4.3.1 Node management
Figure 7 Node management window
In Figure 7 (page 45), the node list of the cluster will appear as the node database is populated
by adding, scanning, or importing nodes. Each node is represented by a line containing the
following attributes:
• Node name
• Node IP address
• Netmask of the node
• MAC address of the node
• Logical group that cloned the node
• IP address of the management card of the node, or none if unused
• The type of management card on the node which can be iLO, LO100i, ILOCM, or none
• The architecture of the compute node (x86_64 is the default)
The Node Management window enables you to perform the following tasks:
• Add nodes to the HP Insight CMU database
• Delete nodes from the HP Insight CMU database
• Modify node attributes in the HP Insight CMU database
• Scan nodes to automatically add them to the HP Insight CMU database
• Import nodes
• Export nodes
IMPORTANT: Compute node numerical part names must contain zeroes as placeholders for the
highest node number in the cluster. For example, if the highest node number is 100, nodes must
be called cn001...cn100. If the highest node number is 1000, nodes must be called
cn0001...cn1000. Otherwise, some HP Insight CMU commands will parse nodes out of numerical
order.
