	(page 106).
	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 125)) 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 67) and the descriptions of the package ip_
	parameters (page 242).
	IMPORTANT: See “Cross-Subnet Configurations” (page 30)
	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 297).
HEARTBEAT_IP	IP notation indicating this node's connection to a subnet that
	will carry the cluster heartbeat.
	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 125)) 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 67) and the descriptions of the package ip_
	parameters (page 242).
	If HOSTNAME_ADDRESS_FAMILY is set to IPV4 or ANY, a
	heartbeat IP address can be either an IPv4 or an IPv6
	address, with the exceptions noted below. If
	HOSTNAME_ADDRESS_FAMILY is set to IPV6, all heartbeat
	IP addresses must be IPv6 addresses.
	For more information about the IPv6 address format, see
	“IPv6 Address Types” (page 378). Heartbeat IP addresses
	on a given subnet must all be of the same type: IPv4 or IPv6
	site-local or IPv6 global.
