Follow this procedure to
use the cluster_config utility to view the default system
configuration and reassign roles to nodes where necessary. This task is especially
important if you are configuring services for improved availability. When the following command-line menu
options are displayed, enter the letter h or the word help to
display a description of each menu option. Entries are not case sensitive. [L]ist Nodes, [M]odify Nodes, [A]nalyze, [H]elp, [P]roceed, [Q]uit: h
Valid commands are:
L - Lists discovered nodes with current location, assigned roles,
and external network connections
M - Modifies nodes with the Modify Node submenu
A - Analyze current configuration
H - Displays this help message
P - Proceeds to the next cluster configuration step
Q - Quits this utility leaving the cluster unmodified
[L]ist Nodes, [M]odify Nodes, [C]heck, [H]elp, [P]roceed, [Q]uit: |
Enter the letter l to
list the default configuration; then enter the letter b or
the letter a to view an abbreviated or full version
of the output: [L]ist Nodes, [M]odify Nodes, [A]nalyze, [H]elp, [P]roceed, [Q]uit: l
Output Type - a[B]breviated, [A]ll, [C]ancel: |
The a[B]breviated output
is similar to the following. Nodes with the same role assignments are condensed
into one line item. Node: n16 location: Level 1 Switch 172.20.65.1, Port 42
CURRENT HEAD NODE
Roles assigned: compute console_network disk_io external
management_hub management_server resource_management
External Ethernet name: penguin.southpole.com
ipaddr: 192.0.2.0 netmask: 255.255.252.0 gateway: 192.0.2.51
The following nodes are configured with the common role "compute":
n[11-15]

Do the following to determine whether
or not you have to modify the default role assignments: See Appendix F for a description of the default role assignments
based on system size. Read about the special considerations
regarding the default role assignments to determine if the role assignments
are suitable for your environment. If you do not modify the role assignments,
the system will be configured with the default assignments. If you are configuring services for
improved availability, read the information in Table 1-2 if you need more information about role assignments. Ensure that the nodes you have associated into availability
sets are assigned with the appropriate roles so that service failover can
occur.
Use the Modify Nodes and Analyze options
on the cluster_config command-line menu to adjust the role
assignments and create an external Ethernet connection on any node, if required.
See Appendix G for information
about how to use the menu options. When you are satisfied with the
role assignments, enter the letter p to apply the configuration
to the system: [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 |
Do one of the following when this
prompt is displayed: [S]ervices Config, [P]roceed, [Q]uit: |
Enter the letter s to
perform customized services configuration. This option is intended for experienced
XC administrators who want to customize role services. Intervention like this
is typically not required for HP XC systems. HP recommends that you
enter p to continue with the system configuration process
and proceed to “Task 10: Respond to Configuration Questions”. Enter the letter p to
continue with the system configuration process. When
the system configuration process begins, the configuration and management
database is not consistent and complete again until after cluster_config processing
is complete. Therefore, do not press Ctrl+c during this time. Enter the letter q to
exit from the system configuration process. The following prompt is displayed
to give you the option to save your responses to the configuration and management
database: Do you want to apply your changes to the cluster configuration? [y/n] y |
Proceed to “Task 10: Respond to Configuration Questions” to respond to the remainder of the system configuration
questions. |
