3 Configuring and Imaging the System
This chapter contains an overview of the initial system configuration and imaging process and
describes system configuration tasks, which must be performed in the following order:
• “Task 1: Prepare for the System Configuration” (page 53)
• “Task 2: Change the Default IP Address Base (Optional)” (page 60)
• “Task 3: Run the cluster_prep Command to Prepare the System” (page 61)
• “Task 4: Install Patches or RPM Updates” (page 64)
• “Task 5: Run the discover Command to Discover Hardware Components” (page 65)
• “Task 6: Set Up the System Environment” (page 76)
• “Task 7: Run the cluster_config Utility to Configure the System” (page 87)
• “Task 8: Configure Availability Sets” (page 88)
• “Task 9: Modify and Assign Node Roles” (page 90)
• “Task 10: Respond to Configuration Questions” (page 92)
• “Task 11: Edit the /etc/dhcpd.conf File” (page 101)
• “Task 12: Run the startsys Utility to Start the System and Propagate the Golden Image”
(page 102)
• “Task 13: Perform Postconfiguration Tasks for the InfiniBand Interconnect” (page 105)
• “Task 14: Create a Lock LUN Device File” (page 106)
• “Task 15: Start Availability Tools” (page 106)

3.1 System Configuration and Imaging Overview
This section provides an overview of the initial system configuration and imaging process.
3.1.1 System Configuration Process
The system configuration process is the method by which the topology of the system is
automatically discovered, applied, and stored in the configuration and management database
after the installation of the head node has been completed.
The system topology is defined based on the manner in which the head and client nodes are
connected to the administration network when the nodes are cabled into the appropriate switches.
The system configuration procedure described in this chapter consists of running the following
HP XC commands and utilities:
DescriptionCommand or Utility Name
Prepares the system for discovery and configuration and configures the
external Ethernet device on the head node, thus enabling network
connectivity
cluster_prep
Discovers and enables all hardware components and populates the
/etc/hosts and /etc/dhcp.conf files
discover
