HP XC System Software Installation Guide Version 3.2.1

6. Change directory to the configuration directory:
# cd /opt/hptc/config/sbin
7. Specify one of the following cluster_config options:
• To migrate the existing system configuration:
# ./cluster_config --migrate
• To apply new default role assignments to the existing system configuration:
# ./cluster_config --init
8. If you followed the instructions in “Task 9: Plan a Service Availability Strategy” (page 26)
to install an availability tool and position related scripts to set up improved availability of
services, you are prompted to configure availability sets now. “Task 8: Configure Availability
Sets” (page 88) describes how to configure availability sets. Return here when you are done.
9. View the role assignments 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: l
• 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 207).
10. 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
11. The cluster_config utility prompts you to supply system configuration information.
When prompted, provide the answers listed in Table 5-7.
