HP XC System Software Installation Guide Version 3.0

Description and User ActionItem
If you modified the default role assignments and assigned a nis_server role to configure one
or more nodes as a NIS slave server, you are prompted to enter the name of your NIS master
server or its IP address as well as your NIS domain name.
NIS configuration
You are prompted for the following information about your SLURM configuration:
• Whether or not to configure SLURM (it is only required if LSF HPC is also installed)
• A SLURM user name. A default value is provided, but you can specify your own SLURM user
name.
• The node on which to configure the primary SLURM controller
• The node on which to configure the backup SLURM controller
• Whether or not to configure user-restricted access on the compute nodes
SLURM configuration
You are prompted for the following LSF configuration information (default responses are provided
for each item):
• Whether or not you want to configure LSF
• What type of LSF to install: LSF-HPC with SLURM or standard LSF
• A user name for the primary LSF administrator (if you have not configured NIS)
• A password for the LSF administrator
• An LSF host name
LSF configuration
Task 2: Change the Default IP Address Base (Optional)
You may need to change the default IP address base of the XC private networks if the default values conflict
with another IP address base at your site.
Follow this optional 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 the /opt/hptc/config/base_addr.ini file.
The default contents of this file looks like 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
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.
Any changes you make to this file must follow these guidelines:
• You can change only the first octet of a base address; 172 is the default.
• All base IP addresses must use the same first octet.
• You must use a private domain as defined by the RFC.
3. 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, use :w! to save changes to a read-only file.
