file, 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.
If you modify the IP addresses in the base_addrV2.ini file,
you must modify the base_addr.ini file with the same
changes.
The only exception is the dyStart and dyEnd parameters,
which are not required nor used in 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
file or the /opt/hptc/config/base_addrV2.ini file.
Example 3-1 shows the default content of the base_addr.ini file.
Example 3-1 Default Content of the base_addr.ini File
Base = 172
nodeBase = 172.20
cpBase = 172.21
swBase = 172.20.65
icBase = 172.22
otherBase = 172.23.0
netMask = 255.224.0.0
Example 3-2 shows the default content of the base_addrV2.ini file.

The dyStart and dyEnd parameters are present only in the base_addrV2.ini
file and are not required nor used in the base_addr.ini file. If you change these
IP addresses, do not add these parameters to the base_addr.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.
