script_log_file
The script log file documents the package run and halt
activities. More details in Chapter 6, under
script_log_file (see page 285).
log_level Determines the amount of information printed to
stdout when the package is validated, and to the
script_log_file (see page 285) when the package is
started and halted. Valid values are 0 through 5; more
details in Chapter 6 under log_level (see page 285).
failover_policy
The policy used by the package manager to select the
node on which a failover package should be
automatically started.
Default is configured_node, which tells the package
manager to select the next available node in the list of
node names for the package. The order of preference is
the order of the node name entries in the package’s
configuration file.
The alternative policy is min_package_node, which
tells the package manager to select (from the list of
nodes that can run this package) the node that is
running the fewest packages.

failback_policy
The policy used to determine what action the package
manager should take if a failover package is not
running on its primary node (the first node on its
node_name list) and its primary node is capable of
running the package.
Default is manual, which means no attempt will be
made to move the package back to its primary node
when it is running on an alternate node. (This is the
same behavior as in previous versions of Serviceguard.)
The alternate policy is automatic, which means that
the package will be halted and restarted on its primary
node as soon as the primary node is capable of running
the package, and, if min_package_node has been
