IMPORTANT: For important information, see also “Cross-Subnet Configurations”
(page 32), the description of the HOSTNAME_ADDRESS_FAMILY, QS_HOST and
QS_ADDR parameters under Cluster Configuration Parameters (page 100), “Configuring
Name Resolution” (page 150), and the Release Notes for your version of Serviceguard
for Linux.
For special instructions that may apply to using IPv6 addresses to connect your version
of Serviceguard for Linux and the Quorum Server, see “Configuring Serviceguard to
Use the Quorum Server” in the latest version HP Serviceguard Quorum Server Version

Configuring IPv6 on Linux
Red Hat Enterprise Linux and SUSE Linux Enterprise Server already have the proper
IPv6 tools installed, including the /sbin/ip command. This section explains how to
configure IPv6 stationary IP addresses on these systems.
Enabling IPv6 on Red Hat Linux
Add the following lines to /etc/sysconfig/network:
NETWORKING_IPV6=yes # Enable global IPv6 initialization
IPV6FORWARDING=no # Disable global IPv6 forwarding
IPV6_AUTOCONF=no # Disable global IPv6 autoconfiguration
IPV6_AUTOTUNNEL=no # Disable automatic IPv6 tunneling
Adding persistent IPv6 Addresses on Red Hat Linux
This can be done by modifying the system configuration script, for example,
/etc/sysconfig/network-scripts/ifcfg-eth1:
DEVICE=eth1BOOTPROTO=static
BROADCAST=192.168.1.255
IPADDR=192.168.1.10
NETMASK=255.255.255.0
NETWORK=192.168.1.0
ONBOOT=yes
IPV6INIT=yes
IPV6ADDR=3ffe:ffff:0000:f101::10/64
IPV6ADDR_SECONDARIES=fec0:0:0:1::10/64
IPV6_MTU=1280
Configuring a Channel Bonding Interface with Persistent IPv6 Addresses on Red Hat
Linux
Configure the following parameters in
/etc/sysconfig/network-scripts/ifcfg-bond0:
DEVICE=bond0
IPADDR=12.12.12.12
