HP XC System Software Installation Guide Version 3.1

Table 3-3 Information Required by the cluster_config Utility (continued)
Description and User ActionItem
If you assigned the external role to the nodes in an availability set, you are prompted
to specify how you want to handle improved availability for the nat service. You can
choose between no improved availability or enabling improved availability through an
availability tool.
You are also prompted to enter an additional external IP address to use as an external
alias.
NAT configuration
You are prompted to configure the snmptrapd service if the hardware configuration
includes HP server blade enclosures or if you have defined an mcs.ini file to configure
MCS devices.
snmptrapd service configuration
You are prompted to configure a self-signed certificate for the Apache server so that all
HP XC systems do not have the same credentials. If you do not configure a self-signed
certificate, the certificate that is shipped with the Linux base operating system is used
instead, which prevents some web browsers from being able to connect to more than one
HP XC system during the same session.
Apache self-signed certificate
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 the NIS
master server or its IP address as well as the NIS domain name.
NIS configuration
You are prompted for the following information about the SLURM configuration:
• Whether or not to configure SLURM
• 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
• A password for the LSF administrator if it is a new local account
• An LSF cluster name (the default is hptclsf)
LSF configuration
3.3 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. The IP address base is defined in the base_addr.ini
file.
Important Note About HP Server Blades and Enclosures:
If the hardware configuration contains HP server blades and enclosures, the IP address base is different,
and it is defined in the base_addrV2.ini file.
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
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 is similar to this:
Base = 172
nodeBase = 172.20
cpBase = 172.21
swBase = 172.20.65
icBase = 172.22
