Managing Serviceguard Eighteenth Edition, September 2010

addresses themselves will be immediately configured into the cluster as stationary
IP addresses.
CAUTION: If you configure any address other than a stationary IP address on a
Serviceguard network interface, it could collide with a relocatable package IP
address assigned by Serviceguard. See “Stationary and Relocatable IP Addresses
” (page 90).
(Oracle VIPs are an exception to this rule; such configurations require the HP
add-on product Serviceguard Extension for Oracle RAC).
— Similarly, Serviceguard does not support using networking tools to move or
reconfigure any IP addresses configured into the cluster.
Doing so leads to unpredictable results because the Serviceguard view of the
configuration is different from the reality.
NOTE: If you will be using a cross-subnet configuration, see also the Restrictions
(page 42) that apply specifically to such configurations.
Redundant Ethernet Configuration
The use of redundant network components is shown in Figure 2-1, which is an Ethernet
configuration.
