Managing HP Serviceguard for Linux, Seventh Edition, July 2007

Cluster and Package Maintenance
Reviewing Cluster and Package Status
Chapter 7234
• Switching Enabled for a Node: For failover packages, enabled means
that the package can switch to the specified node. disabled means
that the package cannot 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 have halted or failed.
• Uninitialized. The service is included in the cluster configuration,
but it was not started with a run command in the master control
script.
• Unknown. Serviceguard cannot determine the status.
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 (see page 205), 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 (see page 202).
• min_package_node. The package fails over to the node in the cluster
with the fewest running packages on it.
