IPv6 Network Support
Network Configuration Restrictions
Appendix H 529
• Quorum server, if used, has to be configured on an IPv4 network. It is
not IPv6-capable. A quorum server configured on an IPv4 network
can still be used by Serviceguard IPv6 clusters that have IPv6
networks as a part of their cluster configuration.
• Serviceguard supports IPv6 only on the Ethernet networks,
including 10BT, 100BT, and Gigabit Ethernet
NOTE Even though link-local IP addresses are not supported in the
Serviceguard cluster configuration, the primary link-local address on the
Serviceguard primary interface will be switched over the standby during
a local switch. This is because of two requirements: First, the dual stack
(IPv4/IPv6) kernel requires that the primary IP address associated with
an interface must always be a link-local address. Second, Serviceguard
requires that the site-local and global IPs be switched to the standby
network interface.
