Failover and Failback Policies
Packages can be configured with one of two values for the
FAILOVER_POLICY parameter:
• CONFIGURED_NODE. The package fails over to the next node in the
node list in the package configuration file.
• MIN_PACKAGE_NODE. The package fails over to the node in the cluster
with the fewest running packages on it.
Packages can also be configured with one of two values for the
FAILBACK_POLICY parameter:
• AUTOMATIC. With this setting, a package, following a failover, returns
to its primary node when the primary node becomes available again.
• MANUAL. With this setting, a package, following a failover, must be
moved back to its original node by a system administrator.
Failover and failback policies are displayed in the output of the cmviewcl
-v command.
