Use the Edit task on the page to view and change

Fields
- Name
- This field specifies the unique name of the selected resource
group.
- 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 the Participating nodes list.
Select nodes in order of priority, from top to bottom, for handling
failover in case of a node failure.
- Participating nodes (in priority order)
- Participating nodes lists all cluster nodes
that are currently participating in the specified resource group.
The nodes in this list are either ones that were configured for the
resource group when it was created, or ones 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.
Note: There
must be at least one participating node; however, two or more nodes
are necessary to make a resource group highly available.
- Other Resource Group Settings
- Enable WPAR
- This field indicates whether Workload Partitions (WPAR) are enabled.
WPARs are virtualized operating system environments, created by software,
within a single instance of the AIX® operating
system. This field specifies that all PowerHA™ SystemMirror
application servers in the current resource group are to run in the
specified WPAR. In addition, all service label and file system resources
that are part of this resource group are assigned to the specified
WPAR.
