HP XC System Software Installation Guide Version 3.1

7. Do the following when the cluster_config utility displays the command-line options menu:
[L]ist Nodes, [M]odify Nodes, [A]nalyze, [H]elp, [P]roceed, [Q]uit:
a. If you specified 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.
b. If the head node was configured as a NIS slave server in HP XC Version 2.1, you must assign the
nis_server role to the head node now, because this role was introduced after Version 2.1. Use
the [M]odify option of the cluster_config utility to assign this role to the head node.
If you need more information about using the cluster_config command-line options menu to
make or modify role assignments, see Appendix G (page 143).
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 5-9.

10. Follow along on the system while the cluster_config utility configures the system.
NOTE: To avoid duplicating command output here, cluster_config output is shown on (page 70).
Continue to the next step in this procedure when the cluster_config utility 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 had previously customized this file,
you must merge those customizations into the new version of the
/hptc_cluster/slurm/etc/slurm.conf file. Otherwise, bypass this step.
12. Re-enter the monitoring line card entries in the /etc/dhcpd.conf file if the system is using a Myrinet
interconnect. See “Configure Myrinet Switch Monitoring Line Cards” (page 125) for more information
about adding entries to this file.
Bypass this step if the system is using an InfiniBand, QsNet
II
, or Gigabit Ethernet interconnect.
Proceed to “Task 9: Image and Boot the System and Start Compute Resources” (page 107).
