HP Insight Cluster Management Utility v7.1 User Guide

To modify the attributes of a node, select the node in the Node Management list, and then select
Modify Node. The same interface as Add Node appears.
NOTE: The node name cannot be changed.
3.4.1.4 Importing nodes
Cluster Administration→Node Management→Import Node
To import nodes from a flat text file, select an existing text file and then click Open to import all
the nodes from this file into the HP Insight CMU database. The following is a sample import/export
file:
cn001 16.16.184.40 255.255.248.0 1C-C1-DE-6E-24-AE default 16.16.188.40 lo100i
cn002 16.16.184.41 255.255.248.0 1C-C1-DE-EA-49-74 default 16.16.188.41 lo100i
cn003 16.16.184.42 255.255.248.0 1C-C1-DE-EA-28-F6 default 16.16.188.42 lo100i
cn004 16.16.184.43 255.255.248.0 1C-C1-DE-E8-ED-2C default 16.16.188.43 lo100i
cn005 16.16.184.118 255.255.248.0 78-E7-D1-FA-8A-C0 default 16.16.188.118 ILO
NOTE: This file can be manually created and edited, but incorrect formatting can break the
operation.
All the imported nodes belong to the default logical group.
3.4.1.5 Deleting nodes
Use this interface to delete a node from the HP Insight CMU database. Select any number of nodes
in the nodes list, and then click Delete Node.
IMPORTANT: After deleting a node, you cannot recover its attributes.
3.4.1.6 Exporting nodes
To export node attributes to a flat text file, select one or several nodes in the Node Management
window, click Export Node and then save the file.
3.4.1.7 Contextual menu
Select one or several nodes in the Node Management window. To display a contextual menu
window, right-click the selected node or nodes.
The contextual menu options are:
• Delete Nodes invokes the delete node procedure for the selected nodes. This feature is
equivalent to selecting the Delete Node option from the Node Management menu.
• Change Active Group changes the active group of all selected nodes. The node appears in
the new group in the Monitoring by Logical Group window.
• Modify Node invokes the modify node procedure for the selected node. This feature is equivalent
to selecting the Modify Node option from the Node Management menu. This menu item is
only active when one node is selected from the list.
• Add Node invokes the add node procedure. This is equivalent to selecting the Add Node
option from the Node Management menu.
3.4.2 Network entity management
A network entity in HP Insight CMU corresponds to a single network switch that connects to a
group of nodes. Large clusters have more than one network switch. The cloning process attempts
to maximize the available network bandwidth within each of the Ethernet switches used in the
cluster. To accomplish this, a unique network entity must be created for each group of nodes
connected to a single Ethernet switch used within the cluster.
IMPORTANT: Cloning will not work for nodes that do not belong to a network entity.
