cluster. HP recommends to upgrade all the cluster nodes to the new release level at the earliest.
Support for the Oracle Grid Infrastructure 11.2.0.2 HAIP with SGeRAC A.11.20
Starting with SGeRAC A.11.20, Oracle Grid Infrastructure 11.2.0.2 HAIP feature can be configured
and used in an SGeRAC cluster. All recommended network configuration of SGeRAC cluster are
not supported when using HAIP. For information about most recommended network configuration
of SGeRAC, see Using Serviceguard Extension for RAC manual (published on January 2012 or
later) at www.hp.com/go/hpux-serviceguard-docs —> HP Serviceguard Extension for RAC.
The following network configuration requirements must be met to use the Oracle Grid Infrastructure
11.2.0.2 HAIP feature in an SGeRAC cluster:
1. Any networks in the SGeRAC A.11.20 cluster configured for heartbeat must also be configured
as Oracle cluster interconnect network in the Oracle Grid Infrastructure 11.2.0.2. Similarly
any network configured for Oracle cluster interconnect must also be configured as SGeRAC
A.11.20 heartbeat network.
NOTE: Do not configure Serviceguard heartbeat and Oracle cluster interconnect in mutually
exclusive networks.
2. Serviceguard standby interfaces must not be configured for the networks used for Serviceguard
heartbeat and Oracle cluster interconnect.
