HP XC System Software Installation Guide Version 4.0

Table 9-7 Upgrade Options for the cluster_config Utility
--init Option--migrate Option
Initializes (resets) current node role assignments and
configures the system with the default node role
assignments in this release.
This option does not preserve role-to-node assignments
from the previous release.
The default roles and assignments have been optimized
for performance and, you might decide that this
configuration is better suited for your environment.
See Appendix F (page 215) for a description of roles
and the services provided by them, as well as the
default node role assignments.
Brings existing, recognized roles in the configuration
and management database into alignment with the
new roles introduced in this release.
This option retains information about role assignments
and preserves role-to-node assignments.
Using this option does not guarantee the correct
migration process for unrecognized (user-created) roles
and services in the configuration and management
database.
Before you decide to use this option, view the /opt/
hptc/etc/sysconfig/upgrade/
role_migration.ini file to see how the previous
role assignments compare to the roles provided in the
new release.
5. Verify that the newly created HP XC golden image is a reasonable size (typically 2 to 3 GB)
otherwise the imaging process might fail.
# du –sk /var/lib/systemimager/images/base_image
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 Section 1.9 (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. Section 6.3 (page 101) 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 223).
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
