Managing HP Serviceguard for Linux, Tenth Edition, September 2012

Figure 12 After Package Switching
Failover Policy
The Package Manager selects a node for a failover package to run on based on the
priority list included in the package configuration file together with the
failover_policy parameter, also in the configuration file. The failover policy governs
how the package manager selects which node to run a package on when a specific
node has not been identified and the package needs to be started. This applies not only
to failovers but also to startup for the package, including the initial startup. The two
failover policies are configured_node (the default) and min_package_node. The
parameter is set in the package configuration file.
If you use configured_node as the value for the failover policy, the package will start
up on the highest priority node available in the node list. When a failover occurs, the
package will move to the next highest priority node in the list that is available.
