HP Serviceguard manual Packagetype. Enter failover, multinode, or systemmultinode

NOTE: Optional parameters are commented out in the configuration file (with a # at the beginning of the line). In some cases these parameters have default values that will take effect unless you uncomment the parameter (remove the #) and enter a valid value different from the default. Read the surrounding comments in the file, and the explanations in this chapter, to make sure you understand the implications both of accepting and of changing a given default.

In all cases, be careful to uncomment each parameter you intend to use and assign it the value you want it to have.

•package_name. Enter a unique name for this package. Note that there are stricter formal requirements for the name as of A.11.18.

•package_type. Enter failover, multi_node, or system_multi_node.

(system_multi_node is reserved for special-purpose packages supplied by HP.) Note that there are restrictions if another package depends on this package; see “About Package Dependencies” (page 137).

See “Types of Package: Failover, Multi-Node, System Multi-Node” (page 228) for more information.

•node_name. Enter the name of each cluster node on which this package can run, with a separate entry on a separate line for each node.

•auto_run. For failover packages, enter yes to allow Serviceguard to start the package on the first available node specified by node_name, and to automatically restart it later if it fails. Enter no to keep Serviceguard from automatically starting the package.

•node_fail_fast_enabled. Enter yes to cause the node to be halted (system reset) if the package fails; otherwise enter no.

For system multi-node packages, you must enter yes.

•run_script_timeout and halt_script_timeout. Enter the number of seconds Serviceguard should wait for package startup and shutdown, respectively, to complete; or leave the default, no_timeout; see (page 236).

•successor_halt_timeout. Used if other packages depend on this package; see “About Package Dependencies” (page 137).

•script_log_file (page 237).

•log_level (page 237).

•failover_policy (page 237). Enter configured_node or min_package_node. (This parameter can be set for failover packages only.)

•failback_policy (page 238) Enter automatic or manual. (This parameter can be set for failover packages only.)

•If this package will depend on another package or packages, enter values for dependency_name, (page 238)dependency_condition, dependency_location, and optionally priority.

See “About Package Dependencies” (page 137) for more information.

NOTE: The package(s) this package depends on must already be part of the cluster configuration by the time you validate this package (via cmcheckconf(1m); see “Verifying and Applying the Package Configuration” (page 259)); otherwise validation will fail.

•To configure package weights, use the weight_name and weight_value parameters (page 240). See “About Package Weights” (page 144) for more information.
