Managing HP Serviceguard A.12.00.00 for Linux, June 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 (see “Package Configuration Planning” (page 103)) 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 60)
and the descriptions of the package ip_ parameters
(page 192).
For information about changing the configuration online,
see “Changing the Cluster Networking Configuration while
the Cluster Is Running” (page 241).
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 303). 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 241).
Heartbeat configuration requirements:
The cluster needs at least two network interfaces for the
heartbeat in all cases, using one of the following minimum
configurations:
