Managing Serviceguard Fifteenth Edition, reprinted May 2008

Configuring Packages and Their Services
Choosing Package Modules
Chapter 6 295
If you specify a subnet as a monitored_subnet the package will not run
on any node not reachable via that subnet. This normally means that if
the subnet is not up, the package will not run. (For cross-subnet
configurations, in which a subnet may be configured on some nodes and
not on others, see monitored_subnet_access below, ip_subnet_node
on page 296, and “About Cross-Subnet Failover” on page 191.)
Typically you would monitor the ip_subnet, specifying it here as well as
in the ip_subnet parameter (see below), but you may want to monitor
other subnets as well; you can monitor any subnet that is configured into
the cluster (via the STATIONARY_IP or HEARTBEAT_IP parameter in the
cluster configuration file).
If any monitored_subnet fails, Serviceguard will switch the package to
any other node specified by node_name which can communicate on the
monitored_subnets defined for this package. See the comments in the
configuration file for more information and examples.
monitored_subnet_access In cross-subnet configurations, specifies
whether each monitored_subnet is accessible on all nodes in the
package’s node list (see node_name on page 288), or only some. Valid
values are PARTIAL, meaning that at least one of the nodes has access to
the subnet, but not all; and FULL, meaning that all nodes have access to
the subnet. The default is FULL, and it is in effect if
monitored_subnet_access is not specified.
See also ip_subnet_node on page 296 and “About Cross-Subnet
Failover” on page 191.
New for modular packages. For legacy packages, see “Configuring
Cross-Subnet Failover” on page 390.
cluster_interconnect_subnet Specifies an IPv4 address. Can be
configured only for a multi-node package in a Serviceguard Extension for
Real Application Cluster (SGeRAC) installation.
(See the latest version of Using Serviceguard Extension for RAC at
http://www.docs.hp.com -> High Availability - > Serviceguard
Extension for Real Application Cluster (ServiceGuard OPS
Edition) for more information.)
New for A.11.18 (for both modular and legacy packages).
ip_subnet Specifies an IP subnet used by the package. Replaces
SUBNET, which is still supported in the package control script for legacy
packages.
