Managing HP Serviceguard A.11.20.20 for Linux, March 2014

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 104)) 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
and Monitored Subnets” (page 62) and the descriptions of
the package ip_ parameters (page 182).
For information about changing the configuration online,
see “Changing the Cluster Networking Configuration while
the Cluster Is Running” (page 230).
HEARTBEAT_IP IP notation indicating this node's connection to a subnet that
will carry the cluster heartbeat.

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 details of the IPv6 address format, see “IPv6
Address Types” (page 289). Heartbeat IP addresses on a
given subnet must all be of the same type: IPv4 or IPv6
site-local or IPv6 global.
For information about changing the configuration online,
see “Changing the Cluster Networking Configuration while
the Cluster Is Running” (page 230).
Heartbeat configuration requirements:
The cluster needs at least two network interfaces for the
heartbeat in all cases, using one of the following minimum
configurations:
