22.7.1 Gathering Information
You need to gather information on the nodes, the NIC, and the network to incorporate an external
NIC. This section discusses how to acquire that information and provides a worksheet you can
use to note the settings for your system.
Topics include:
• “Gathering Node-Specific Information” (page 282)
• “Determining NIC-Specific Information” (page 283)
• “Gathering Networking Information” (page 285)
• “Consolidating Information in the NIC Data Worksheet” (page 285)
22.7.1.1 Gathering Node-Specific Information
You need to know the following node-specific information before you can incorporate an external
NIC:
• The node name. That is, how the node is known to the HP XC system.
If the nodes have been discovered, entering the nodename command on a node returns its
node name.
• The model type of the node
Model numbers are displayed on the front of the node.
If the nodes of the HP XC system have been discovered, you can use the shownode config
command to determine the model numbers for the nodes in an HP XC system, as follows:
# shownode config | less
...
nodes:
...
n1:
...
server_type: server rx2600
...
IMPORTANT: The instructions to incorporate an NIC in an HP Integrity rx8620 server differ
slightly from other model types.
• The interconnect switch used
The configuration file you will update takes into consideration if Gigabit Ethernet or another
interconnect switch, such as Quadrics QSnet
II
, is used.
• The firewall configuration
By default, the firewall is configured automatically to open all external physical Ethernet
ports the same way: that is, virtual ports 22 (ssh) and 443 (https) are open by default. The
firewall prototype files are capable of configuring up to five external physical Ethernet ports
per node automatically as shipped; you can easily extend these files for additional external
physical Ethernet ports.
It is possible, however, that you need to custom configure the firewall for the extra external
network connections. In this version of the HP XC system software, services may not have
been modified to use the external ports automatically and you may need to configure the
firewalls appropriately for them.
