4.2 Ethernet Port Connections on the Head Node

Table 4-2lists the Ethernet port connections on the head node based on the type of interconnect in use. Use this information to determine the appropriate connections for the external network connection on the head node.

IMPORTANT: The Ethernet port connections listed in Table 4-2do not apply to hardware configurations with HP server c-Class blades and enclosures.

4.3 General Hardware Preparations for All Cluster Platforms

Make the following hardware preparations on all cluster platform types if you have not already done so:

1.The connection of nodes to ProCurve switch ports is important for the automatic discovery process. Ensure that all nodes are connected as described in “Making Node and Switch Connections” (page 45).

2.When possible, ensure that switches are configured to obtain IP addresses using DHCP. For more information on how to do this, see the documents that came with the ProCurve hardware. ProCurve documents are also available at the following Web page:

IMPORTANT: Some HP Integrity hardware models must be configured with static addresses, not DHCP. For HP XC systems with one or more of these hardware models, you must configure all the nodes with static IP addresses rather than with DHCP. The automatic discovery process requires that all nodes be configured with DHCP or with static IP addresses, but not a combination of both methods.

3.Ensure that any nodes connected to a Lustre® file system server are on their own Gigabit Ethernet switch.

4.Ensure that all hardware components are running the correct firmware version and that all nodes in the system are at the same firmware version. See “Firmware Requirements and Dependencies” (page 59) for more information.

5.Nagios is a component of the HP XC system that monitors sensor data and system event logs. Ensure that the console port of the head node is connected to the external network so
