HP XC System Software Administration Guide Version 3.0
external_connection_desired Assigning 1 to this parameter indicates that an external
connection is beneficial, but not necessary.
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_desired, assign 0 to the
external_connection_required parameter.
exclusivity_desired Assign 1 to this parameter if the service would benefit enough
to justify having its own service node or nodes on a larger
system. If so, you must also specify the exclusivity_group
parameter.
Assign 0 if the service does not need the exclusive use of nodes.
exclusivity_group Provide a name for the nodes for the service. The name is an
alphanumeric identifier (underscore characters are permitted),
but it must begin with an alpha character.
Services specifying the same exclusivity group name are
assigned to the same node or nodes from the correspondingly
named group of exclusive nodes.
The analyze command of the cluster_config utility examines the parameters for each service.ini
file and generates a report like the following:
[L]ist Nodes, [M]odify Nodes, [A]nalyze, [H]elp, [P]roceed, [Q]uit: A
