Managing Serviceguard Sixteenth Edition, March 2009

— Both packages must be failover packages whose failover_policy is
configured_node.
— At least one of the packages must specify a priority (page 267).
For more information, see “About Package Dependencies” (page 166).
dependency_location
Specifies where the dependency_condition must be met.
• If dependency_condition is UP, legal values fordependency_location are same_node,
any_node, and different_node.
— same_node means that the package depended on must be running on the same
node.
— different_node means that the package depended on must be running on
a different node in this cluster.
— any_node means that the package depended on must be running on some
node in this cluster.
• If dependency_condition is DOWN, legal values fordependency_location are same_node
andall_nodes.
— same_node means that the package depended on must not be running on the
same node.
— all_nodes means that the package depended on must not be running on any
node in this cluster.
For more information, see “About Package Dependencies” (page 166).
weight_name, weight_value
These parameters specify a weight for a package; this weight is compared to a node's
available capacity (defined by the CAPACITY_NAME and CAPACITY_VALUE
parameters in the cluster configuration file) to determine whether the package can run
there.
Both parameters are optional, but if weight_value is specified, weight_name must also
be specified, and must come first. You can define up to four weights, corresponding
to four different capacities, per cluster. To specify more than one weight for this package,
repeat weight_name and weight_value.
NOTE: But if weight_name is package_limit, you can use only that one weight and
capacity throughout the cluster. package_limit is a reserved value, which, if used,
must be entered exactly in that form. It provides the simplest way of managing weights
and capacities; see “Simple Method” (page 175) for more information.
The rules for forming weight_name are the same as those for forming package_name
(page 262). weight_name must exactly match the corresponding CAPACITY_NAME.
