Fields

Choose nodes
The Choose nodes table lists the host names of all available nodes that meet the prerequisites for inclusion in a cluster. The table does not include any host names of nodes that are already included in an existing cluster.

When you make the first selection, the entries in the table are updated so that you cannot select host names that are not compatible with the one you first selected. A minimum of two nodes are required for the new cluster. The maximum number of nodes allowed for a cluster is 32.
