HP Insight Cluster Management Utility manual Planning for compute node installation

2.1.2 Planning for compute node installation

Two IP addresses are required for each compute node.

•Determine the IP address for the management card (iLO) on the management network.

•Determine the IP address for the NIC on the administration network.

HP recommends assigning contiguous ranges of static addresses for nodes located in the same rack. This method eases the discovery of the nodes and makes the cluster management more convenient.

The management cards must be configured with a static IP address. All the compute node management cards must have a single login and password.

NOTE: HP Insight CMU uses DHCP and PXE. Do not run other DHCP or PXE servers on the HP Insight CMU management network in the range of ProLiant MAC addresses belonging to the HP Insight CMU cluster.

NOTE: The settings described in this document are based on the assumption that the administration network on each compute node is connected to, and will PXE boot from, NIC1. While this configuration enables all supported hardware to be imaged by HP Insight CMU, some operating systems might not configure eth0 as NIC1. For example, RHEL5.4 on the ProLiant DL385 G6 Server defaults eth0 to NIC3. To simplify the installation process for your operating system, HP recommends wiring your administration network to the NIC that defaults to eth0 and set that NIC to PXE boot rather than NIC1.

2.1.3 Disk space requirements

A total of 300 MB of free disk space is necessary to install all the subsets or packages required for HP Insight CMU. Up to 4 Gb of additional space is needed to store each master disk image.

2.1.4 Firmware upgrade requirements

Depending on the type of compute nodes in the cluster, you might have to upgrade the firmware on each compute node.

IMPORTANT: All compute nodes must have the same firmware version.

2.1.5 Configuring the local smart array card

HP Insight CMU does not configure local disks. If you have a hardware RAID controller, configure a logical drive to be used later by the operating system. The same logical drive must be created on each compute node.

The Compaq Array must be configured on each node of the cluster. You can choose any RAID level. If you have only one physical drive, before performing the initial operating system installation, configure it in a logical RAID0 drive. Otherwise, the disk is not detected during the Linux installation procedure and during the cloning procedure.

2.1.6 Configuring the management cards

To configure the management cards such as iLO:

1.Power on the server.

2.Access the management card.

3.Assign the same username and password to all management cards.

4.Assign a fixed IP address to each management card.
