Add Resource Group Wizard - Choose nodes

Use this page to specify the nodes on which you want to create the new resource group.

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.

Fields

Available nodes
Available nodes lists all discovered cluster nodes within the chosen cluster. Select each node that you want to participate in the new resource group, then click > to move the node to Selected nodes. Select nodes in order of priority, from top to bottom, for handling failover in case of a node failure.
Note: You must select at least one node; however, at least two nodes are necessary to make a resource group highly available.
Selected nodes
Selected nodes lists all cluster nodes that you have selected for the resource group from the Available nodes list. You can remove a node from the resource group by selecting the node, then clicking the < to move the node to back to Available nodes. To change the order of priority of a node, select it in the list and click the appropriate arrow next to the list to move the node up or down in the list.
