HP XC System Software Administration Guide Version 3.0

external_connection_desired = value
exclusivity_desired = value
These parameters are explained as follows:
service_recommended Assigning 1 to this parameter indicates that the service is part
of the default configuration. The cluster_config utility
recommends the assignment of nodes to this service.
Alternately, assigning 0 means that the cluster_config
utility does not interpret the service as part of the default
configuration.
optimal_scale_out Assign the scale-out value to this parameter. The scale-out value
is the number of nodes that this new service can service with
optimal performance. The cluster_config command divides
the total number of nodes in the HP XC system by this value to
obtain the number of server nodes for this service.
Assign 1000000 (one million) to this parameter if scaling is not
a factor.
head_node_required Assigning 1 to this parameter indicates that the service must
run on the head node.
Assigning 0 indicates that the service does not need to run on
the head node.
IMPORTANT
Do not assign 1 to both the head_node_required and
head_node_desired parameters. If you assign 1 to the
head_node_required, assign 0 to the
head_node_desired parameter.
head_node_desired Assigning 1 to this parameter indicates that running the service
on the head node is beneficial, but not necessary.
Assigning 0 indicates that the service does not benefit from
running on the head node.
IMPORTANT
Do not assign 1 to both the head_node_required and
head_node_desired parameters. If you assign 1 to the
head_node_desired, assign 0 to the
head_node_required parameter.
external_connection_required Assigning 1 to this parameter indicates that the service requires
an external connection.
Assigning 0 indicates the service does not require an external
connection.
IMPORTANT
Ensure that you do not assign 1 to both the
external_connection_required and
external_connection_desired parameters. If you assign
1 to the external_connection_required, assign 0 to the
external_connection_desired parameter.
