Manage node group members

 

Use this topic to manage the nodes in your node groups by viewing, adding or deleting the nodes in a node group. Read about Nodes groups if you are unfamiliar with them.

 

Overview

Make the nodes that you organize into a node group enough alike in terms of installed software, available resources, and configuration to enable servers on those nodes to host the same applications as part of a server cluster. Node group membership must adhere to the following rules:

• A node in a node group must be a managed node.

• A managed node must be a member of at least one node group. Initially, all WAS nodes are members of the default node group named DefaultNodeGroup.

• Nodes on distributed platforms and nodes on i5/OS platforms can be members of the same node group.

• Nodes on distributed platforms and i5/OS platforms cannot be members of a node group that contains a node on a z/OS platform.

 

Procedure

• View node groups members.

  1. Click System Administration > Node groups > node group name > Nodes > Node group members in the console navigation tree.

  2. To view additional information about a particular node group member for this node group, click on the node group member name under Name.

• Add a node to a node group.

  1. Click System Administration > Node groups > node group name > Nodes > Node group members in the console navigation tree.

  2. Click Add.

  3. Select the node from a list. The node group member name is the node name.

  The node group member is added to the node group specified on the breadcrumb trail. The name of the node group member appears in the name column of the Node group member page. You can add additional nodes of similar characteristics to the node group by repeating the steps for adding a node to a node group.

  If the node you add does not satisfy the node group membership rules for the target node group, the add node operation fails with an error message.

• Remove a node from a node group.

  1. Click System Administration > Node groups > node group name > Nodes > Node group members in the console navigation tree.

  2. Select the box next to each node group member to remove from the node group.

  3. Click Remove.

  Each node group member that you selected is removed from the node group specified on the breadcrumb trail.
