HP XC System Software Installation Guide Version 3.1

otherBase = 172.23.0
netMask = 255.224.0.0
The following describes the parameters in this file:
Base The common first octet that is used for all base IP addresses.
nodeBase The base IP address of all nodes.
cpBase The base IP address of the console branch.
swBase The base IP address of the Ethernet switches. The interconnect switch modules
are based off of this value, 172.20.66.*.
icBase The base IP address of the interconnect.
otherBase The base IP address to be used for other devices. This value is currently not
used by the discovery process.
netMask The netmask that is used for all connections on the administration network.
3. Follow these guidelines if you make changes to the base_addr.ini file:
• Change only the first octet of a base address; 172 is the default.
• Use the same first octet for all base IP addresses.
• Use a private domain as defined by the RFC.
4. Save your changes and exit the file. Because this is a read-only file, the method by which you save
the file depends upon the text editor you used.
For example, if you are using the vi text editor, enter :w! to save changes to a read-only file.
Proceed to “Task 3: Run the cluster_prep Command to Prepare the System” .
3.4 Task 3: Run the cluster_prep Command to Prepare the System
The first step in the configuration process is to prepare the system by running the cluster_prep command.
This process sets up the node naming prefix, the number of nodes in the system, the configuration and
management database administrator's password, the external Ethernet connection on the head node, starts
the MySQL service, and initializes the configuration and management database.
1. Begin this procedure as the root user on the head node.
2. Change to the following directory:
# cd /opt/hptc/config/sbin
3. Start the system preparation process:
# ./cluster_prep
Important Note About HP Server Blades and Enclosures:
You must include the --enclosurebased option if the system is configured with HP server blades.
For more information, see the HP XC Systems With HP Server Blades and Enclosures HowTo, which is
available at the following Web site:
http://www.docs.hp.com/en/highperfcomp.html
Command output is similar to the following. Table 3-1 (page 45) describes each prompt and provides
information to help you with your answers.
The cluster_prep utility prepares the head node for the
automated discovery process. This utility is run during the initial
cluster configuration or any time your cluster is reconfigured.
If you reconfigure your cluster, you must run the discover
command after running the cluster_prep utility.
