HP XC System Software Installation Guide Version 3.2

• HP recommends that you use the [L]ist Nodes option to see the roles assigned to
each node and make adjustments if required.
• If you ran the cluster_config command with the --init option, use the [M]odify
Nodes option to reassign any role assignments you customized in the previous release.
For example, if the system configuration had login roles on one or more nodes, you
must assign a login role on any node on which you want users to be able to log in. In
the default configuration, a login role is not assigned to any node.
• If you need more information about using the cluster_config command-line options
menu to modify role assignments, see Appendix G (page 215).
8. When you have finished making role assignments, enter the letter p to proceed with the
system configuration process:
[L]ist Nodes, [M]odify Nodes, [A]nalyze, [H]elp, [P]roceed, [Q]uit: p
Do you want to apply your changes to the cluster configuration? [y/n] y
[S]ervices Config, [P]roceed, [Q]uit: p
Do you want to apply your changes to the service configuration? [y/n] y
9. The cluster_config utility prompts you to supply system configuration information.
When prompted, provide the answers listed in Table 5-7.

10. Follow along on the screen while the cluster_config utility configures the system.
NOTE: To avoid duplicating command output here, cluster_config output is shown
in “Task 10: Respond to Configuration Questions” (page 90).
Continue to the next step in this procedure when the cluster_config processing is
complete.
11. Look at the backup copy of the slurm.conf file, which is located in the
/hptc_cluster/slurm/etc/slurm.conf.bak file. If you previously customized this
file, you must merge those customizations into the new version of the
/hptc_cluster/slurm/etc/slurm.conf file. Otherwise, omit this step.
