HP XC System Software Installation Guide Version 3.2

Table 3-3 Information Required by the cluster_config Utility (continued)
Description and User ActionItem
If you installed SVA or optional remote graphics software,
1
you are prompted
to supply the following information:
• Whether the visualization nodes (the workstations) have a KVM attached
• The host names for display nodes, that is, the nodes that have monitors
connected to them
• Remote graphics software configuration information:
— The host names of the remote graphics nodes. You must configure external
connections on these nodes.
— Whether you want to use RGS sender on the head node. Doing so enables
the head node to display remote nodes (for HP RGS only).
— Whether you want to use RGS Receiver Version 3.0 to connect the system
(for HP RGS only).
Answering yes means that multiple ports are opened on the firewall.
Answering no opens a single port on the firewall.
The current version of HP RGS is Version 4.n. Version 4.n receivers require
a single port opened in the firewall. If you choose to continue using
previously installed HP RGS Version 3.0 receivers, multiple ports are
opened in the firewall. You can use only Version 4.n receivers or a mix of
Version 4.n and Version 3.0 receivers.
For more information about HP RGS and its use of firewalls, see the SVA
System Administration Guide .
SVA and remote graphics
software 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 you want to configure SLURM. You are not required to configure
SLURM, however, SLURM is required by LSF-HPC with SLURM and SVA.
• 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 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 you want to configure LSF. You are not required to use LSF as the
job management software.
• 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)

1 SVA supports the use of HP Remote Graphics Software (HP RGS) and the third-party Virtual GL remote
graphics software.
3.3 Task 2: Change the Default IP Address Base (Optional)
You might have 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 address base is stored in a *.ini file,
