HP Fabric Clustering System HP-UX Administrator's Guide, March 2008

NOTE: Please refer to the Serviceguard Configuration Guide for complete details of the
supported SGeRAC configurations.
NOTE: Oracle RAC uses IPoIB for cache fusion traffic.
NOTE: IPV6 failover is not supported with ServiceGuard. IPoIB can run over IPV6, but the
InfiniBand switch does not support IPV6 address failover.
Using Serviceguard and IPoverIB
Serviceguard actively monitors IPoIB interfaces configured in the cluster and upon detecting
failure of the primary IPoIB interface(s), provides local IP address failover to any available
standby IPoIB interfaces.
Configuring IPoIB Interfaces for Serviceguard Clusters
Configuration of IPoIB interfaces in a Serviceguard cluster is not different from configuration of
any other LAN interfaces. The following diagrams show the supported configurations of IPoIB
as cluster heartbeat:
Supported Configuration #1: Single IB HCA, Single Serviceguard Heartbeat:
Supported Configuration #2: Multiple IB HCAs, Single Serviceguard Heartbeat:
Supported Configuration #3: Multiple IB HCAs, Multiple Serviceguard Heartbeats:
