HP XC System Software Installation Guide Version 4.0

netMask The netmask that is used for all connections on the administration
network.
dyStart The start of the dynamic IP address range used during the discovery
process. This parameter is present only in the base_addrV2.ini
file.
dyEnd The end of the dynamic IP address range used during the discovery
process. This parameter is present only in the base_addrV2.ini
file.
3. Follow these guidelines if you make changes to the base_addr.ini or base_addrV2.ini
files:
• Modify only the first two octets of a base address.
• Use a private domain as defined by the RFC.
• Verify that the netmask is correct for the changes you make. Otherwise, the discover
process fails.
4. Save the changes to the file and exit the text editor. 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.
5. If you made changes to the IP addresses in the base_addrV2.ini file, repeat steps 1
through 4 to edit the base_addr.ini file and make the same changes.
3.4 Running 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 by invoking the cluster_prep command. An
additional command line option is required if the hardware configuration contains HP server
blades and enclosures or if you are adding planned (but not present) compute nodes to your
configuration.
CommandSituation
# ./cluster_prep
The hardware configuration does not contain HP server
blades and enclosures and you are not configuring
future planned compute nodes into the hardware
configuration
# ./cluster_prep --enclosurebased
The hardware configuration contains HP server blades
and enclosures, you are configuring future planned
compute nodes into the hardware configuration, or
both
Command output is similar to the following. Table 3-1 (page 54) describes each prompt and
provides information to help you with your answers.
