of 0 - 9, and the underscore (_) character.
Persistent IP label/IP address
start of changeSpecify an optional Internet Protocol (IP) label or IP address that you want to keep bound (persistent) to this node.

Select a persistent IP label/address for this node from a list of discovered and available labels and addresses that exist in the /etc/hosts file. Alternatively, you can manually specify an IP address. The value that you specify must be unique within the cluster and capable of being supported by a network on the associated node.

end of change
Controlling node
start of changeSelect the node that must be the controlling node for the cluster. The controlling node is the primary point of contact between IBM® Systems Director and the PowerHA® SystemMirror cluster. All actions are performed exclusively on this node and all information is retrieved exclusively from this node. If, for any reason, PowerHA SystemMirror is unable to contact the controlling node, PowerHA SystemMirror reassigns the controlling node to a node that it can contact successfully.

The first node is the default selection for the controlling node for the cluster.
