Managing Serviceguard Eighteenth Edition, September 2010

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
(page 299), and “About Cross-Subnet Failover” (page 201).)
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 (page 289)), 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 (page 299) and “About Cross-Subnet Failover” (page 201).
New for modular packages. For legacy packages, see “Configuring Cross-Subnet
Failover” (page 383).
cluster_interconnect_subnet
Can be configured only for a multi-node package in a Serviceguard Extension for Real
Application Cluster (SGeRAC) installation.
NOTE: Serviceguard supports both IPv4 and IPv6 for an cluster_interconnect_subnet,
but before configuring an IPv6 subnet, make sure that your version of Oracle RAC also
supports IPv6 for this subnet.
See the latest version of Using Serviceguard Extension for RAC at
www.hp.com/go/hpux-serviceguard-docs for more information, including the
status of Oracle RAC support for an IPv6 cluster_interconnect_subnet.
New for A.11.18 (for both modular and legacy packages).
