Create Cluster Wizard - Choose Nodes

Use this page to choose nodes to include in the new cluster.

A cluster node is a system unit that participates in an PowerHA™ SystemMirror cluster as a server. A node can be an IBM® System p® system unit, or a logical partition (LPAR) within a partitioned System p server system unit, that is running a supported level of AIX® and meets the minimum requirements for internal memory, internal disk, and I/O slots.

All the nodes that you include in the cluster must meet the following prerequisites:

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.

Select one or more host names in the table that you want to include as nodes in the new 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.

Actions

Common Storage
Click Common Storage in the Choose Nodes table task bar or select this action from the Actions menu to view a list of storage disks that are common to all selected nodes. The selected nodes must have at least one storage disk in common among them. A common storage disk must be available for use as the cluster central repository, which contains configuration and other data for the cluster. There must be at least one common storage disk common among all the selected nodes or you cannot complete the wizard to create the cluster.
