•local_lan_failover_allowed. Use this parameter control whether a package fails or not when a primary LAN card fails on a cluster node and its IP addresses are transferred to a standby LAN card.

Legal values are yes and no. Default is yes.

See the parameter description (page 241) for more information.

•Use the monitored_subnet parameter to specify a subnet that is to be monitored for this package. If there are multiple subnets, repeat the parameter as many times as needed, on a new line each time.

In a cross-subnet configuration, configure the additional monitored_subnet_access parameter for each monitored_subnet as necessary; see “About Cross-Subnet Failover” (page 154) for more information.

•If this is a Serviceguard Extension for Oracle RAC (SGeRAC) installation, you can use the cluster_interconnect_subnet parameter (page 241).

•If your package will use relocatable IP addresses, enter the ip_subnet and ip_address addresses. See the parameter descriptions (page 242) for rules and restrictions.

In a cross-subnet configuration, configure the additional ip_subnet_node parameter for each ip_subnet as necessary; see “About Cross-Subnet Failover” (page 154) for more information.

•For each service the package will run, enter values for the following parameters (page 243):

◦service_name (for example, a daemon or long-running process)

◦service_cmd (for example, the command that starts the process)

◦service_fail_fast_enabled and service_halt_timeout if you need to change them from their defaults.

◦service_restart if you want the package to restart the service if it exits. (A value of unlimited can be useful if you want the service to execute in a loop, rather than exit and halt the package.)

•To monitor a crucial resource as part of a package using generic resources, enter values for the following parameters (page 244):

◦generic_resource_name to identify the generic resource in a package.

◦generic_resource_evaluation_type to define whether the status of the generic resource must be evaluated during or before the package is started.

◦generic_resource_up_criteria to determine the status of a generic resource based on the specified criterion.

See “Configuring a Generic Resource” (page 133) for more information.

•To configure the package to monitor a registered EMS resource, enter values for the following parameters (page 246):

◦resource_name

◦resource_polling_interval

◦resource_up_value

◦resource_start

See “Parameters for Configuring EMS Resources” (page 136) for more information and an example.

•If the package needs to mount LVM volumes to file systems, use the vg parameters (page 248) to specify the names of the volume groups to be activated, select the appropriate
