NOTE: Any subnet that is configured in this
cluster configuration file as a SUBNET for IP
monitoring purposes, or as a monitored_subnet in
a package configuration file (or SUBNET in a
legacy package; see “Package Configuration
Planning ” (page 168)) must be specified in the
cluster configuration file via
NETWORK_INTERFACE and either
STATIONARY_IP or HEARTBEAT_IP. Similarly,
any subnet that is used by a package for
relocatable addresses should be configured into
the cluster via NETWORK_INTERFACE and
either STATIONARY_IP or HEARTBEAT_IP. For
more information about relocatable addresses,
see “Stationary and Relocatable IP Addresses ”
(page 90) and the descriptions of the package ip_
parameters (page 298).
IMPORTANT: See “Cross-Subnet
Configurations” (page 41) for important
information about requirements for such
configurations.
For information about changing the configuration
online, see “Changing the Cluster Networking
Configuration while the Cluster Is Running”
(page 367).
HEARTBEAT_IP IP notation indicating this node's connection to
a subnet that will carry the cluster heartbeat.
