Managing HP Serviceguard for Linux, Tenth Edition, September 2012

switch to the specified node until the node is enabled to run the package via the
cmmodpkg command.
Every failover package is marked enabled or disabled for each node that is
either a primary or adoptive node for the package.
For multi-node packages, node switching disabled means the package cannot
start on that node.
Service Status
Services have only status, as follows:
• Up. The service is being monitored.
• Down. The service is not running. It may not have started, or have halted or failed.
• Unknown. Serviceguard cannot determine the status.
Generic Resource Status
Generic resources have only status, as follows:
• Up. The generic resource is up.
• Down. The generic resource is down.
• Unknown. Resource monitoring has not yet set the status of the resource.
Network Status
The network interfaces have only status, as follows:
• Up.
• Down.
• Unknown. Serviceguard cannot determine whether the interface is up or down.
Failover and Failback Policies
Failover packages can be configured with one of two values for the failover_policy
parameter (page 209), as displayed in the output of cmviewcl -v:
• configured_node. The package fails over to the next node in the node_name
list in the package configuration file (page 206).
• min_package_node. The package fails over to the node in the cluster with the
fewest running packages on it.
