HP XC System Software Installation Guide Version 3.2

and the file you modify depends on whether or not HP server blades and enclosures are included
in the hardware configuration.
base_addr.ini file
Modify this file if the hardware configuration does not contain
HP server blades and enclosures.
base_addrV2.ini file.
Modify this file if the hardware configuration contains HP
server blades and enclosures. You must make the same
modifications to the base_addr.ini file.
Follow this procedure to change the default IP address base for the XC private networks:
1. Begin this procedure as the root user on the head node.
2. Use the text editor of your choice to edit either the /opt/hptc/config/base_addr.ini
or base_addrV2.ini files.
The default contents of this file is similar to this:
Base = 172
nodeBase = 172.20
cpBase = 172.21
swBase = 172.20.65
icBase = 172.22
otherBase = 172.23.0
netMask = 255.224.0.0
dyStart=172.31.48.1

dyEnd=172.31.63.254

These parameters are present only in the base_addrV2.ini file.
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.
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:
Change only the first two octets of a base address.
Use the same first two octets for all base IP addresses.
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.
